Description

technical field

[0001] The invention relates to the technical field of durability testing devices, in particular to a high-temperature, high-speed, high-load durability testing device for electric vehicle drive motor bearings. Background technique

[0002] Deep groove ball bearings used in electric vehicle drive motors need to pass high-temperature, high-speed, and high-load tests after production is completed, and they can be used for a long time only after passing the test.

[0003] However, in the prior art, the overall structure of the durability test device used to test the deep groove ball bearings of electric vehicle drive motors is relatively complicated, and the entire testing process is relatively cumbersome. It is difficult to simulate the working environment of electric vehicle drive motors, and it is difficult to test the deep groove. The real technical parameters of the ball bearing have brought great inconvenience to the operator.

[0004] However, in view of...
