负载对塑料行星齿轮传动振动特性的影响

o have a further research on the vibration characteristics of plastic planetary geared system under different running condition, this paper establishes the test rig for the plastic planetary geared system. The experimental data were processed by using the spectrum analyze technique and time domain filter technique. The analytical results show that the spectra of the plastic planetary geared system are comprised of 1 × GMF spectra and its harmonics spectra, 2×GMF spectra, and rotor imbalance spectra etc; the increased speed and load will significant strengthen the energy of the plastic planetary geared system in 1 × GMF spectra and restrain the effect of rotor imbalance; the increased load will control the energy in the 2×GMF spectra.
