ROLLER ANTIFRICTION BEARING Russian patent published in 2014 - IPC F16C19/22 F16C19/26 F16C33/34 F16C33/58 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. A roller antifriction bearing consists of external (1) and internal (2) rings with cylindrical raceways having shoulders, rolling members in the form of rollers (3), a separator for separation of the rollers (3). The ends of the rollers (3) are of a spherical shape with the sphere radius being equal to the roller (3) radius. Each of the raceway sides opposite to each other is fitted with the shoulders (4) made in respect to the vertical bearing axis, the raceway profile is mating the profile of the rollers (3). Each raceway is additionally fitted with a projection (5) made on the side opposite to the shoulder (5) and mating the profile of the rollers (3) as well. The projection (5) height is defined by the possibility of assembling the bearing, in particular, due to the outer ring (1) heating.

EFFECT: reduced moment of friction created at the bearing operation, and an increased load-carrying ability of the bearing in the axial direction.
