Abstract

FIELD: machine building.
SUBSTANCE: method of unloading racers from effect of centrifugal forces consists in generation of forces effecting rolling bodies in direction of rotation axis wherein external racer is made of two parts installed with gap. Said forces are generated by means of holding down two parts of the racer to rolling elements and by bringing their external rolling paths to contact with rolling elements at assembly of the bearing. Here is also disclosed design of the rolling bearing for implementation of the said method. According to the second version of unloading the said forces are generated by pressing the rolling elements with at least two racers and by bringing racers external rolling paths into contact with rolling elements. At least one of the said racers functions by being held down to the rolling elements, while another racer is made as a flexible ring with a rolling path, rotates freely and is installed with tightness relative to the rolling elements holding them down to the direction of rotation axis. Here is also disclosed design of the rolling bearing for implementation of the said method according to the second version.
EFFECT: rolling bearing of high processability, with reduced wear and operation expenditures.
