摘　　要：为了研究大模数齿轮齿条传动副在齿面剥落故障情况下的啮合刚度,以三峡升船机齿轮齿条传动系统作为研究对象,在沿齿宽方向上设置了3种不同长度的剥落尺寸来模拟不同程度的剥落故障,采用能量法分析了正常工况下和剥落故障工况下齿轮参数变化对啮合刚度的影响;同时,采用有限元方法对啮合刚度进行分析,并将其结果与解析法进行对比,验证了解析法的正确性,实现了剥落故障条件下齿轮齿条副啮合刚度的快速计算,对大模数齿轮齿条传动的动力学分析具有重要意义。In order to study the meshing stiffness of a large module gear rack transmission pair under the condition of tooth surface spalling failure,in this paper,the rack and pinion transmission system of Three Gorges ship lift is taken as the research object.Three kinds of spalling sizes with different lengths are set along the tooth width direction to simulate different degrees of spalling faults.The influence of gear parameters on mesh stiffness under normal working conditions and spalling fault conditions is analyzed by energy method.At the same time,the finite element method is used to analyze the meshing stiffness,and the results are compared with the analytical method,which verifies the correctness of the analytical method,and realizes the rapid calculation of the meshing stiffness of the rack and pinion pair under the condition of spalling fault,which has important significance for the dynamic analysis of the large modulus rack and pinion drive.
