A twodimensional axisymmetric finite element model based on Ansys was presented to investigate the static contact properties of oil seal,the sealing lip stress and displacement were obtained,the effects of the various interference fits between the shaft and oil seal，rubberlike materials elastic modules and oil seal inner diameter on contact pressure,contact width and radial force were investigated.The results show that asymmetric distribution of contact pressure is more obvious when the interference fits is higher,the maximum contact pressure begins to increase then slowly decrease,the contact width increases slowly then grows rapidly,and the radial force linearly is increase with the interference fits;the amplitude of contact parameters is increased with rubberlike material modulus of elasticity,while decreased with oil seal inner diameter under the same interference fits.
