我厂在普通车床上附加一套齿轮、曲柄连杆组合机构加工近似椭圆,加工质量完全符合产品要求,经济效果较好。一、近似椭圆加工原理近似椭圆的加工原理如图1所示。图l是车床附加机构的示意图。附加机构由曲柄滑块和齿轮组成。大齿轮与所要加工的椭圆连接,小齿轮与曲柄连接。通过中间齿轮的搭配,使椭圆和曲柄的博速比为1:2,
I plant in an ordinary lathe attached to a set of gears, crank connecting rod assembly approximate ellipse processing, processing quality in full compliance with product requirements, the economic effect is better. First, the approximate elliptical processing principle Approximate elliptical processing principle shown in Figure 1. Figure l is a schematic view of the lathe additional mechanism. Additional mechanism consists of crank slider and gear. The big gear is connected with the ellipse to be machined, and the pinion is connected with the crank. Through the middle gear with the oval and crank the speed ratio of 1: 2,
