Roller bearing retainer

Abstract

The invention discloses a roller bearing retainer, and relates to the technical field of roller bearings. The roller bearing retainer comprises a retainer main body as well as circular ring shaped retainer baffle plates which are connected to the two sides of the retainer main body, and are matched with the shape of the retainer main body, wherein through holes which communicate with pocket holesare formed in positions, corresponding to the pocket holes, in two side end surfaces of the retainer main body; a bulged column which is matched with each through hole is arranged on the correspondingposition of each retainer baffle plate; the retainer main body and the retainer baffle plates are connected through the bulged columns and the through holes; supporting balls and springs are outwardssequentially arranged in the through holes in the two sides of a roller bearing from the roller bearing; and the supporting balls abut against in concave surfaces at the two ends of the roller bearing. The roller bearing retainer has the beneficial effects that a roller bearing adopting the structure of the retainer is simple in structure, is small in impact load, supplements lubricating oil conveniently, and has a lubricating oil self-supplementing function in an operation process.

Description

technical field [0001] The invention belongs to the technical field of roller bearings, and in particular relates to a roller bearing cage. Background technique [0002] Roller bearings are one of the more commonly used components in large production equipment. It mainly includes outer ring, inner ring, roller and cage. The cover and seat of the commonly used copper alloy solid cage are connected by rivets, the verticality of the rivet holes is difficult to guarantee, and the balance will be affected during high-speed operation. During the operation of the roller bearing, the pocket and the roller are in surface contact, the gap is small, the collision force between the roller and the cage is large, and the contact surface lubricating oil is insufficient, which will cause serious wear of the cage, increase the temperature of the bearing, and cause vibration And noise, causing the bearing life to be seriously affected. Those skilled in the art have been looking for feasibl...
