Intr

oduc

tion ROLLVIS satellite roller screws are used to transform rotary movements

into linear movements and vice versa. The bearing elements are threaded

rollers between the screw and the nut. The high number of points of contact

enables satellite roller screws to support very heavy loads.

The ROLLVIS manufacturing programme comprises satellite roller screws

without roller recycling (types RV and BRV) and with roller recycling (type RVR),

in a range of accuracy classes.

The ROLLVIS range also includes other types such as the reverse roller screw

(type RVI) and the differential screw (type RVD).

Satellite roller screws compared to ball screws

The satellite roller screw is similar to the ball screw with the difference that the load transfer elements are threaded rollers.

The main advantage of satellite roller screws is that they have a high number of points of contact to support the load.

Load capacity and lifespan The main advantage of roller screws compared to ball screws is that their admissible static and dynamic load capacities are higher.

The bearing function is ensured by threaded rollers instead of balls and the load is spread over a higher number of points of contact.

Satellite roller screws like ball screws use Hertz’s law. The admissible Hertz pressure is the same for satellite roller screws and ball screws. Satellite roller screws thus have a static load 3 times greater than that of ball screws and their lifespan is 15 times longer.

Speed & acceleration Satellite roller screws can rotate much faster and support much greater acceleration.

RV and BRV satellite roller screws are designed so that the rollers are not recycled. This means the mechanism can support twice the rotation speed of a ball screw. Acceleration can reach up to 3g.

Lead & pitch Planetary roller screw can be achieved with smaller leads compared to ball screws. As the lead is a function of the pitch of the planetary roller screw, the lead can be very small (0.5mm and even less).Planetary roller screws can be achieved with entire or real numbers (i.e. lead of 3.32mm per revolution), which avoid reduction gears. This is an advantage compared to ball screws. The lead can be chosen and realised without any geometrical changes of both the screw shaft and the nut body, which allows updates with minor changes.In a ball screw the lead is limited by the dimension (OD) of the bearing ball, which is a standard feature.

Rigidity & strength The many points of contact give a satellite roller screw greater rigidity and shock tolerance than a ball screw.

Types of roller screws

RV et BRV

RVR

The main elements of RV and BRV satellite roller screws are the screw, the nut and satellite rollers.

The screw has a multiple-start thread. The angle between the fl anks is 90° and the profi le is triangular. The nut has an internal thread identical to that of the screw. The rollers have a single-start thread with an angle the same as that of the nut. This ensures there is no axial movement between the nut and the rollers. The rollers do not therefore need to be recycled.

The fl anks of the roller thread are convex. At each end of the rollers there is a cylindrical pivot and gear teeth. The pivots are mounted in the holes of the end rings, thus ensuring the rollers are equidistant. The end rings are fl oated in the nut body and axially secured with circlips.

The gear teeth engage in gear wheels fi xed in the nut. This guides the rollers parallel to the axis to ensure perfect functioning.

RVR satellite roller screws have very fi ne threads and are used when very great positioning accuracy is required along with high rigidity and load-carrying capacity.

The main elements of RVR satellite roller screws are the screw, the nut and the rollers which are guided and maintained at the correct distance in a cage.

The screw has a single- or two-start thread with a triangu-lar profi le. The angle between the fl anks is 90°. The nut has the same internal thread as the screw. The rollers are not threaded but have grooves perpendicular to the screw axis. The distance between the grooves matches the exposed thread of the screw and nut. The fl anks are convex and the angle between them is 90°.

When the screw or nut rotates, the rollers are axially displaced in the nut. After a complete revolution, each roller is returned to its initial position by two cams at the end of each nut. They can be recycled this way because there is a groove the length of the nut.

The cage pockets are slightly longer than the rollers to enable them to move axially within the nut.

Types of roller screws ( ctd.)

RVI

RVI satellite roller screws work on the same principle as RV and BRV screws except that their nut system is reversed.

This means the rollers themselves rotate around the screw (instead of the nut in RV and BRV screws) and move axially within the nut.

Apart from the screw threading where the rollers orbit, the journal is smooth and can have a special shape (e.g.: antirotation).

