Unimec Screw Jack 6ol23

Ease of use and high reliability make UNIMEC trapezoidal screw jacks suitable for a wide variety of uses. They can be employed to lift, pull, move, or align any kind of loads, with a perfect synchronism which can hardly be obtained with other handling methods. UNIMEC trapezoidal screw jacks are absolutely irreversible, that is, they can their applied loads without needing any brakes or other locking systems. The screw jacks can be employed singularly or in groups properly connected with shafts, ts, and/or bevel gearboxes. They can be driven by different motors: electrical, with either alternating or direct current, as well as hydraulic or pneumatic motors. Also they can be driven manually or with any other type of transmission. In addition to the models shown on the following pages, UNIMEC can produce custom designed screw jacks to meet all the requirements. UNIMEC trapezoidal screw jacks are designed and manufactured using innovative technology so to supply a product which identifies itself with the state of the art in the transmission devices.

trapezoidal screw jacks The highest quality and a 28 years long experience are able to meet the most demanding and sophisticated requirements. The outer surfaces are completely machine finished and the parts are assembled with special care, in order to allow the application of s, flanges, pins, or any other components a project may require.The application of double guides throughout the product line provides a very good running efficiency even under the most strenuous operating conditions. Special sealing systems enable the inner gears to operate in a bath of lubricant, which guarantees them a long lasting life.

Models TP model: threaded spindle with axial translation. The input rotation of the worm screw is transformed in the axial translation of the threaded spindle by means of the worm wheel. The load is applied on the threaded spindle which must have a rotational constraint.

Tr a p e z o i d a l s c r e w j a c k s TPR model: with rotational threaded spindle and external nut (lead nut). The input rotation of the worm screw causes the rotation of the threaded spindle which is attached to the worm wheel. The load is applied to an external nut (lead nut) which must have a rotational constraint.

End fittings To meet the widest possible range of needs, various types of end fittings are available, which can be custom made upon request.

Casings Casings are made of various materials depending on the size of screw jacks. For screw jacks of the 183 series, casings are made of cast aluminium AlSi12 (according to the UNI EN 1706:1999 requirements), for the series between the sizes 204 and 9010, casings are made of grey cast iron EN-GJL-250 (according to the UNI EN 1561:1998 requirements); and for the extra heavy series, from size 10012, the casing is made of electro-welded carbon steel S235J0 (according to the UNI EN 10025-2:2005 requirements).

Worm screws For the entire screw jacks line, worm screws are made of a special steel 16NiCr4 (according to the UNI EN 10084:2000).They undergo thermal treatments like case-hardening and carburizing before being thoroughly ground both on the threads and on the tangs.

Worm wheel and nut The worm wheels and nuts (lead nuts) are made of a special high-resistance aluminium bronze CuAI10Fe2-C (according to the UNI EN 1982:2000 requirements). The trapezoidal geometry of the threading meets the requirements of the ISO 2901:1993 norm. The worm wheels toothing profile has been designed especially for our screw jacks and can easily a heavy-duty use.

Threaded spindles The threaded spindles are mainly manufactured by rolling carbon steel C 45 grounded bars (according to the UNI EN 10083-2:1998 requirements). Said process, which is temperature controlled, allows to include in our standard production 6 meter long bars. The trapezoidal geometry of the threading meets the requirements of the ISO 2901:1993 norm. Threaded spindles made of stainless steel AISI 316 or other materials can be manufactured upon request for length up to 12 meters.

Protections Protections can also be applied in order to prevent dust and foreign matters from coming into with the coupling and causing damages to the threaded spindle and its nut. For TP models, a steel rigid tube can be provided on the back side, while the front side can be protected by polyester and PVC elastic bellows. In TPR models only elastic protections can be applied.

Bearings and market materials Top-quality bearings and market materials are used for the whole line.

GLOSSARY

LOAD ANALYSIS AND COMPOSITION Choosing the right screw jack, and hence also its proper functioning, mostly depends on the identification of the real load acting on the screw jack. Loads can be divided in two main groups: static loads and dynamic loads; these groups are further made-up of: traction loads, compression loads, lateral loads, radial loads, eccentric loads, loads from shocks, loads from vibrations. STATIC LOADS A static load is the force that will be applied to the screw jack transmission devices while they are not in motion. DYNAMIC LOADS A dynamic load is the force that will be applied to the screw jack transmission devices while they are in motion. TRACTION LOADS A traction load is the force applied to the threaded spindle axis with an opposite direction to the casing.

COMPRESSION LOADS A compression load is a force applied to the threaded spindle axis with the same direction as the casing.

LATERAL LOADS A lateral load is a force applied perpendicular to the threaded spindle axis.

