The load sharing analysis of planetary transmissions has significant influence on the operation and reliability of the gear system. In order to reveal the impact of crack propagation on the load sharing behaviors, a nonlinear lumped-parameter model of the compound planetary gear set with cracked sun gear is established. The mesh deformation of each mesh pair without and with crack are numerically analyzed. The time histories, FFT spectra, phase portraits and Poincaré maps are adopted to investigate the influence of crack propagation on the nonlinear dynamic behaviors of the system. Further, the load sharing ratio (LSR) with respect to different crack levels are calculated and the influence of crack propagation on the load sharing characteristics of the system is discussed. The results will be useful for fault diagnosis and reliability analysis of the planetary gear transmissions. |
