齿轮传动在理论上是传递运动和动力的正序啮合过程。当温度变化、安装误差、制造误差或变形发生时，法阶啮合将被破坏。在一定条件下，接触点在齿面上以与法向相反的方向移动。这个过程称为齿轮逆序啮合。齿轮的逆序啮合会导致齿轮在传动过程中产生冲击和噪声。本文以基节偏差齿轮副为研究对象，对该过程进行了进一步的研究，并将其应用范围扩展到运动学和动力学领域。推导了齿轮逆序啮合过程的传动误差。得到了速度误差和加速度误差。基于这三个变量的曲线，分析了齿轮逆序啮合对齿轮传动特性的影响，探讨了啮合冲击现象产生的原因。齿轮逆序啮合过程虽然存在一些缺点，但也有一定的应用前景。根据齿轮逆序啮合的特点，将其有效地应用于齿轮综合误差（GIE）测量技术和跳齿珩齿加工中。
The gear drive is theoretically a normal-order meshing process to transmit movement and power. When temperature variation, misalignment, manufacture error, or deformation occurs, the normal-order meshing will be destroyed. Under certain conditions, the contact point moves in the opposite direction to the normal order on the surface of the tooth. This process is called gear reverse-order meshing. The gear reverse-order meshing will lead to gear impact and generate noise during the transmission. In the study, with gear pairs with base pitch deviation as the study object, we further studied this process and expanded the application scope of the process to kinematics and dynamics. The transmission error of the gear reverse-order meshing process was deduced. Both the speed error and acceleration error were obtained. Based on the curves of these three variables, the influence of gear reverse-order meshing on gear transmission characteristic was analyzed to explore the causes for the meshing impact phenomenon. Although the gear reverse-order meshing process has some disadvantages, it could also be applied in some fields. Due to the feature of gear reverse-order meshing, it is applied to gear integrated error (GIE) measuring technique and tooth-skipped gear honing process effectively.