ECCENTRIC LOADS An eccentric load is a force whose centre of application does not belong to the threaded spindle axis, even having the same direction.

28

LOADS FROM SHOCKS A load from shocks is a load where the impulse forces generated by an impact are not quantifiable. LOADS FROM VIBRATIONS A load from vibrations is applied when a shock load increases the impulse frequency. Depending on the type of load some solution must be applied during the design phase: STATIC TRACTION LOAD The maximum applicable load for all models and sizes is shown in the specification tables. Shocks and/or lateral loads limit its applications. DYNAMIC TRACTION LOAD The maximum dynamic traction load which can be applied to a screw jack does not only depend on its size: it could be limited by the ambient temperature, service factors and possible lateral loads and/or shocks. It is thus necessary to check all those parameters. STATIC COMPRESSION LOAD The maximum load which can be applied is determined by the length of the threaded spindle as well as by the constraints it undergoes.The limit applicable load can be obtained on the basis of the Euler diagrams. Its application could be limited by possible shocks and/or lateral loads. DYNAMIC COMPRESSION LOAD The maximum compression load which can be applied is determined by many factors: the length of the threaded spindle, the ambient temperature, service factors and possible lateral loads and/or shocks. In addition to all the verifications already foreseen in the case of a traction load, further verifications are necessary relative to the Euler diagrams. STATIC LATERAL LOAD This kind of load induces a lateral shifting of the threaded spindle causing a damaging bending which limits the ability of the screw jack. Suitable graphs show the maximum lateral load values according to the length and size of the threaded spindle. For any further and more detailed verifications our technical office is at your disposal. DYNAMIC LATERAL LOAD A lateral load in dynamic applications is not allowed. In case of essential use of screw jacks with lateral load is for machine requirements, it will be necessary to our technical office. ECCENTRIC STATIC LOAD An eccentric load in static applications induces the same problems as the lateral loads. For this reason the above considerations are also applicable to this kind of load. DYNAMIC ECCENTRIC LOAD In case of handling an eccentric load, in order to avoid problems due to lateral load, it is necessary to create a suitably guided and sized mechanical structure, in order to absorb all the lateral components of the load. The guide must be realized very carefully: too narrow backlashes could cause seizure and stick-slips, while too rough backlashes would make useless the construction of the guide itself.

DYNAMIC LOAD FROM VIBRATIONS OR SHOCKS A dynamic load from vibrations or from shock can be damaging for the screw jack: stick-slip phenomena and consequent local overloads can enormously increase the wear conditions. It is necessary to minimize the shocks entity and the vibrations width

29

loads

STATIC LOAD FROM VIBRATIONS OR SHOCKS A load from vibrations or from shock, if not very heavy, could be the only reasons for the reversibility of the transmission moved by the screw jack. In that case it is advisable to our technical office in order to the screw jack applicability.

BACKLASH Backlash on the worm screw The worm screw – worm wheel coupling has a small degree backlash. Due to the reduction ratio and the transformation from the rotation movement to the translation movement, this backlash becomes an error of less than 0,05 mm in the linear positioning of the threaded spindle.

Lateral backlash in TP models The thread spindle and worm wheel coupling presents a natural and necessary lateral backlash indicated by A in the drawing below.The use of a double serial guide allows to minimize the entity of said backlashes, while keeping the spindle and nut axes aligned. The angular backlash on the coupling is translated on the spindle end fitting into a linear measure whose value depends on the size of the screw jack and grows according to the length of the spindle itself. Traction loads tend to reduce this backlash, while compression loads induce the opposite effect.

Lateral backlash in TPR models In TPR models the spindle and the worm wheel are locked by means of a double pins. UNIMEC carries out this operation by means of a suitable machine which keeps the axes of the two components coincident during the two drillings and the consequent pins insertions. Hence, the threaded spindle rotates minimizing the oscillations due to concentricity errors. For a proper operation it is necessary for the to provide solutions able to keep the spindle and the lead nut aligned.The guides can be external or directly implicate the structure of the lead nut, as can be seen in the following drawings. Drawing A: the lead nut is connected to the load by means of particular screws which allow it to fit into the threaded spindle position. The guides must be realized externally. Drawing B: The lead nut, which has been properly milled, is connected to the load by means of brackets which ensure anti-rotation. The brackets must be realized externally. Drawing C:The lead nut, which has been properly milled, is connected to the load by means of brackets which ensure anti-rotation. The upper additional ring acts as a guide. Drawing D: The double ring guarantees a higher reliability with respect to the C system.

