... of tooth surface wear depth and wear life of DIG under dry contact and mixed EHL. The comparison shows that the distribution of surface wear depth of pinion and gear under the mixed EHL is similar to that under the dry contact, but the tooth surface wear depth under the mixed EHL is nearly four orders...

..., and elliptical contacts of various ellipticity ratios. The speed range for analyzed cases covers 11 orders of magnitude so that the entire transition from full-film and mixed EHL down to dry contact (corresponding λ ratio from about 3.5 down to 0.001 or so) is simulated. Three types of machined surfaces are used...

... and challenging field of research since the 1950s. Significant breakthroughs achieved in the last 10–15 years are largely in the area of mixed EHL, in which surface asperity contact and hydrodynamic lubricant film coexist. Mixed EHL is of the utmost importance not only because most power-transmitting components...
