Abstract

The flash temperature of the cam-roller contacting surface for a marine diesel engine was analysed numerically. The elastohydrodynamic lubrication pressure and film thickness were adopted to get more accurate frictional coefficient, heat flux and temperature distribution. The maximum flash temperature was increased with both the increasing slip ratio of the contacting surfaces and increasing external load. This study tells that the temperature analysis is an indispensable procedure in designing elastohydrodynamic lubrication contacts on which the slip occurs.