Axial backlash In B the axial backlash between the threaded spindle and its nut (either a worm wheel or a lead nut) is caused by the natural and necessary tolerance characterizing this kind of couplings. For construction purposes it is only important in the case where the load changes its direction of application. For applications where there can be reciprocating traction and compression loads, and therefore a need to compensate the axial backlash, it is possible to apply a backlash reduction system. The axial backlash reduction must not be forced in any case, in order to avoid that the screw and the nut get blocked.

HANDLINGS Manual operation All screw jacks in the series can be manually operated. The following table expresses in [daN] the maximum load that can be handled according to the reduction ratio of screw jacks, considering the application of a force of 5 daN on a handwheel having a radius of 250 mm. Obviously, greater loads can be manually handled by applying further reductions to the screw jack or by increasing the radius of the handwheel.

Motorized operation Motors can be used for all jacks in the series. As a standard production, for the IEC unified motors, it is possible to connect them directly to screw jacks having a size between 204 and 8010. Special flanges can be made for hydraulic, pneumatic, brushless motors, as well as for direct current motors, permanent magnet motors, stepper motors and other special motors. In the case where it is not possible to motorize a screw jack directly, a connection by means of a bell house and a t can be foreseen. In special cases it is also possible to motorize size 183 and the s over 8010.The power tables determine, in case of unit service factors and for every single screw jack, the moving power and the input torque according to the size, the ratio, the dynamic load and the linear speed.

Rotation directions The rotation directions and the respective linear movements are showed in the drawings below. In standard conditions UNIMEC supplies screw jacks equipped with right handed worm screw, to which the movements illustrated in drawings 1 and 2 correspond. Upon request it is possible to have a left-handed worm screw, which the movements illustrated in drawings 3 and 4 correspond to. The combinations between threaded spindles and left-handed or right-handed worm screw, lead to the four combinations listed in the table below. We remind, that UNIMEC’s standard production does not include motorized left-handed worm screw.

Emergency operation In case of black-out, in order to be able to operate the single screw jacks or the complete structures by means of a crank, a free end on the screw jack worm screw or on the transmission is to be foreseen. In case of selfbraking motors or worm screw motor reducers, the brake must firstly be released and then it is necessary to disassemble those components from the transmission as the reducer could also be irreversible. It is advisable to equip the emergency operation mechanism with a safety device to cut the electric circuit.

Lubricating the threaded spindle is an important and determining factor in the proper functioning of the screw jack. It must be carried out at regular intervals that can assure a constant coat of clean lubricant between the parts. Insufficient lubrication, the use of an oil without extreme pressure additives or an improper lubrication can lead to abnormal overheating and consequent wear phenomena, which naturally reduce the operating life of the screw jacks. In case the screw jacks are not visible or the threaded spindles are covered by protections, it is necessary to periodically the lubrication conditions. For heavier duties than those showed in the relative tables it is recommended to our Technical office.

32

Semi-automatic lubrication Many different systems of automatic lubrication are feasible, only the most common ones are listed as follows: 1 - For vertically mounted TP model screw jacks, it is possible to provide an oil bath rigid protection (with recirculation option) or, in case of high performances, a single chamber operation.This kind of lubrication will be described in details on page 68-69. 2 - Application of a additional ring on the cover in order to create a lubricant recovery tank. 3 - Use of a lubricant drop-applicator to be applied to a hole made in the cover for TP models, and in the lead nut for TPR models.

Centralized lubrication

lubrication

Many automatic lubrication systems with a central pump and various distribution points are also possible. The amount of lubricant required depends on the duty and work environment. A centralized dosing system does not exclude a periodic check of the lubrication conditions in the threaded spindle.

INSTALLATION AND MAINTENANCE Installation The screw jack must be installed in a manner that does not create lateral loads on the threaded spindle. Great care must be taken to ensure that the threaded spindle is orthogonal to the mounting plane, and that the load and threaded spindle are on the same axis. Employing multiple screw jacks to handle the same load (see the mounting schemes section on pages 90-91) requires further verifications: it is critical that the load points, (the end fittings for TP models and the lead nuts for TPR models), are perfectly aligned in order that the load can be uniformly distributed; otherwise the misaligned screw jacks would act as brake or counter-load. Whenever several jacks have to be connected by means of transmission shafts, it is recommended that they be perfectly aligned in order to avoid overloading of the worm screws. It is advisable to use ts capable of absorbing alignment errors but having, at the same time, a rigid torsion necessary to keep the synchronization of the transmission. The assembly or disassembly of the ts or pulleys of worm screw must be carried out by means of tie rods or extractors, using, if necessary, the threaded hole on top of the worm screw; striking or hammering could damage the inner bearings. For heat-shrinking ts or pulleys, we recommend a temperature between 80-100 °C. Installations environments with dust, water, vapors, etc. require precautions to protect the threaded spindle.This can be done by using elastic or rigid protections. The above protections are also used in order to avoid any accidental human with the moving devices. For civil applications it is always advisable to use the safety components.

