Abstract

The present invention discloses a fault diagnosis and life testing machine for a flexible precision thin-wall bearing (16), including a rack, and an axial loading device, a main driving device, a bearing mounting device, a clamping tooling, a data acquisition device, a hydraulic and a pneumatic auxiliary device which are provided on the rack. The main driving device is connected to a rear side of the axial loading device, and the clamping tooling is arranged at a front side of the axial loading device, for clamping the thin-wall bearing (16) onto the bearing mounting device. The data acquisition device is arranged in the axial loading device and at a side of the rack, the hydraulic and pneumatic auxiliary device is arranged at a side of the rack, and the axial loading device and the main driving device are connected by a pipeline. This testing machine can apply dynamic and static loads to the precision flexible thin-wall bearing (16), can realize measurement of a bearing vibration, a bearing temperature, a bearing rotation progress and a rotation speed, and has advantages such as clever structure, perfect test function and relatively high test accuracy, safe and reliable detection …
