ECCENTRIC FRICTIONLESS BEARING Russian patent published in 2009 - IPC F16C27/00 F16C25/06 F16H13/08 

FIELD: machine building.

SUBSTANCE: invention is related to machine building, namely to frictionless bearings, and may be used in mechanisms that transform rotary motion into oscillating one. Eccentric frictionless bearing comprises external ring that is eccentric to shaft, three rolling elements of different diameter that interact with shaft and external ring, two separating rollers installed between rolling elements, and additional ring that embraces separating rollers. Besides separating rollers on both sides are adjacent to the largest rolling element. Additional ring rests on shaft and separating rollers. At that shaft, external ring and rolling elements or one of them are equipped with gear rims that are engaged.

EFFECT: simplification of drive design and manufacture technology, expansion of bearing kinematic resources.