Preparing for service All UNIMEC’s screw jacks are supplied filled with long lasting lubricant which ensures a perfect lubrication of the worm gear/worm wheel group and all the inner parts. All screw jacks (except for the size 183) are equipped with a lubricant plug for filling-up the lubricant as necessary. As clearly explained on relative paragraph, lubrication of the threaded spindle is a ’s responsibility and must be carried out periodically depending on the duty conditions and the operating environment. Special systems are available for holding the screw jacks in any position without creating leakage problems. The application of some accessories can limit these assembly possibilities: the various solutions to be adopted will be explained in the relevant paragraphs.

Start-up All screw jacks undergo a careful quality examination before being delivered to the client, and are dynamically tested load-free. When starting-up a machine where screw jacks are installed, it is critical to check for the lubrication of the threaded spindles and for the absence of foreign material. During the calibration phase of the electrical end-of-stroke systems, the inertia of the moving masses should be taken into , which for vertical loads will be lower in ascent and greater in descent. It is advisable to startup the machine with the minimum possible load and to make sure all components are working properly, before assuming regular operation. Especially at start-up, it is critical to follow the instructions given in the manual: continuous or hazardous testing maneuvers could lead to an abnormal overheating of the screw jacks and cause irreparable damages. One single temperature peak is enough to cause premature wear or breakdown of the screw jack.

34

Routine maintenance Screw jacks must be periodically inspected, depending on the level of use and working environment. It is advisable to check for lubricant leakages from the casing, and, if this occurs, it is necessary to find and eliminate the cause and fill the lubricant up the correct level. The lubrication conditions of the threaded spindle must be periodically inspected (and restored if necessary) as well as the presence of any foreign material. The safety components must be inspected according to the applicable norms.

Storage Screw jacks must be protected from deposits of dust and foreign matter during storage. Particular attention must be paid to saline or corrosive atmospheres. We also recommend to: 1 - Periodically rotate the input shaft to ensure proper lubrication of the inner parts and avoid that the seals dry up, therefore causing lubricant leakages. 2 - Lubricate and protect the threaded spindle, the worm screw and the non varnished components. 3 - the threaded spindle in case of horizontal storage.

A - THE APPLICATION DATA For a right dimensioning of the screw jacks it is necessary to identify the application data: LOAD [daN] = the load is identified with the force applied to the translating device of a screw jack. Normally the dimensioning is calculated considering the maximum applicable load (worst case). It is important to consider the load as a vector, which is defined by a modulus, a direction and a sense: the modulus quantifies the force, the direction orients spatially and gives indications on the eccentricity or on possible lateral loads, the sense identifies the traction or compression load. TRANSLATION SPEED [mm/min] = the translation speed is the load handling speed. From this speed it is possible to calculate the rotation speed of the rotating devices and the necessary power for the movement. Wear phenomena and the life of the screw jack proportionally depend on the value of the translation speed. Therefore, it is advisable to limit the translation speed in a way not to exceed the input speed of 1500 rpm on the worm screw. Input speeds up to 3000 rpm are possible but in such case we suggest ing our technical office. STROKE [mm] = it is the linear measure used to handle a load. It does not always coincide with the total length of the threaded spindle. AMBIENT VARIABLES = these values identify the environment and the operating conditions of the screw jack. Among them: temperature, oxidizing and corrosive factors, working and non-working periods, vibrations, maintenance and cleaning, lubrication quality and quantity etc. MOUNTING SCHEMES = There are several ways of handling a load by means of screw jacks. The schemes on pages 90-91 will show you some examples. Choosing a mounting scheme will condition the choice for the size and the power which is necessary for the application.

B - THE UNIT LOAD AND THE DESCRIPTIVE TABLES According to the n number of screw jacks contained in the mounting scheme it is possible to calculate each screw jack’s load by dividing the total load by n. In case the load is not fairly distributed in all screw jacks, it is recommended to consider the transmission having the heaviest load, by virtue of a dimensioning based on the worst case.

C – THE EQUIVALENT LOAD All the values listed in the catalogue refer to standard use conditions, i.e. under a temperature of 20 °C and working percentage of 10%. For different operation conditions the equivalent load should be calculated: it refers to the load which would be applied in standard conditions in order to have the same thermal exchange and wear effects, which the real load achieves in the real conditions of use. It is therefore advisable to calculate the equivalent load according to the following formula: Ce = C•ft•fa•fs

The temperature factor ft

By means of the following diagram an ft factor can be calculated according to the ambient temperature. In case of temperatures higher than 80 °C we suggest ing our technical office.

