ROLLER BEARING Russian patent published in 2005 - IPC

FIELD: machinery engineering, particularly roller bearings.

SUBSTANCE: roller bearing comprises racers, rolling members installed in-between and retainer shaped as ring with depressions for rolling member receiving and having bridges between the depressions. Retainer also has side bridges with extensions bent at an angle to radial plane. Apexes of extensions have roughness comparable with that of working rolling member surfaces and face axes of rolling member rotation. The apexes are shaped and dimensioned to mate axial orifices formed in rolling members to bring the apexes into cooperation with the orifices. Distance between the apexes is less than rolling member dimension. Bridges between retainer depressions are spaced equal or greater distance from axis of roller bearing rotation.

EFFECT: reduced rotational resistance.
