在汽车的变速箱内,有一些直齿或斜齿圆柱齿轮和花键轴是连成一体的。加工这一类齿轮,在缺少专用机床或专用刀具条件下:确是比较困难的。以前,我们曾经利用靠模装置,把它装在万能铣床上加工,然而,加工质量往往达不到图纸的要求。以后,通过学习和研究兄弟厂齿轮机床结构,终于改装成一台用梳齿刀工作的简易立式刨齿机。 In the car’s gearbox, there are some spur or helical spur gears and spline shafts that are integral. Processing this type of gear, in the absence of special machine tools or special tools: it is more difficult. Previously, we used to rely on the device to install it on a universal milling machine processing, however, the quality of the processing often do not meet the requirements of the drawings. Later, by studying and researching the structure of the brother factory gear machine, it was finally converted into a simple vertical planing machine working with a comb-tooth cutter.
