在万能铣床的分度头上,通过挂轮的方法利用圆柱形立铣刀可以铣切渐开线凸轮。现在把这种方法介绍如下,供同志们参考。大家知道,在半径为R_0的圆上(见图1),无滑动地滚动一条直线MM,直线上任何一点B的轨迹AB,便是渐开线。半径为R_0的圆称为基圆,直线MM称为发生线,C点称为发生线相对于基圆滚动时的瞬时中心,而线段(?)B称为渐开线B点的曲率半径。由于发生线MM是在基圆上做无滑动的滚动,因此渐开线
In the universal milling machine indexing head, the method of using the peg wheel cylindrical milling cutter can be milling involute cam. Now introduce this method as follows, for comrades reference. As we all know, on a circle of radius R_0 (see Fig. 1), a straight line MM is scrolled without sliding, and the trajectory AB of any point B on the straight line is involute. The circle of radius R_0 is called the base circle, the line MM is called the occurrence line, the point C is the instantaneous center of the occurrence line when it is rolling relative to the base circle, and the line segment (?) B is called the curvature radius of the point B of involute. Because of the occurrence of line MM is done in the base circle without sliding scroll, so involute
