Abstract：[Objective]Aimed at the frictional heat generation problem of cylindrical roller thrust bearings caused by severe rolling-sliding between rollers and raceways under low-speed and heavy-load conditions,a study on the fluid-solid coupling temperature rise characteristics of bearings based on rolling-sliding characteristics was conducted.[Methods]A rigid-flexible coupled dynamic model of cylindrical roller thrust bearing was established via Adams software to analyze the rolling-sliding characteristics and cage slippage rate under different working conditions.A local method was adopted to construct a frictional power loss model,and the power loss was calculated by combining the post-processing parameters of Adams software.Based on the heat transfer theory,a fluid-solid coupling temperature rise model was established to study the temperature rise law of the raceway,and this model was verified through tests.[Results]The results show that the increase in axial load makes the pure rolling point approach the theoretical position and reduces the slippage rate.The increase in rotational speed causes the pure rolling point to first approach and then deviate from the theoretical position,and the slippage rate to first decrease and then increase.Under low-speed and heavy-load conditions,the growth amplitude of frictional torque decreases with the increase in axial load,and the frictional torque decreases with the reduction in rotational speed.The maximum error between the temperature rise simulation and the test is 8.98%.
