摘要

The global bifurcation characteristics about motion state about dimensionless frequency ??? and the mean meshing force Pm are studied based on the classical nonlinear dynamical model of a gear pair with clearance in this paper. The results reveals that Periodic motion is the gear pair??s main motion state in the range of 0.5 ??£ ??? ??£ 2.5 and it just appears chaos motion in a small range 0.62 ??£ ??? ??£ 0.92 temporarily; the way to chaos is periodic-doubling bifurcation with dimensionless frequency??? decreases; Periodicmotion is the system??smain motion state in the range of m 0.1 ??£ p ??£ 1.4 and it just appears non-periodic motion in a small Pm range of m 0.01 ??£ p ??£ 0.1 ; theway to chaos is periodic-doubling bifurcation with the mean meshing force Pm decreases.
