1. The basic structure of the test bench

The test bench uses a motor, a dynamic torque sensor, a ZDY-80 parallel shaft gearbox for deceleration, and a magnetic powder brake as the experimental load to form a complete fault simulation system. The experimental load can be changed by adjusting the excitation current of the magnetic powder brake. Supporting data acquisition system and related software, acceleration sensor, etc. can realize the vibration, noise, torque and speed signal measurement of normal and faulty gears.


2. Experimental research content

Motor fault research: With different types of faulty motors and current and voltage sensors, it is possible to study motor rotor unbalance faults, motor bearing faults, motor rotor broken bar faults, etc.;

Research on the failure mechanism of parallel shaft gearboxes: different failure forms of straight teeth and helical teeth, such as pitting, wear, cracks, broken teeth, missing teeth and other common failures; different failure forms can also be customized according to requirements;

Rolling bearing fault research: different fault forms of gearbox support bearings, such as pitting, cracks, wear, cage fracture, etc.;

Simulation of different working conditions: gear characteristics under the state of motor speed up and down, gear characteristics under different load conditions, etc.
