项目摘要

This research aims at development of high precision measurement and estimation methods of gear transmissions.1. Using two rotary encoders that have angular resolutions of 0.072 arc-sec., generated pulses from those encoders (each channel has 32-bits data length) can be detected speedily and simultaneously. The measuring instrument with those encoders is attached to the back-to-back type gear testing machine. It is clarified that the newly developed single flank gear testing system has enough accuracy for estimation of gear transmission errors under load.2. Ground helical gears having various tooth flank configuration errors are tested with and without an alignment error under several quasi-static loading conditions. Under no load, a suitable amount of crowning can avoid sudden changes of transmission errors. On the other hand, under load, optimum tooth profile modification seems to exist. When crowning is made, the more loads increase, the larger the transmission error variations become. That probably depends on the relation between the starting position of modification and the amount of it.3. The influences of changes of contact points and the load sharing on the transmission characteristics are investigated. In the calculated results, contact points move from line of action according to tooth profile modifications and loads. The heavier the applied loads become, periods of double tooth contact become wider and those of single tooth contact become narrower. Amplitude of transmission errors can be reduced to a minimum at the load that the real contact ratio agrees with the theoretical contact ratio. When the real contact ratio is larger than the theoretical contact ratio, periods of tooth-tip-edge contact will occur.

本研究旨在发展齿轮传动的高精度测量与评估方法.使用两个角分辨率为0.072弧秒的旋转编码器，从这些编码器（每个通道具有32位数据长度）产生的脉冲可以被快速且同时地检测。将带有这些编码器的测量仪器安装在背靠背式齿轮试验机上。研究表明，新开发的单面啮合齿轮检测系统具有足够的精度，能够准确地估计齿轮在载荷作用下的传动误差.在几种准静态载荷条件下，对具有不同齿面形状误差的磨斜齿轮进行了有无对中误差的试验。空载时，适当的凸度可避免传动误差的突变。另一方面，在负载下，最佳齿廓修改似乎存在。当进行凸面时，负载增加得越多，传动误差变化就变得越大。这可能取决于修饰的起始位置和修饰量之间的关系。研究了接触点位置变化和负载分配对传动特性的影响。在计算结果中，接触点根据齿廓修改和载荷从作用线移动。载荷越大，双齿接触周期越宽，单齿接触周期越窄。在真实的重合度与理论重合度一致的载荷下，传动误差的幅值可以减小到最小。当真实的重合度大于理论重合度时，会出现齿尖接触周期。
