摘　　要：以齿轮传动不发生胶合、磨损等齿面失效为前提,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。克服了传统的经验法选择齿轮润滑油粘度的局限性,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。Taking gear without tooth face invalidation such as agglutination and abrasion as a precondition,and according to the relation between maximal oil film thickness and tooth face roughness of elastic liquid dynamical pressure lubricate theory,viscosity of gear lubricities oil was educed by reliable method in this paper,and calculated formula has been elicited and applied.This method overcomes the disadvantage of traditional one that choosing viscosity of gear lubricities oil according to experience and can working-out concrete numerical value directly and enhance choosing viscosity of gear lubricities oil to a theory height.
