RADIAL BALL BEARING Russian patent published in 2014 - IPC F16C19/04 F16C39/02 F16C41/02 F16C33/58 

FIELD: machine building.

SUBSTANCE: radial ball bearing comprises an inner ring (7), an outer fixed ring (6), balls of larger diameter (1, 2, 3) and balls of smaller diameter (4, 5) which are alternately set in circular grooves. At the face end of the fixed ring (6) the direction of radial load (R) affecting the ball bearing is fixed, provided with the said direction the rigidity of the fixed ring (6) in the contact with a ball (1) in the radial load (R) action direction is reduced by maximum cos B times, where B stands for the central angle between the balls of larger diameter (1, 2, 3); the fixed ring (6) rigidity is reduced due to lowering (8) on the fixed ring cylindrical surface thus contact pressure in the balls is redistributed, and provided with the said direction the ball (1) contact spot with the fixed ring (6) in the direction (R) is increased due to the increased length of the contact line (B) of the ball (1) with the fixed ring (6).

EFFECT: longer service life of a radial ball bearing in a product.
