Abstract
Abstract The effects of the textured shaft on the wear and sealing performance of rotary lip seals have recently attracted considerable attention. This paper presents a numerical method for analyzing the effects of the textured shaft on the seal performance, especially the seal wear. The proposed numerical analysis method has been validated by comparing the simulation results to experimental observations. Based on the simulation results, this study finds that: increasing the textured feature depth and increasing the textured area ratio can increase the seal life and improve the torque of the seal, especially in the axial direction. The reverse pumping rate decreases with the increase of textured area ratio, especially in the axial direction.
