近年来随着齿轮制造工艺水平的提高,滚齿加工质量有所提高,这样以剃齿作为糟加工的齿轮,适当减少剃齿余量,不但可满足产品严求,而且还可提高生产效率。本文介绍合理确定剃齿余量的计算。剃齿余量可沿齿轮啮合线方向计算,由于渐开线圆柱齿轮的啮合线是渐开线齿轮传递力和运动的作用线,啮合线方向总作用误误差(即啮合线增量)直接影响齿轮的使用性能。因此,减少啮合线方向误差有利于提高剃齿等的齿轮精加工精度。齿轮啮合线增量减少了,也就减小了齿轮各项误差。齿轮的各项误差虽在不同方向上度量,但通过各检验组检测齿轮,其实质都反映了齿轮啮合线增量。齿轮的总误差也是通过直
In recent years, with the improvement of gear manufacturing technology, the quality of hobbing has been improved. In this way, gear shaving can be used as a bad gear to reduce shaving allowance, which can not only meet the strict requirements of products but also increase the production efficiency. This article describes the reasonable determination of shaving teeth margin calculation. The shaving allowance can be calculated along the direction of the gear meshing line. Since the meshing line of the involute spur gear is the line of force transmission and movement of the involute gear, the total error in the direction of the meshing line (ie, the incremental of the meshing line) is directly affected Gear performance. Therefore, reducing the error in the direction of the engaging line is advantageous for improving the gear finishing accuracy of shaving gears and the like. Increased gear meshing line is reduced, it reduces the gear error. Although the error of the gear in different directions measured, but through the test group testing gear, its essence reflects the gear meshing line incremental. The total error of the gear is also straight
