Abstract

A theoretical model is developed to analyze the axial and circumferential movements of rotary seal ring. The model considered several key coupled physical processes such as two-dimensional motion, fluid lubrication with spiral grooves, and asperity contact. The transient nonlinear dynamic problem is solved by efficient multistep method. To verify the cause of creep rotation of seal ring, the model is applied to analyze the axial and creeping motion with and without shaft oscillating movements. Additionally, effects of spiral grooves on creep rotation are also discussed.
