The cardan joint 42 takes up the bearing bias through its high axial rigidity.

On rolling bearing products, bearing proload can be adjusted.

The bearing preload can be transferred directly onto the bearing via the seal.

The precision is very high because of the pretension of the bearing.

Low thermal expansion helps maintain consistent bearing preload and stiffness at high speeds.

In the type of wheel bearing selected, the pretension of the bearing is set by the tensioning bolt 29 .

The pretension of the bearing is determined by the production steps and the shape of the beading 39 .

Analogously, the forces for providing the bearing bias are transmitted by the screws 44 and 50 through cardan joints 48 and 54 to the inner ball bearing races 18 and 28.

As a result, because of the given bearing prestress, a correspondingly minimal bending moment is exerted on the piston rod which, in turn, permits a reduction of the rod diameter.

The axial length of the inner race ring can also be such that, upon the required bearing preloading being reached, the two end plates bear on the end faces of such ring.

On the test stand, in parallel with the test runs, clamping tests were carried out on the thin-walled bearings to investigate the loss of bearing prestress (variation in radial pressure) and the free spread loss, since these values may be directly compared with the test results relating to conventional bearing shells (wall thicknesses 1.4 and 1.8 mm, same bearing geometry).

It has been shown that the bearing prestress (radial pressure) diminishes in linear manner as the temperature increases, wherein the gradient of the straight lines is not very steep and is the same for all bearing dimensions.

Of course, once the bearing preload and the crown wheel-pinion mounting distance have been successfully adjusted, the bearing sleeves 27 and 28 can be secured in known manner against unintentional rotation.

For the complex calculation of the required bearing preload, GMN provides software solutions that deliver reliable preload results, using our long-term practical experience.

With rigid bearing preload, specified bearing pairs in O, X or tandem arrangements offer an effective, cost-effective and technical solution for many applications.

The Timken® Hydra-Rib™ bearing is a tapered roller design available in any class of precision to maintain optimum spindle system preload.

This results in a particularly short tolerance chain for the bearing prestressing which is defined substantially by the length of the stator along the axis and the spacing of contact shoulders for ball bearings on a shaft of the rotor.

Moreover, it is provided that the bearing bias is always maintained in the same direction, so that hopping of the bearing elasticity is avoided.

The use of an actuating element, for example in the form of an actuator, for targeted torque-dependent bearing pretension reduces the pretension in the partial load region and improves the degree of efficiency, but has the disadvantages already described.

This torque-dependent bearing tensioning reduces the power losses of the bearing, in particular in low and average torque ranges, whereby this results in a further reduction of the energy requirement for the operation of the motor vehicle.

There is therefore provided in a surprisingly simple manner a bearing arrangement which consists of individual components, some of which are known per se, and is not only slender or axially short but, in addition, allows simple and exact setting of the bearing prestress in a completely novel manner.

The change in the preload within an operating temperature range is undesired since, in the event of an enlargement of the bearing play, the results of the measurement become inaccurate and since, in the case of too high a bearing preload, the increased friction leads to a greater power demand, which in particular is critical for battery operated, mobile measuring devices with a limited power capacity.

Despite the fixed-fixed bearing principle, the bearing preload, once set, is therefore constant over a very wide temperature range (between very low negative temperatures up to very high temperatures) and is therefore thermally neutral.

The above-described haptic behavior of the positioning device can also be obtained via a manipulative change in the bearing preloading (loading of/removal of load from the bearing) by means of the magnetic axial force which is influenceable and generated during operation of the axial flow motor.

In any case the relative rotation of the shaft or the regions of the shaft and thus the relative rotation of the drive part with respect to the bearing ring Can be implemented through the control part and the actuating part into an axial force impacting the bearing ring of the shaft and thus into an axial movement thereof, whereby the torque-dependent bearing tension in accordance with requirements is thus realized.

For this purpose a bearing tension is generally necessary which, as described, is achieved through the mounting device according to the invention only when needed in a simple manner.

With the mounting arrangement 10 a play-free torque-dependent transfer of axial forces, thus forces in axial direction of the shaft 14 according to the direction arrow 44, is achieved by a bearing tensioning of the mounting device 10 or the conical roller bearings 22 and 24 in axial direction.
