Simulation Research of Tooth Break Faults of Planetary Gearboxes Considering the Transmission Path
Tooth break is a common fault which always occurs in the planetary gearboxes
and when it occurs
due to the influence of transmission path
the vibration signal collected by the sensor becomes complicated
which brings difficulties to fault diagnosis. Thus
in order to study the influence of transmission path on spectrum structure of planetary gearboxes with tooth break fault
the rigid-flexible coupling models with no fault
sun gear tooth break fault
planet gear tooth break fault and ring gear tooth break fault of planetary gearboxes are established on Adams
and the vibration signals of the box body are extracted and analyzed by simulation. The simulation results show that: in the time-domain
the change of the path will have an obvious amplitude modulation on the vibration signal which is measured at a fixed point of the box. What's more
in the spectrum diagram
the two sides of the meshing frequency will also produce side bands composed of different frequencies.This study can provide basis and reference for fault diagnosis of planetary gearboxes in the future.
