A transmission shaft assembly for use in a sequential test of flexible thin-walled bearings includes a power connecting member, a clamping device and a plurality of bearing mounting kits. The bearing mounting kits are located between the power connecting member and the clamping device. The clamping device penetrates a central bore of each of the bearing mounting kits and is connected to the power connecting member. The power connecting member, the clamping device and the bearing mounting kits are connected into one piece. The power connecting member includes a spindle shank and a blind rivet. The bearing mounting kit includes a bearing mounting sleeve seat, a rear retaining ring, a front retaining ring, a bearing locking bolt and a tightening nut. The clamping device includes a clamping bolt, a washer and a spring washer.

Transmission shaft assembly for use in sequential test of flexible thin-walled bearings

The present invention discloses a fault diagnosis and life testing machine for a flexible precision thin-wall bearing (), 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 () 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 (), 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 process, and highly feedback results.
