Problems solved by technology

Rigid lever loading system cannot achieve combined bending and torsion dynamic loading, so it is not suitable for simulating and testing the contact fatigue wear performance of gears
Because when the gear is worn, the backlash of the test tooth will change, and the transmission will not be stable, resulting in beating

Description

technical field [0001] The invention relates to a loading device, in particular to a bending-torsion composite dynamic loading device for a closed power flow type gear contact fatigue wear tester. Background technique [0002] In the mechanical closed test bench, the loader is a key component. This is because the closed moment in the test bench is generated by the loader, and the performance of the loader directly affects the performance and technical and economic indicators of the test bench. Due to factors such as manufacturing and installation errors, deformation, and friction coefficient changes, an internal excitation is formed in the mechanically closed test bench, so that internal vibration occurs when the rigid lever loading test bench operates at high speed, which affects the stability of the load. According to statistics, the resulting error is as high as 25%. Rigid lever loading system cannot realize combined dynamic loading of bending and torsion, so it is not s...
