| Abstract: | This paper describes the CW- series eddy current dynamometer failure and damage in the process of engine reliability testing, and identifies the damage of dynamometer deep groove ball bearing resulting in the serious wear of the bearing seat hole, according to the fault diagnosis and failure analyze, and the dynamometer can not run normally again. Testing personnel carries out a lot of work in the repairing of bearing seat hole, bearing selection, assembly gap adjustment and dynamic balancing. After the restoration, the dynamometer runs well and basically satisfies the requirements of engine reliability. |
