ABSTRACT
In designing the gear, several holes are often slot on the web in order to lose weight. In the process of gear meshing, the single teeth meshing and double teeth meshing is conducted alternatively. The transfer path of vibration is tooth surface → lightning hole → axle → bearing → bearing pedestal → gearbox. Filling particles to the lightning hole can effectively reduce the vibration, since the lightning hole is closest to the vibration source and it is a vital place of vibration transfer.
