考虑润滑剂剪切强度,计算等温纯滚动弹流膜厚.回归出的中心膜厚公式表示不同工况下弹流润滑偏离经典理论的程度.这种偏离实际代表在严重发热的弹流润滑中,入口区润滑剂剪切强度或润滑剂/接触表面界面处最大可承受剪应力下降时,弹流润滑失效前润滑膜的厚度.
Considering the shear strength of the lubricant, the isothermal pure rolling elastic film thickness is calculated, and the regressed central film thickness formula shows the degree of deviation of the elastohydrodynamic lubrication from the classical theory under different working conditions. , The shear strength of the lubricant in the entry zone or the maximum thickness of the lubricated film before failure of the elastohydrodynamic lubrication at the maximum permissible shear stress at the lubricant / contact surface interface.
