To evaluate thermal characteristics of lubricating film under spinning-sliding condition,a thermal elasto-hydrodynamic lubrication(EHL)elliptical contact model based on Carreau rheological model was established,and numeri-cal solutions were obtained for a spinning-sliding EHL.A comparison of thermal EHL characteristics between isothermal and thermal conditions was earried out.Effects of the angular velocity,the load,the ellipticity and the spinning factor on the spinning-sliding EHL were analyzed.Results show that,thermal effects cannot be neglected under spinning-sliding condi-tion,which leads to thinner oil film.The increase in the angular velocity,the load,the ellipticity and the spinning factor en-hances the spinning effect,which leads to the increase in asymmetry of oil film distribution.With the increase of angular ve-locity,the temperature of stationary solid and oil film increases,whereas the temperature of moving solid changes a little,increasing firstly and then decreasing.With the increase in the maximum Hertzian pressure,the temperature of solid and oil film increases linearly.The spinning factor has little effect on the film pressure,the film thickness and the temperature,however,it results in the asymmetric distribution of the film thickness and the temperature.The performance of the spinning-sliding EHL is affected by the ellipticity in a specific range.