The nut is threaded along its entire length and is much longer than on RV and BRV screws. It governs the overall travel of the complete screw and therefore limits it if needed.

The RVD differential screw is actually a variant of the RV and BRV screws.

Its components, expertly calculated and adjusted, are used to produce extremely fi ne threads (less than 0.02 mm).

The movement of the rollers in this somewhat complex mechanism does however prevent a wide range of travel.

The nuts are larger than on the RV and BRV types.

Geometry

Nut geometry and shape Standard satellite roller screws are available with 3 nut designs:

single nut (ES) split nut (EF) double nut (ED)

Single nuts have low axial backlash of 0.01 to 0.03 mm. The split cylindrical nut is preloaded by clamping the two halves of the nut in a housing. A precision spacer ring is mounted between the two halves to maintain the required level of preloading. Split nuts with a fl ange at one end have a spacer ring designed to hold the halves apart. The halves are aligned by a parallel key. Double nuts are preloaded in the same way as split nuts.

SINGLE NUTS: Nuts in one piece with axial backlash Wipers (if requested by the customer)

SPLIT NUTS: Nuts in two pieces, preloaded, without backlash Same dimensions as single nuts Reduced load capacities Wipers (if requested by the customer)

DOUBLE NUTS: Two single nuts, preloaded, without backlash Same load capacities as single nuts About twice as long as single nuts Wipers (if requested by the customer)

Preloading

FV

F1 F2

Preloaded nuts are used to eliminate backlash and increase rigidity.

Preloading should be carefully calculated to achieve the highest rate of effi ciency and the longest possible lifespan (see fi gure above).

For preloaded nuts, in addition to the individual loads F1…Fn, preload Fv must also be taken into account to determine the mean load Fm. This yields new individual loads F1v…Fnv.

If for example an absence of backlash is required for all operational loads, preload Fv must be selected according to the maximum load Fmax.

If a satellite roller screw only needs to be backlash-free for a specifi c load, preload Fv should be selected according to the corresponding load Fn.

Unless the customer otherwise requests, split and double nuts are preloaded in the standard version to a maximum of 5% of the dynamic load capacity.

Resulting load depending on preload Fv

An axial load on a preloaded nut system increases the load of one of the halves and relieves the other from the preloading force. The resulting load can be estimated by the following equations:

Loaded half of nut:

Fnv(1) = Fv + 0,65 . Fn [N] if Fn < 2,83 . Fv [N]

Fnv(1) = Fn [N] if Fn ≥ 2,83 . Fv [N]

Relieved half of nut:

Fnv(2) = Fv - 0,35 . Fn [N] if Fn < 2,83 . Fv [N]

Fnv(2) = 0 [N] if Fn ≥ 2,83 . Fv [N]

Permissible buckling force Fknzul at rotation speed n = 0 Permissible buckling force can be calculated by the following formula:

Rotation speed

Permissible rotation speed and axial load Satellite roller screws are restricted by the internal confi guration of the nut, the bearings at the end of the screw and the critical number of revolutions nkr due to fl exural vibration.

The value of the permissible speed applied can be:

RV : d0 . n ≤ 140’000RVR : d0 . n ≤ 32’000

Critical speed nkr with axial load Fn = 0 Critical speed is infl uenced by the axial load. It can be calculated on request for every satellite roller screw confi guration.

When the correct screw end bearings are chosen, their maximum speed will have no effect on the desired speed. All that needs to be determined is the critical speed nkr for fl exural vibration.

The critical speed nkr for fl exural vibration can be calculated by the formula below. The correction factor fkr depends on the type of bearing and the clamping conditions (fi gure above).

The calculation is based on the assumption that satellite roller screw nuts provide no guidance and the bearings at the screw end are considered rigid in the radial direction.

Lubrication

As a general rule, the same lubricants are used for satellite roller screws as for roller bearings, i.e. either oil or grease. The type of lubricant used mostly depends on operating and maintenance conditions. Unless the customer explicitly instructs otherwise, standard Rollvis grease is applied at the factory.

