According to the scheme, the bearing is sleeved on the workpiece, the bearing inner ring is matched with the workpiece for positioning, the bearing stop retainer is sleeved on the workpiece, the bearing stop retainer is matched with the bearing inner ring for limiting and preventing dust, the whole bearing is limited, the bearing is prevented from moving during operation, and the problem that in the prior art, the bearing moves during operation and has poor dust-proof effect is solved. The bearing has the advantages of simple design, convenient operation and improved running reliability.
Description
Technical Field
The present utility model relates to the field of bearing parts, and more particularly to a bearing retainer.
Background
In order to prevent the bearing from moving during operation to play a stationary role, not a brake. The bearing runs in various environments, particularly in severe environments with more wind and sand working conditions, foreign matters easily enter the roller path through gaps between the inner ring and the outer ring of the bearing, so that the bearing is damaged in running.
In order to solve the above problems, there is a need for an improved bearing retainer that better ensures safe operation of the bearing. However, in the prior art, referring to fig. 3, the bearing is stopped with a gap, and in this stopping manner, the bearing is easy to move in the running process, and foreign matters easily enter the raceway through the gap between the inner ring and the outer ring of the bearing, so that the bearing is damaged in the running process.
