Description

Compression-elastic axial rolling bearing arrangement

Di © innovation has a particular worm = press-developed Axial xtfäialageranOrdnung the subject, prevent Überbeanspruohung of the rolling elements in the elastic elements die'infolge iron Because deflections, thereby eliminating Kshtenpressungen caused ₀

It is known ^ expand between a enclosur and to arrange an axial rolling elastic elements in the form of sound spring washers or spring systems of housing washer <> su the purpose of allowing pressurized elastic setting of the bearing within certain limits to ₀ innovation subject is also such a spring system with the further task »to hold the axial roller bearing in the unloaded state under slight preload in order to seal the bearing»

To solve the task, the innovation provides that between the housing wall and the housing washer des.Axialwälzlager several spring elements sentrisoh are arranged on the bearing axis, each consisting of zx-zei there are compression springs arranged one behind the other, one of which, heavy-duty compression spring, absorbs the forces acting on the bearing elastically, while the other, light-duty Compression spring that seals the pressure bearing in the unloaded state, doho, the existing play through their bias eliminated "

The pressure pad 13 is provided with a through hole 15, which has shoulders in its head part for receiving a disk spring assembly 16 that can withstand low loads and a further pressure pad I ?. The disk spring assemblies 16 consist of four disks, which are also half directed against each other. The shaft 17 'of the pressure mushroom 17 is guided in the bore 15 of the pressure mushroom 13

The axial roller bearing, a cylindrical roller bearing with two rows of short rollers 18, which are guided in a cage, is supported with its housing washer on the pressure mushrooms 13 «17 of the spring systems from _p while its wave washer 21 is supported on the flange ring k and with the flange ring via a driving pin 22, the ring into recesses of the flange · = k and the wave washer 2 ° engaged, coupled is ₀ Di © drawing illustrates the bearing in the unloaded state, in which the bearing through the small disc spring packets 16 on the pressure Pilse 1? is tightly provided ₀ The large plate springs 11 are slightly biased, and the end face of the pressure mushrooms 13 contact the housing disc 20 of the axial rolling bearing is not "As soon as at occurring load from the shaft 1. via the inner ring of the spherical roller bearing 2 and the flange h a pressure on the Axial roller bearing is exercised ₉ , the small disk spring assemblies 16 are initially compressed and the housing washer 20 is supported on the face of the pressure mushrooms 13 from ₀ Depending on the magnitude of the pressure occurring, the disk spring assemblies © 11 are more or less loaded, but they are dimensioned so that with normal loading of the shaft 1 a plant of the housing plate 20 on Deekelring 8 did not take place when arise as a result of unilateral of shaft deflections bearing loads, these means of the spring systems are balanced, DOH _o, the housing washer 20 may vary with the degree of tfellendurchbiegung and against the action of the Feather in crookedly set so that edge pressures of individual rolling elements 18 are prevented »As soon as
