[0024] Example 1
[0025] The shaft test device of this embodiment that can simultaneously apply two-stage tension and torsion composite load, its structure is as attached figure 1 Attached Image 6 As shown, the tested shaft is the turbine shaft of a certain type of aero engine. The specific structure of this test device is as follows.
[0026] 1. The overall structure of this test device is attached figure 1 As shown, it is composed of a device frame, a first-stage tensile torsion load loading module, a second-stage tensile torsional load loading module, a reverse torque load loading module, and a test shaft positioning device installed on the rack. The test device is a vertical structure as a whole. The torque loading cylinder 13 in the first-stage tensile-torsional load loading module and the second-stage tensile-torsional load loading module, and the return spring assembly 17 in the anti-torque load loading module are all set horizontally. The axial force loading cylinders 1...
