WIPO Patent Application WO/2019/237639

A1

Disclosed in the present invention is a transmission shaft assembly for use in a sequential test of flexible thin-walled bearings, comprising a power connecting member, a clamping device and several bearing mounting kits, wherein bearing mounting sleeves are located between the power connecting member and the clamping device, and the clamping device is connected to the power connecting member after penetrating a central hole of each bearing mounting sleeve; the power connecting member, the clamping device and the several bearing mounting kits are connected into one body, and the power connecting member comprises a spindle shank and a blind rivet; the bearing mounting kits comprise bearing mounting sleeve seats, rear retaining rings, front retaining rings, bearing locking bolts and tightening nuts; and the clamping device comprising a clamping bolt, a washer and a spring washer. The present invention is suitable for the sequential test of thin-walled bearings, may be directly matched and connected to a high-speed electric spindle, and is convenient to mount. At the same time, the use of the modular design may change the test scheme by means of increasing or decreasing the number of bearing mounting sleeves, thereby increasing the flexibility and reliability of the test.
