摘要

利用考虑热效应的Reynolds方程,对水润滑条件下的飞龙轴承进行考虑热效应时的弹流润滑理论分析。通过数值模拟讨论载荷、转速和轴径对水润滑膜压力及膜厚的影响。结果表明:热效应对水润滑膜压力的影响几乎可以不计,而膜厚减小;随载荷增大,压力峰值有所增大,膜厚随载荷的增大而减小;随转速的增大压力峰值减小,而膜厚随转速的增大而增大;轴径的大小对压力的影响不明显,但随轴径的增大膜厚减小。

Abstract

The elastohydrodynamic lubrication numerical analysis of water-lubricated Tenmat bearing is carried out by using the Reynolds equation with thermal effect.The effects of load,speed and shaft diameter on the pressure and film thickness of Tenmat bearing water lubrication film are discussed by the numerical simulation.The results show that thermal effect has little effect on the pressure,but the film thickness decrease under the thermal condition.The pressure peak is increased greatly with the increase of load,but the film thickness is decreased.The pressure peak is decreased with the increase of speed,but the film thickness is increased.The influence of shaft diameter on the pressure is not obvious,but the film thickness is decreased with the increase of shaft diameter.
