Problems solved by technology

[0002] The electric vehicle drive system has high requirements on the speed of the bearing, which is 2-3 times the theoretical limit speed of the traditional bearing. The cage of the original high-speed bearing rubs against the outer ring due to centrifugal force during high-speed rotation, causing wear and tear on the cage. damage
Therefore, the original traditional bearings cannot meet the requirements

Abstract

The invention discloses a high-speed bearing retainer with reinforcing ribs. The high-speed bearing retainer comprises an annular frame body, wherein a plurality of retainer ball pockets are arrangedon one end face of the annular frame body at intervals, and a pocket hole is formed in each retainer ball pocket; and the high-speed bearing retainer is characterized in that reinforcing ribs are arranged on the retainer shoulders between two adjacent retainer ball pockets, and the two sides of the reinforcing ribs are integrally connected with the pocket grasping outer spherical surfaces of two adjacent retainer ball pockets correspondingly. The bearing retainer is applied to a high-speed bearing, and the running speed of the bearing can be ensured to meet the requirement.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a high-speed bearing cage with reinforcing ribs. Background technique [0002] The electric vehicle drive system has high requirements on the speed of the bearing, which is 2-3 times the theoretical limit speed of the traditional bearing. The cage of the original high-speed bearing rubs against the outer ring due to centrifugal force during high-speed rotation, causing wear and tear on the cage. damage. Therefore, the original traditional bearings cannot meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-speed bearing cage with ribs for the above-mentioned shortcomings in the application of the existing high-speed bearings in the drive system of electric vehicles, which can ensure the running speed of the bearings when used in high-speed bearings fulfil requirements. [0004] The technic...
