Rolling isolation holder

Abstract

The invention belongs to the field of mechanical parts, and especially relates to a rolling isolation holder used on a bearing. The rolling isolation holder is formed by assembling an inner auxiliary ring, an inner auxiliary ring, double gear isolation rollers, single gear isolation rollers, inner supporting rollers and outer supporting rollers. The rolling isolation holder has the following advantages: a rolling element rolls synchronous with and relative to the double gear isolation rollers and the single gear isolation rollers of the holder with friction during the high speed running work of the bearing, and the inner auxiliary rings and the outer auxiliary rings of the holder roll relative to each other with the rolling of the double gear isolation rollers and the single gear isolation rollers, so sliding friction between the holder and the rolling element in a traditional bearing becomes rolling friction, thereby the friction loss of the bearing is greatly reduced, the limit rotating speed and the work efficiency of the bearing are improved, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention belongs to the field of mechanical parts, in particular to a rolling body cage used on a bearing. Background technique [0002] Rolling bearings generally consist of inner rings, outer rings, rolling elements and cages. The main wear and consumption of bearings in high-speed operation is caused by friction, which mainly includes rolling friction and sliding friction. The main parts where sliding friction occurs are: the contact surface between the rolling element and the raceway, the contact surface between the rolling element and the pocket of the cage, between the cage and the guide rib of the ferrule, and between the end surface of the roller and the guide of the ferrule. Wait between the sides. The existence of sliding friction in rolling bearings inevitably causes wear of bearing parts. If the wear resistance of the bearing steel is poor, the rolling bearing will lose its precision prematurely due to wear, or the vibration of the ...
