当前我国各个工业领域正在积极地应用微电脑技术,改造普通机床为经济型数控机床,因此很多人注意学习微电脑技术。但是,作为普通机床改为经济型数控机床,必须使用的新型机械元件滚珠丝杠,很多人不太了解。为了加快经济性数控机床的推广,充分发挥数控机床特性,现简要地介绍一下滚珠丝杠的技术知识。滚珠丝杠副传动元件就是在丝杠螺纹槽和螺母螺纹槽之间装入滚珠,滚珠作为中间传递物,使丝杠螺母的相对运动由滑动变为滚动,使其提高传动效率,并产生一系列的优异特性。 1.传动效率高:由于摩擦系数低,传动效率是普通丝杠的三倍到四倍,
At present, China’s various industrial fields are actively applying microcomputer technology to transform ordinary machine tools into economical CNC machine tools, so many people pay attention to learning microcomputer technology. However, as an ordinary machine tool to economic CNC machine tools, you must use the new mechanical components ball screw, many people do not understand. In order to speed up the promotion of economic CNC machine tools, give full play to the characteristics of CNC machine tools, is now briefly introduce the technical knowledge of ball screws. Ball screw vice transmission element is in the screw thread groove and nut thread groove into the ball, the ball as the intermediate transmission, the relative movement of the screw nut from sliding to rolling, so that it can improve the transmission efficiency and produce a Series of excellent features. 1. Transmission efficiency: Due to the low friction coefficient, transmission efficiency is three times to four times the normal screw,
