In order to effectively assess the thermal characteristics of lubrication film,using the Eyring nonNewtonian fluid,the thermal elastohydrodynamic lubrication model considering spinning was built,and numerical simulation was carried out with multigrid method and column by column sweeping technique.The effects of the slidroll ratio and speed,the characteristics of shearing stress,the maximum Hertzian pressure and the spinning factor on the elastohydrodynamic lubrication performances were discussed.Results show that,the main difference between nonNewtonian and Newtonian fluid is that the oil film temperature for the nonNewtonian fluid is significantly lower than that of Newtonian fluid for the moderate or high load considering spinning.The symmetry of distribution of the film thickness and temperature disappears because of spinning.For the nonNewtonian fluid with lower characteristic shearing stress,the irregularity of the temperature distribution is more obvious due to the spinning.With the increase of load,the friction coefficient is firstly increased linearly,while the thermal effect is also gradually strengthened with the load increasing,so the friction coefficient has a decreasing trend after reaching the maximum value.With the increase of spinning factor,the asymmetry of film thickness and temperature distribution are increased,the highest temperature goes up and moves towards one side.
