RADIAL ROLLER BEARING AND METHOD FOR ITS INSTALLATION IN BEARING ASSEMBLY Russian patent published in 2013 - IPC F16C19/22 F16C33/58 

FIELD: machine building.

SUBSTANCE: radial roller bearing includes external (1) and internal (2) rings and rollers (3) being rolling elements, which are located between them. On one of rings (1 or 2) of the bearing there formed are local sections with changed bulk weight, which are uniformly distributed along the ring and the number of which can be different, for example three or four. Local sections can be formed by removal of the ring material or its growth. Besides, an erection method of a radial roller bearing in the bearing assembly is proposed, which consists in the fact that rings (1, 2) are installed on mounting seats of the bearing assembly supports. Ring (1 or 2) of the bearing, on which local sections with changed bulk weight are formed, is installed on the mounting seat of the bearing assembly element having the possibility of being rotated with a gap relative to it freely in axial direction and fixed relative to that element against being turned. The other ring (2 or 1) is installed on its mounting seat of the bearing assembly with pre-load.

EFFECT: development of a bearing design and providing its installation in a bearing assembly so that in all bearing operating modes there can be provided constant contact of some part of rollers with rings, which will allow excluding slipping of rollers relative to rings.
