在没有专用设备的情况下,以前我们采用按齿数等分,在轮坯的大端和小端分别划出齿形,作出大端和小端的样板,然后磨出样板刀,在牛头刨床上刨出每个牙齿的方法加工直齿锥齿轮。这样不仅效率低,并且质量也差。在1964年11月,我们通过技术革新,技术革命,通过三结合,根据我厂的条件,利用了万能分度头和圆盘(回转工作台)及其他机床的交换齿轮,
In the absence of special equipment, in the past, we use the number of teeth divided equally between the large end and the small end of the wheel tooth profile were made to make big and small end of the model, and then grinding out the prototype knife shaver planing Out of each tooth straight bevel gear processing method. This is not only inefficient, but also poor in quality. In November 1964, through the combination of technology innovation and technological revolution, we used the universal indexing head and disc (rotary table) and the exchange gears of other machine tools according to the conditions of our factory.
