现以制作套筒滚子链链轮为例,介绍只利用车床、钳工工具等进行加工的方法。 1.首先根据被加工的链轮节距及齿数,查表算出分度圆、齿顶圆及齿根圆直径。考虑到加工的方便,在选用齿顶圆直径时,为防止顶切及加工误差,建议选用最小外径,这样做对强度影响不大又能满足使用要求。 Now making sleeve roller chain sprocket, for example, describes the use of lathe, fitter tools, etc. for processing methods. 1. First, according to the processed sprocket pitch and number of teeth, check the table to calculate the index circle, addendum circle and root circle diameter. Taking into account the processing convenience, the use of addendum circle diameter, in order to prevent the top cut and machining errors, it is recommended to use the smallest diameter, which has little effect on the strength and can meet the requirements.
