摘要

计及时变啮合刚度、传递误差及摩擦力等对人字齿轮副动力学特性的影响，建立了人字齿轮副平移-扭转振动分析模型。在获得动载荷的基础上，结合混合弹流润滑理论计算了混合弹流润滑摩擦因数。基于Block闪温理论研究了齿轮啮合过程中的齿面温升效应，获得了齿面温升沿啮合线的分布规律。分析了齿面温升、齿面粗糙度和载荷对齿面摩擦因数的影响规律。研究了人字齿轮在耦合和非耦合状态下的振动特性。结果表明，齿面摩擦对齿轮系统的动态响应有影响，由摩擦导致的齿面温升对摩擦因数影响较大。

Abstract：A translation-torsional dynamics model for herringbone gear pairs was proposed, in which the time-varying mesh stiffness，transmission error，as well as the friction force were considered.On the basis of acquiring dynamic load, according to the mixed elastohydrodynamic lubrication theory, a corresponding friction coefficient was calculated.By virtue of the Block flash temperature theory，the distribution of tooth surface temperature rise along the meshing line was obtained, the effect of tooth surface temperature rise during gear meshing was also investigated.The influences of tooth surface temperature rise, tooth surface roughness and load on the friction coefficient were analyzed.Subsequently, the vibration characteristics of herringbone gears in coupled and uncoupled states were studied.The results show that tooth surface friction has an impact on the dynamic response of the gear system.Moreover，the temperature rise effect of the tooth surface caused by friction has a greater impact on the friction coefficient.

Key words： herringbone gear mixed elastohydrodynamic lubrication tooth surface friction；dynamic response friction coefficient
