摘要

为了研究齿轮副在实际工况下的啮合效率，对齿轮副接触面进行受力和运动学分析，结合弹流润滑理论对齿轮副的润滑状态进行判断，建立了在弹流润滑和混合润滑状态下的动态摩擦因数数学模型，得到齿轮副沿啮合线不同啮合位置的摩擦因数；从受力的角度出发，推导出齿轮副啮合效率计算式，引入动态滑动摩擦因数，得到符合实际工况的齿轮副啮合效率；结合Matlab仿真分析软件，分析了传动比和小齿轮齿数对滑动摩擦因数及齿轮副啮合效率的影响。结果表明，基于动态滑动摩擦因数的齿轮副啮合效率计算方法与实际工况具有良好的一致性，对齿轮传动设计具有一定的指导意义。

Abstract

In order to study the meshing efficiency of the gear pair under the actual working conditions

the force and kinematics of the contact surface of the gear pair are analyzed

the lubrication state of the gear pair is judged by combining the theory of elastohydrodynamic lubrication

and the relationship between the elastohydrodynamic lubrication and the mixed lubrication state is established. The mathematical model of the dynamic friction factor is used to obtain the friction factor of the gear pair at different meshing positions along the meshing line. From the point of view of force

the calculation formula of gear pair meshing efficiency is deduced

and the dynamic sliding friction factor is introduced to obtain the result of gear pair meshing efficiency that conforms to the actual working conditions. Combined with the simulation analysis software

the influence of the transmission ratio and the number of pinion teeth on the sliding friction factor and the meshing efficiency of the gear pair is analyzed. The results show that the calculation method of the gear pair meshing efficiency based on dynamic sliding friction factor is in good agreement with the actual working conditions

which has certain guiding significance for gear transmission design.
