Gearbox Failures In Ball Mills

The fatigue in the gears induces the formation of cracks in the root of thegeartooth which propagates with each rotational cycle of the gear and ultimately leads to the failure of thegeartooth pitting this is a major cause ofgear failureaccounting for nearly 60 of thegear failurespitting is the formation of craters on thegeartooth surface
