Abstract

The invention discloses an electric automobile driving motor bearing high temperature high speed high load endurance testing apparatus which includes: a workbench; a heater box which is arranged on the workbench and is provided therein with a testing shaft which is provided with at least one to-be-tested deep groove ball bearing thereon; a driving apparatus which can drive the testing shaft to rotate and is arranged on one side of the heater box; an axial loading apparatus which can supply axial load to the to-be-tested deep groove ball bearing and is arranged on the other side of the heater box; a radial loading apparatus which supplies radial load to the to-be-tested deep groove ball bearing and is arranged above the heater box; a PLC control system which can control the heater box and the driving apparatus to work. According to the invention, the whole testing process is simple, can simulate working environment inside the electric automobile driving motor, can accurately test technical parameters of the deep groove ball bearing, and provide great convenient to operation workers.

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...
