FIRST TYPE REINFORCED REDUCTION RADIAL THRUST BEARING Russian patent published in 2017 - IPC F16C19/22 F16C19/34 F16C33/36 

FIELD: machine engineering.

SUBSTANCE: reducing angular contact bearing of the first type reinforced contains an outer ring (1) with a flange on each of the two sections of the conical raceway, an inner ring (2) with a flange in the center of the conical raceway, rolling bodies arranged between them in the form of two-stage tapered rollers, and the riveting rings (6) in the form of a conical sleeve with outer flanges from one piece. The steps of the larger diameter (3) of the rollers run along the raceway of the inner ring (2), and the steps of smaller diameter (4) run along the raceway of the outer ring (1) having a groove for the passage of the larger stage (3) of the roller. The larger step (3) of the roller has a cylindrical hole (5) for mounting a smaller step (4) of the roller therein. On each of the two sections of the smaller step (4) of the rollers, a tapering smaller ring (6) with inner flanges from one piece is installed, fixing the position of the ring between the rollers and imparting additional rigidity to the ring.

EFFECT: increasing the maximum load on the known models of the second type reduction radial thrust bearings and bearings with second type radial thrust stepped rollers, increasing the limit value of the bearing reduction coefficient, increasing the bearing life, decreasing due to metal fatigue in the rollers for striving the shift of the roller steps relative to each other under the external load, eliminating the possibility of moving the rollers along its own rotation axis.
