等效粘度修正超薄膜润滑的温度场分析

摘要

Lubricating performance of oil liquid is affected as its viscosity varies with the temperature. Because the bearing clearance is very small under thin film lubrication, the flux of lubricant is small in the clearance, and quantity of heat gone out is decreased. Therefore, the adsorbent property is influenced. The temperature may be higher. The effect of the lubricant performance will be greater. The infection of lubrication effect will exceed routine lubrication state. The energy equation is applied to analyze temperature field. The lubrication and load capacity are derived under thin film lubrication.%润滑剂的粘温特性影响其自身的润滑性能，在薄膜润滑中由于间隙极其微小，间隙内润滑剂流量少，带走的热量减少，影响吸附性能，从而可能形成更高的温升，对润滑剂的性能影响也将更大，对润滑效果的影响将超过常规的润滑状态。本文运用能量方程进行超薄膜润滑条件下的温度场分析，以便求解在薄膜润滑条件下轴承的润滑及承载性能。
