基于正交试验的回转唇形油封结构参数优选
Structural Parameter Optimization of Rotary Lip Oil Seal Based on Orthogonal Experiments
摘要
Abstract
Oil seals are critical sealing components in mechanical equipment,and the influence of their structural parameters on sealing performance has long been a key focus in the industry.The maximum contact pressure at the main lip of a rotary lip oil seal is taken as the experimental indicator to conduct an in-depth analysis of the influence of structural parameters on sealing performance.A method based on ANSYS finite element software is presented to obtain the contact pressure distribution at the main lip,laying the foundation for subsequent analysis of the influence of structural parameters on sealing performance.Through systematic simulation experiments,the influence of maximum contact width,interference fit,front lip angle,rear lip angle,and waist width on the maximum contact pressure at the main lip is analyzed.For a rotary lip oil seal design on the output shaft of a reducer,an orthogonal experimental plan is developed,and the maximum contact pressure for each scheme is obtained through finite element simulation.Utilizing range analysis,the influence degree of the aforementioned structural parameters on the maximum contact pressure is analyzed,and an optimal parameter scheme is determined.To validate the superiority of this parameter scheme,a simulation model is established and compared with the various schemes from the orthogonal experiment.The simulation demonstrates that,compared to the orthogonal experimental schemes,the optimized scheme can improve the maximum contact pressure of the rotary lip oil seal by more than 20.48%,significantly enhancing the sealing performance.关键词