The service factor fs The service factor fs is obtained by evaluating the working cycle and calculating the operation percentage on that interval. For example a working time of 10 minutes and non working time of 10 minutes correspond to 50%; similarly a working time of 5 minutes and a non working time of 20 minutes correspond to 20%. Based on the working data, choosing the cycle time and the operation percentage it is possible to read the fs value on the ordinate axis.

With the aid of the descriptive tables it is possible to check whether the previously chosen size is able to an issible dynamic load equal to the equivalent load. If not, it is necessary to effect a second choice.

D – THE POWER TABLES AND THE EQUIVALENT POWER The power tables are listed from page 46 to page 59. Choosing the tables referring to the size selected in paragraph C and putting the equivalent load values as well as the translation speed values in the table, it is possible to obtain the equivalent power Pe value. If the crossing values fall into the coloured area, this means that the application conditions could cause negative phenomena such as overheating and strong wear. It is therefore necessary to reduce the translation speed or to increase the size.

41

dimensioning

The equivalent power is not the power requested by the single screw jack, unless the three correction factors ft, fa and fs have a unit value.

E – BUCKLING In case of compression load, even occasional, it is necessary to check the buckling structure. Firstly the two constraints which the screw jack have to be determined: the first one is on the end fitting for TP models and on the lead nut for TPR models, while the second one is the way the casing is grounded. Most part of the real cases can be schematized according to three models, as listed below: End fitting – lead nut

Screw jack

Free Hinge Sleeve

Euler I Euler II Euler III

Once the Euler case has been determined which most fits to the current application, it is necessary to find in the corresponding diagram the point corresponding to the coordinates (length; load). The sizes suited to the application are those whose curves subtend the above point. In case the size chosen at paragraph D does not meet such requisites it is necessary to choose a higher size. The Euler-Gordon-Rankine curves have been calculated with a factor of safety equal to 4. For applications which can factors of safety lower than 4 we suggest ing our technical office. EULER 1

F – THE LATERAL LOAD As stated in the previous paragraphs lateral loads are the main cause of failures. In addition to the misalignment of the threaded spindle and the load, they can be caused by inaccurate mountings which force the threaded spindle in an anomalous position. As a consequence the coupling between lead nut and threaded spindle for TPR model and between the threaded spindle and the worm wheel for the TP model will be wrong.The application of double serial guides allows, for TP models, a partial correction of the anomalous position of the threaded spindle before ing the worm wheel. The problem is transformed into a sliding of the threaded spindle on the guides themselves. In TPR model, it is the outer nut which s the threaded spindle and it is therefore not possible to apply any corrections, unless particular mountings are applied as illustrated in the paragraph “lateral backlash in TPR models”. Lateral loads can even derive from an horizontal mounting: the threaded spindle own weight causes a bending of the same, becoming in this way a lateral load. The border value for the bending and the consequent lateral load depends on the screw jack size and on the threaded spindle length. It is advisable to our technical office in order to foresee the suitable s. The following diagrams, which are valid for static loads, show the issible lateral load value, according to the size and the length of the threaded spindle. For dynamic applications it is necessary to ask to the technical office.

In case the size chosen in the previous paragraphs is not enough to a particular lateral load, a suitable size should be chosen.

G – THE TORQUE At this stage it is possible to calculate the power requested by the mounting. The following formula will be used to calculate this value: P=

1 n•C•v • 1000 6000•ηm•ηc•ηs

where: P = n = C = v = ηm = ηc = η 44 s =

requested power [kW] number of screw jacks unit load [daN] translation speed [mm/min] screw jack running efficiency (see descriptive tables) configuration running efficiency = 1 - [(N-1) • 0,05], where N is the total number of screw jacks and gear boxes structure running efficiency (guides, belts, pulleys, shafts, ts, reducers)

In order to complete the calculation of the requested power it is necessary to calculate the torque which should be transmitted by the drive shaft: Mtm =

955•P ωm

where: Mtm = is the torque on the drive shaft [daNm] P = is the motor power [kW] ωm = is the angular speed of the motor [rpm]

According to the applied mounting scheme it is necessary to check that the worm screw will be able to hold out under a possible combined torque. In the following table the issible torque values are listed for the worm screws according to their size and expressed as [daNm].

