《机械工人技术资料》1976年第8期刊登的《展成法铣链轮》一文,介绍了利用链轮在直线链条上作纯滚动的原理,在铣床上通过保证分度头与工作台走刀丝杆的严格速比来展成链轮的方法。这种方法不需要特殊的机床、复杂的刀具和夹具,就能比较容易地实现对各种齿数链轮的加工。 “Mechanical workers technical information” published in 1976 No. 8, “the development of milling sprocket,” a paper describes the use of sprockets in the linear chain for pure rolling principle, in the milling machine by ensuring the indexing head and the workbench to go Sword screw speed ratio to develop a sprocket method. This method does not require special machine tools, complex tools and fixtures, can be easily achieved on all kinds of gear sprocket processing.
