Research on Relationship between Modulus and Tooth Number of Transmitting Gear and Vibration Noise

摘要

The dynamic model of gear driving system is built using centralized mass method in this paper. On the base of frequency domain and time domain results of model derived from equation of Fourier series, the example of a certain gearbox is calculated. Through adjusting the parameters of modulus and tooth number of gearbox, the dynamics computation is completed. The relationship between diversification of modulus and tooth number of gear and vibration noise is gained by comparatively analyzing the calculation results.