Circulating mineral oils with EP additives to enhance resistance to aging and corrosion in compliance with CL based on DIN 51517, part 2, are especially suitable for the lubrication of satellite roller screws. Speed, ambient temperature and operating temperature are determining factors in the choice of viscosity.

The amount of oil required depends on the screw diameter, the number of supporting rollers and the amount of heat to dissipate. 1 cm3/h (for small screw diameters) to 30 cm3/h (for large screw diameters) can be used as reference values.

The shortest possible lubrication intervals (…5 minutes) are recommended for high loads and longer intervals (5 minutes to 1 hr) for low loads. Automatic lubrication is recommended for high loads and speeds.

For immersion lubrication, the oil level should be such that the bottommost roller is completely submerged in the oil. The amount of oil and the oil-change intervals depend on the loading and installation.

The viscosity of the oil should be chosen to enable an adequate fi lm of lubricant to form on the contact surfaces.

Figure a shows the operating viscosity νκ to achieve for the mean speed of the satellite roller screw and screw diameter.

Viscosity νκ ensures a state of lubrication to fulfi l the nominal lifespan provided the lubrication system is free of foreign bodies.

Nominal viscosity can be calculated on the basis of viscosity νκ with the viscosity-temperature diagram (diagram ν-t, fi gure b) and the operating temperature. Nominal viscosity is the viscosity of oil at 40°C. Viscosity classes ISO VG (DIN 51519) are plotted in diagram ν-t.

Figure a shows the nominal diameters of RV satellite roller screws. The diameters of RVR satellite roller screws are slightly different. The requisite operating viscosity values can be obtained by interpolation.

Intermediate values can be obtained from the steps. These must be rounded up to the nearest viscosity value.

The operating temperature must be known or estimated to calculate nominal viscosity. The operating temperature must be measured on the nut after stabilisation. A suitable oil can be found in oil suppliers’ lists with the nominal viscosity at 40°C. In general, an operating temperature of 30°C can be taken as a basis for selecting a lubricant.

Example: Satellite roller screw RV 39 x 10Mean operating speed: nm = 1400 min-1

Operating temperature (estimated): t = 25 °C

In fi gure a, for a number of revolutions nm = 1400 min-1 and a nominal diameter of 39mm, the nominal viscosity is νκ= 33 mm2/s. In diagram ν-t (fi gure b), the 25°C temperature and 34 mm2/s viscosity lines intersect between ISO VG 15 and ISO VG 22. The oil to choose will be in viscosity class VG 22.

A suitable CLP (DIN 51517) or HLP (DIN 51525) oil can be selected from this class.

Oil lubrication

Grease lubrication The best grease lubricants to use are KP (DIN 51825, part 3) with a consistency factor of 2.Lubrication intervals depend on the screw arrangement, size and operating conditions. Rollvis can provide recommendations for any type of application.

Handling advice

Assembly If possible, the nut and screw should not be dismantled. However, should this be necessary, an assembly sleeve must be used.External diameter d3 of assembly sleeve: 0

d3 = d2 - 0,05 (d2 = screw core diameter)

Handling Please read the following handling instructions carefully.

To ensure optimal operation and a long lifespan for satellite roller screws, the following points must be scrupulously complied with.

If in doubt, please contact Rollvis.

Screw assembly Montage de la vis The following points must be followed when assembling the screw: 1 • Align the screw and slide guideways axially parallel.2 • Fix the nut in housing.3 • Run the nut along the entire length of the thread and check the screw

for ease of movement

RV screws always have a multiple-start thread. If the friction torque is different after the nut is reassembled, the nut must be taken off again and refi tted on the next thread start until friction torque is correct!

CAUTION

Satellite roller screws are greased prior to shipment (unless oil lubrication is requested).

Do not remove this grease. Only use this type of grease for relubrication.

Lubrication

Handle screws with care: do not drop them or damage the thread. Transport

Do not unscrew the nut (or only with an assembly sleeve).Carefully align satellite roller screws parallel to the guideways.Alignment errors will damage satellite roller screws.

Installation

Only remove satellite roller screws from their original packing just before installation.

Storage

Avoid applying radial forces to the nut. Bending
