用辅助圆图解法设计曲柄滑块机构

Crank-block Mechanism is Designed by Graphic Method of Auxiliary Circl

在给定行程速比系数K ,滑块行程h的情况下 ,另外再给定曲柄长度l1 或连杆长度l2 或许用压力角 [α]。

It should be that how to design the crank block mechanism with jerky reversal characteristic by graphic method of auxiliary circl in the case of given stroke and speed factors k and block travel h, and given lengths of crank l 1 or crank arm l 2 ,or needed pressure angles once more.
