q:what are the common faults and troubleshooting methods

During the transmission of the torque, the gears may break off the gear teeth, pit the surface of the teeth, and treat the tooth surface. Mechanical faults such as wear and tooth surface wear cause gear failures to be as follows: a. Short-term overload or shock load, repeated fatigue caused by bending fracture; b

Fatigue particles from the gear pitch line have similar characteristics to rolling bearing fatigue particles. The particles may have a major dimension to thickness ratio between 4:1 and 10:1. The chunkier particles result from tensile stresses on the gear surface causing fatigue cracks to propagate deeper into the gear tooth prior to pitting
