Turn, different degrees of vibration and noise problem can be produced, can not only reduce the transmission accuracy and service life of gear, and then influence
The operating accuracy of machinery and life-span, but also noise pollution can be caused, influence people's is healthy.Therefore, the vibration damping of gear
Noise reduction to improve machinery service precision, the service life of prolonged mechanical, improve people working environment in terms of all have weight
The meaning wanted.
In the last few years, the vibration noise problem of gear was increasingly protruded, such as in document (Analytical
Characterization of the Unique Properties of Planetary Gear Free Vibration) in
Mention, the noise that the gear drive of helicopter is produced has exceeded 100dB, is main noise source.In order to reduce gear structure
Gear structure is optimized vibration noise, domestic correlation scholar.Such as existing patent (Publication No.
CN204200999U a kind of phonon crystal vibration-reduction gear, is filled out by being processed on gear wheel body in multiple circular holes, circular hole disclosed in)
