AI Technical Summary
Existing bearing testing equipment cannot realistically simulate the complex stress conditions of aero-engine propeller shaft bearings in actual applications, resulting in poor testing accuracy.
A novel propeller shaft bearing test loading device is designed, comprising a housing, multiple first bearing seats, a test shaft, a first radial force load loading component, and a simulated load loading unit. Radial and axial forces are applied through the test shaft to simulate the complex working conditions of the intermediate gear on the propeller shaft, forming bending moment force and realistically simulating the stress condition of the bearing.
It improves the accuracy of bearing testing, ensures test quality, and can realistically simulate the stress conditions of bearings under actual working conditions, thereby improving the accuracy and stability of the test.