PRO oil bath rigid protection

S3

S3

+ stroke

+ stroke

The application of an oil bath rigid protection, apart from representing a rigid protection, also allows to have the advantages of a semi-automatic lubrication. The lubricant must be added when mounting, with the jack completely closed, using the oil fill plug. Upon maneuvering the threaded spindle will be soaked with lubricant. In case the threaded spindle is left out of the protection for a long period, it could dry up so to make the PRO protection useless. For long strokes, in order to compensate the pump effect, it is necessary to mount an oil recirculation pipe (TRO) allowing lubricant to flow back inside the protection from the casing. It’s suggested the use of extremely high viscosity oils [2200 mm2/s] or high viscosity oils [220 mm2/s] with EP addictives in percentage of 15 – 20 %. Both solutions must present EP addictives for extreme pressures.We remind that the area indicated in the drawing could present lubricant drops: a vertical mounting will therefore avoid any leakage problems.The PRO protection can only be applied to TP models.The overall dimensions are shown in the following table.

In some applications the service factor can be so high requesting a continuously spindle lubrication. In these cases, if the screw jack is mounted such a way not to allow oil losses from the indicated areas, it’s possible a special oil proof assembling, where internal gears are lubricated in an oil bath. It’s imperative that the oil fulfilling will be done with spindle in all-closed position. In case the threaded spindle is left out of the oil proof chamber for a long period, it could dry up, so make the CU assembling useless. In order to guarantee the right adhesion, it’s suggested the use of extremely high viscosity oils [2200 mm2/s] or high viscosity oils [220 mm2/s] with EP addictives in percentage of 15 – 20%. Both solutions must present EP addictives for extreme pressures. CU is suitable only for TP models. The overall dimensions are shown in the table below.

If there’s the necessity the spindle, in case of extra-stroke, not to withdraw from the jack body, it’s possible assembling a steel withdrawing bush. The BU has a trapezoidal thread, able to sustain the load in extra-stroke case.The BU can apply only in TP models. In case of PRF stroke control, the Bu has the function of end-of-stroke too. It’s important underline that one only extra-stroke attempt (and the consequent impact between BU and the carter) can hopeless damage the transmission.

PRF stroke control

stroke

In order to meet the requirement of an electric stroke control it is possible to apply to a rigid protection suitable s for end-of-stroke. In the standard version these s are of two types and they are placed at the ends of the stroke in one of the four positions shown below. They are carried out in such a way as to allow a small adjustment. In case more than one end-of-stroke are needed, it is possible to provide intermediate s or a continuous for the requested length. In order to enable the end-of-stroke to operate, a steel bushing is mounted on the threaded spindle. More bushings can be mounted upon request. The PRF can only be applied to TP models and in case of missing specifications it will be supplied with the s mounted according to position 1. Sensor are supplied only on demand. The overall dimensions are shown in the table below. Moreover it’s possible assembling magnetic sensors on the protection, avoiding to mill it. The end-of-stroke signal is given by a magnet attached on the bottom of the spindle. Incompatibility: TPR – PRO models - CU

PE elastic protection The purpose of the elastic protections is to protect the threaded spindle by following its own movement during stroke. Standard type protections are elastic bellows, made of polyester covered nylon and can have, as serial, collars or flanges at their ends whose dimensions are shown in the table 1 below. Special implementations are available upon request, as well as a fixing by means of iron. Fixing flanges can be in plastic or metal. Special materials for the bellows are also available: Neoprene® and Hypalon® (water sea environment), Kevlar® (resistant to cuts and abrasion), glass fiber (for extreme temperatures, from -50 to 250°C) e aluminized carbon (it’s an auto-extinguish material for limit applications with molten metal spits). The PE standard material is guarantee for ambient temperature between -30 and 70°C. If it’s needed a waterproof elastic bellow, it’s possible to realize protections whose bellows are not sewed but heatsealed. This kind of protection is not able to solve condensate problem. Moreover, it’s possible to have metal protections on demand; such requests are be submitted to the Technical Office. Besides further implementations made of special materials fire-resistant and cold-resistant materials as well as of materials suited for aggressive oxidizing environments can be supplied. In case of long strokes internal anti-stretching rings are previewed in order to guarantee an uniform bellows opening.

The application of elastic protections on the screw jacks may implicate some dimensioning amendments due to the PE own sizes, as shown in table n.2. Further, in completely close conditions, the PE has an overall dimension equal to 1/8 of the stroke value. In case said value exceeds the C1 quote (which can be taken from the dimension tables on pages 60-63), the total length of the threaded spindle should be fitted to said dimensions. In case of horizontal mounting (of which previous notice should be given) it is necessary to the protection weight itself in order to avoid that it leans on the threaded spindle; for this purpose special rings are foreseen. The PE can be applied to TP and TPR models and in case of missing specifications they can be supplied with fabric collars and the dimensions shown in table 1, supposing that a vertical mounting is carried out.

