基于弹性流体动压润滑理论选择齿轮油粘度的可靠性计算

摘要

The paper determines the viscosity of gesr lubrication oil by uing reliability method.According to relations betqeenminimal oil-filmthickmessand tooth-face roughness in elastohydrodynamic lubrication theory,calculation fomula is presented and acual calulation os cattied out.%根据弹性流体动压润滑理论的最小油膜厚度与齿面粗糙度的关系用可靠性方法确定齿轮润滑油的粘度，给出计算公式并进行了实例计算。此法克服了经验选油法的局限性，将齿轮润滑油粘度的选择提到理论高度并可直接算出具体数值。
