ANTIFRICTION BEARING Russian patent published in 2004 - IPC

FIELD: mechanical engineering, instrument engineering.

SUBSTANCE: invention can be used in all industries. Proposed antifriction bearing contains solids of revolution-rollers which are made two-step. Larger diameter of step rolls only over path of bearing outer race, and smaller diameter of roller step, made at least with two sections, rolls only along path of bearing inner race at constant and equal velocity of rotation. Solids of revolution-rollers can be made two-step beveled. Solids of revolution can be provided with rings interacting with paths of bearing races and rolling over diameters of stepped roller. Rings can be made flexible, three-support type.

EFFECT: increased velocity of rotation, reduced value of elastic hysteresis in zone of contact of solids of revolution and bearing races, provision of damping of load fluctuations.
