Gearbox Fault Simulation Experiment Platform System

Mechanical vibration analysis and fault simulation test bench is a platform for simulating various faults of mechanical moving components, conducting vibration testing, diagnosis, and analysis. Its main functions are: gear fault simulation: by replacing defective gears, various gear faults can be simulated (providing three spare gears, which can be used to process three types of gear faults such as cracks, broken teeth, and wear according to requirements).

（1） Test bench indicators

Function:

（1) Can simulate faults such as tooth breakage, cracks, and wear in helical gearboxes and planetary gearboxes. Among them, there are three types of faulty gears: planetary gear with broken teeth, cracks, and wear, and sun gear with broken teeth, cracks, and wear; The helical gearbox is equipped with three types of faulty gears: broken teeth, cracks, and wear.

（2) Variable speed simulation of fault characteristics under different speed conditions, with a speed range of 75-1450RPM.