PRA double guide anti-rotation

A + stroke

A + stroke

As all screw jacks must have an anti-rotation, in case such constraint cannot be realized externally, it is possible, for TP models, to have an inner anti-rotation system inside the screw jack. Two guides are mounted on the rigid protection where a bronze bushing, which is attached to the threaded spindle, can slide. In case of very long strokes it should be checked that the torsional sliding is not such as to force the fixing screws in the guides. As the inner anti-rotation constraints the threaded spindle and its end fitting, in case of presence of holes, like in TF and TOR end fittings, their position should be indicated, as shown in the drawings below. Unless otherwise stated all screw jacks will be delivered in position 1 or 3. The overall dimensions are shown in the table below. Incompatibility: TPR models – ALEPH series – AR

AR grooved spindle anti-rotation Another inner anti-rotation system which is only available for TP models is the grooved spindle. It provides a continuous milling along the threaded spindle length where an hardened key, having seat in the cover of the screw jack, can slide; it ensures an anti-rotation. As this accessory foresees a cut interrupting the threads continuity, the spindle mechanical strength itself is reduced: a reduction of the load capacity has to be taken into s reported in the table below. In addition, also due to said grooving on the threaded spindle, in order to limit wear phenomena, the AR should be used when the fa factor is lower than or equal to 1. As the inner anti-rotation constraints the threaded spindle and its end fitting, in case of presence of holes, like in the TF and TOR end fittings their position should be indicated, as shown in the drawings below.

CS Safety lead nut for monitored wear control In many applications it is necessary to ensure that the screw jack can safely the load even under wear conditions of the main nut, be it the worm wheel or the lead nut. The safety lead nut has been designed for that purpose: it couples to the nut through an insert and follows its movement. When the main nut starts wearing out, the axial backlash in the threaded spindle coupling is increased, and, under a load, the safety lead nut gets closer to the nut, starting to part of the force acting on it. This phenomenon means a reduction of the L or L1 quote (according to the model). When this reduction reaches the X value indicated in the table below, the nut and the safety lead nut must be replaced, otherwise the wear phenomena could cause a collapse of the load. Just after mounting, it is therefore necessary to periodically measure the L or L1 quote, in order to check the wear conditions of the components. A safety lead nut only works in one way: either it ensures the traction load or the compression load . Unless otherwise stated, all screw jacks will be delivered in the drawing configurations 1 and 3 and for a compression load. We remind that the area indicated in the drawing could present lubricant drops: a vertical mounting will therefore avoid any leakage problems. The overall dimensions are shown in the following table.

SUA lead nut for automatic wear control for TPR models

RG Anti axial backlash lead nut As already explained in the previous paragraphs, the coupling between the threaded spindle and its nut, be it the worm wheel or the lead nut, represents a natural axial backlash. If, for mounting requirements and under a load which changes its direction, from traction to compression and vice versa, it is necessary to reduce the axial backlash, an anti axial backlash lead nut can be applied. The RG lead nut is linked to the nut through an insert and it is attached to it by means of dowels in TPR model, and by means of the contrast cover in the TP models. Closing the dowels or rotating the cover are the actions requested to reduce the axial backlash. Be careful with an excessive backlash reduction: you could assist to huge wear phenomena and the nut could grip on the spindle due to the difference in the two pitch errors. The application of the anti axial backlash system reduces the screw jack running efficiency by 40%. We remind that the area indicated in the drawing could present lubricant drops: a vertical mounting will therefore avoid any leakage problems. The overall dimensions are shown in the following table.

CR worm wheel rotation control In some cases it can be necessary to check the operation conditions of the screw jack monitoring the worm wheel rotation, both in TP models and in TPR models. A milling is carried out on the worm wheel and a suitable proximity switch supplies an electric impulse for each turn. No impulse means that the transmission is stopped. Special executions with more impulses per round are always possible. Incompatibility: ALEPH series – size 183

CT- CTC Temperature control


81

accessories

Due to the fact that they are irreversible transmissions, a big amount of input power is lost by mechanical screw jacks and it is therefore transformed into heat. It is possible to control temperature both on the casing (CT) and on the lead nut (CTC) by means of a thermal probe emitting an electric impulse when the preset temperature of 80 °C is reached. Moreover it’s possible to apply a sensor able to catch the temperature exact value and to send to a plc an electric signal proportional to the above mentioned value. Incompatibility: ALEPH series

SP Additional mounting plates If for mounting requirements it is necessary to fix the screw jacks on holes which do not coincide with the casing holes, steel mounting plates can be supplied.

