Abstract：Gear skiving process has the advantages of high material removal rate,good forming accuracy and so on,and can realize the efficient machining of gears with special structure such as inner gears.It can effec-tively improve productivity and reduce cost by advancing the finishing process of gears.However,due to the presence of feed marks on the forming tooth surface,the contact performance of the tooth surface is not clear.In this study,firstly,according to the kinematic principle of gear skiving,a solid model of gears with non-smooth tooth surface is constructed.Then,the contact stress of non-smooth tooth surface is simulated by the finite ele-ment method,and the results are compared with the calculation results of the bearing capacity of gears recom-mended by international standards.Finally,the influences of feed and tooth modification coefficient on gear con-tact stress are analyzed.The results show that there is a nonlinear positive correlation between the contact stress and the feed.The tooth modification has little effect on the extreme value of contact stress,but has significant ef-fect on the stress distribution area.
