| Abstract: | On the basis of theoretical analysis of elastohydrodytiamic lubrication ( EHL ) and experimental study of traction mechanism in point contacts, the distributions of traction on contact surfaces and subsurface stress field have been studied in this paper. Furthermore the service life which is dominated by fatigue failure of traction drives has been analyzed. Effects of several kinds of parameters such as load, elliptical parameters etc on stress field have been analyzed. The influence of slip at or near the contact surfaces on traction drives has been studied. |
