Vibration analysis and identification of faults in a spur geared rotor system integrated with active magnetic bearings

Abstract

Gearbox is widely used in industrial transportation and military applications The gearbox vibrations and noise caused by variation of contact forces often causes failure in the components of gearbox which are then transmitted to the surrounding structures The sources of error between the mating gears while in the operation are the gear mesh deformation transmission error and runout resulting in dynamic forces excessive vibration and noise To avoid any undesirable effect on the gear pai...
