摘要

针对某款纵置变速器在市场上反馈结合面有渗油,首先,用有限元方法分析壳体结合面的静态间隙,再考虑变速箱的一挡和倒挡工况,分析壳体结合面的动态间隙;然后,针对该壳体做了面压试验,验证了理论分析的正确性,同时找到漏油是由于壳体结合面质量造成;最后,模拟变速器的实际装箱条件,涂上密封胶后再做面压试验,结果显示结合面的压力均匀,结合面密封可靠,证明理论设计无问题,为变速器壳体结合面密封性研究提供参考。

Abstract

Against the phenomenon that oil leakage at joint of one longitudinal transmission is fed back from market,firstly,the finite element method is applied to analyze the static gap of joint surface of housing.Secondly,considering the working conditions of first gear and reverse gear,the dynamic gap of the joint surface of housing is analyzed,and a surface pressure test against the housing is carried out,the correctness of theoretical analysis is verified,meanwhile it is found that the oil leakage is caused by the quality of the joint surface of the housing. At last,simulating the reality of transmission producing,the joint surface is coated with sealant before making a surface pressure test which shows that the joint surface has uniform pressure and reliable seal,and the theory design is proved to be free of problems,a reference for the study of the tightness of transmission housing joint surface is provided.
