摘要提出了一种精确测量直齿圆柱齿轮齿对刚度的方法。当齿角接触发生时，该方法揭示了整个正常接触路径的刚度行为，并进入扩展接触区域。该方法利用了齿载荷范围内平均和交变分量的传动误差图的特性(Harris图)。它避免了测量牙齿挠度时的常见问题，即其他试验台部件的挠度很难消除。还包括一对高重合度直齿圆柱齿轮的预测哈里斯图，显示了各种简化假设的影响，以及测量图。
Abstract A method is presented that allows the accurate measurement of the tooth pair stiffness of a pair of spur gears. The method reveals the stiffness behaviour throughout the full length of the normal path of contact and also into the extended contact region when tooth corner contact occurs. The method makes use of the properties of transmission error plots for mean and alternating components over a range of tooth loads (Harris maps). It avoids the usual problem when measuring tooth deflections that deflections of other test rig components are difficult to eliminate. Also included are predicted Harris maps for a pair of high contact ratio spur gears, showing the effects of various simplifying assumptions, together with a measured map.
