Abstract This paper presents a study on the influence on the quasi-static transmission error of symmetric long profile modifications on high contact ratio spur gears. A previously developed model for the load sharing ratio and quasi-static transmission error, based on the hypothesis of equal delay interval in all the teeth in simultaneous contact, has been used. The simple formulation of the model allows to obtain the equation of the required profile modification to ensure a preestablished function of load sharing ratio or quasi-static transmission error. From this model, the tip reliefs for minimum peak-to-peak amplitude of quasi-static transmission error and for minimum dynamic load, have been obtained. In both cases, the optimum length of modification has been expressed as a function of the contact ratio.

对称齿廓修正的高接触比正齿轮传动误差控制

摘要 本文研究了对称长齿廓修形对高接触比正齿轮准静态传动误差的影响。已经使用了先前开发的负载分配比和准静态传输误差模型，该模型基于同时接触的所有齿的延迟间隔相等的假设。模型的简单公式化允许获得所需剖面修正的方程，以确保预先建立的负载分配比或准静态传输误差函数。从这个模型中，已经获得了准静态传输误差的最小峰峰值幅度和最小动态载荷的尖端起伏。在这两种情况下，改性的最佳长度都表示为接触比的函数。
