螺纹是机械制造中紧固连接传动的基本形式,随着科技的发展,对螺纹零件导程的要求更多更复杂,单靠车床铭牌上的螺距是已满足不了生产的需要,有关书籍和杂志上也不断介绍了较好的解决方法,基本上都是配置四个齿轮重新组合挂轮比,有时还得改进车床挂轮架。本文介绍的方法,只配置一个齿轮,不需改进挂轮架,就可以解决一大批多线螺杆,多头蜗杆及特殊螺旋零件的加工。 Thread is the basic form of fastening and connecting transmission in machinery manufacturing. With the development of science and technology, the requirements of the lead of the threaded parts are more and more complicated. The pitch on the nameplate of the lathe can not meet the production needs. Books and magazines On the continued introduction of a better solution, basically are configured to re-combination of four gear wheel ratio, and sometimes have to improve the lathe rack. This article describes the method, only one gear configuration, without the need to improve the rack, you can solve a large number of multi-line screw, long worm and special spiral parts processing.
