Deep groove ball bearing retainer and deep groove ball bearing

Abstract

The invention discloses a deep groove ball bearing retainer and a deep groove ball bearing. The deep groove ball bearing comprises a bearing inner ring, a bearing outer ring, rolling bodies and the retainer (100); the retainer (100) is located between the bearing inner ring and the bearing outer ring, and the rolling bodies are installed on the retainer (100); the retainer (100) comprises a retainer body, pockets (1) and ring slots (2); the pockets (1) are uniformly arranged on the retainer body, and rolling bodies are installed in the pockets (1); and the ring slots (2) are arranged in the pockets (1), and the ring slots are internally provided with lubricating oil. The retainer (100) is good in lubricating effect, the temperatures of the rolling bodies and wear to the retainer (100) can be lowered, the retainer is not liable to damage, and the service life of the retainer is prolonged.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a deep groove ball bearing cage and a deep groove ball bearing. Background technique [0002] The cage is an important part of deep groove ball bearings, which is used to wrap the rolling elements to isolate the rolling elements. Due to the friction between the rolling elements and the cage during the working process of the bearing, a large amount of heat is generated; in the prior art, the lubrication methods for the bearing are mostly drip lubrication, circulating oil lubrication, etc. It cannot reach the rolling elements quickly and effectively, so the lubrication effect is not good. In this way, the cage of the deep groove ball bearing will be worn by the rolling elements and easily damaged, thereby reducing the service life of the cage. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, an object of the present invention is to pr...

Problems solved by technology

Due to the friction between the rolling elements and the cage during the working process of the bearing, a large amount of heat is generated; in the prior art, the lubrication methods for the bearing are mostly drip lubrication, circulating oil lubrication, etc. It cannot reach the rolling elements quickly and effectively, resulting in poor lubrication effect. In this way, the cage of the deep groove ball bearing will be worn by the rolling elements and easily damaged, thereby reducing the service life of the cage