PO Rigid rocking protection

L + stroke

When it is necessary to apply a rocking mounting, UNIMEC is able to offer, for TP models, a special rigid reinforced protection which has an eyelet at its end. This protection very often s the load, and it is therefore advisable that this protection be not too long in order to avoid an anomalous bending of the PO. Further, it should be reminded that mounting a PO in combination with an end fitting having an eyelet does not automatically give to the screw jack the status of a connecting rod (absence of lateral loads). In case of compressive loads, the buckling verification must be calculated on a length equal to the hinges distance. Motors can directly be assembled to the screw jack. The overall dimensions are shown in the following table. Incompatibility: TPR models - ALEPH series sizes 183, 10012, 12014, 14014, 16016, 20018, 25022 - P - PR - PRO - SP - PRA

P Lateral pins The purpose of this solution is very similar to the PO one: two lateral pins are fixed on the screw jack body in order to allow a rocking mounting. For some aspects this solution can be preferred as to the rocking protection because, in the slender rod scheme, the distance between the two hinges is exactly half. Further we remind that mounting lateral pins combined with an end fitting having an eyelet does not automatically give to the screw jack the status of a connecting rod (absence of lateral loads). In case of compressive loads, the buckling verification must be calculated on a length equal to the hinges distance. Motors can directly be assembled to the screw jack.

DA double action model The double action model satisfies the need to move two nuts with a unique kinematic. The spindle protrudes from both screw jack faces and may have two configurations: DXSX: the spindle is right threaded by one face and left threaded by the other one. The kinematic presents opposite shifts, as shown in fig. 1. DXDX: the spindle is completely right threaded. The kinematic presents the same shift direction, as shown in fig. 2. Like kinematics, also loads can have the same or the opposite directions. This is the origin of the problems shown below. Moreover it’s important that the verification at the equivalent power must be always done considering both loads.

a)

b)

c) The verification at buckling must be done on the spindle total length. The maximum issible load is the nominal of that size. b) The maximum issible load is the nominal of that size c) The verification at buckling must be done on half spindle total length considering the structure constraints. The maximum issible load is the half the nominal of that size. The overall dimension C1 has to be considered on both faces and numerically correspond to the values reported in pag. 62-63 schemes. Incompatibility: TP models – size 183, 9010, 10012, 12014, 14014, 16016, 20018, 25022 a)

FD fast disassembling TPR model In some applications (very long spindles, fast maintenance, rational expeditions) can be a good idea to disassemble a TPR spindle from the jack body without long and expansive operations like le disassembling of the elastic pins between spindle and wheel. In this case it’s possible to offer a solution in which spindle is made by two crops ending with two TF terminals (look at page 64) connected by bolts. Disassembling them spindle will become two components easy to re-assemble. Obviously the nut stroke cannot extend over the double TF, and this cause a major overall axial dimension, as shown in the drawing below. A spigot on the terminals guarantees axial alignment between the crops after reassembling. The overall dimensions are shown in the table below. Incompatibility: model TP – size 183, 9010, 10012, 12014, 14014, 16016, 20018, 25022

GV Viton® seals Due to the friction phenomena, rotating components and the seals on which they slide can locally reach high temperatures. If the previewed ones over 80 °C, commercial seals constitutive materials can lose their properties and damage themselves. In these cases, on demand, it’s possible to use seals realized in Viton®, a special material able to be stable, up to continuous temperatures of 200 °C, to brittling and hardening phenomena.

NIPLOY treatment For applications in oxidizing environments, it is possible to protect some screw jack components, which do not undergo any sliding, by means of a chemical nickel treatment, the so-called Niploy. It creates a non permanent surface coating on casings, covers, bushings, end fittings, and on the protruding shafts of the worm screw. The threaded spindle cannot undergo this treatment.

For applications where a permanent resistance to oxidizing is necessary, it is possible to supply the components in stainless steel. Sizes 204, 306 and 407 foresee a model in AISI 316, as a standard production, for all components: threaded spindles, covers, bushings, casings, end fittings and motor flanges; the only exception is the worm screw, which, on demand, undergoes a Niploy treatment in case of protrusions. The X series can be applied in the sea environment without any oxidizing problems. It is possible to supply all the remaining sizes in AISI 304 or 316 steel as special components. For further informations see pages 226-229.

AM Over-size spindle This construction solution, which is very useful in case a compression static load is very different from its corresponding dynamic load, consists of mounting on the screw jack a threaded spindle having the higher size. This model can be applied to TP models for sizes 183, 204, 306, and to TPR models for sizes between 183 and 559; it cannot be applied to the ALEPH series. If the model has an over-size spindle the Euler test should be performed on the higher size. It’s important the load and power capacity is related to jack body size, and not to the spindle diameter. The overall dimensions are indicated in the previous page table.
