摘要
本文将确定由曲柄摇杆机构转化为曲柄直导杆机构的三个转化参数，并指出由耙取机构插入段开始时的转化角θ（Ｎｙ）所对应的曲柄导杆机构为最佳转化机构。
In this paper,three parameters have been fixed, which are changeover conditions between crank--rocker mechanism and crankguider mechanism. The author also puts forward that the crank-guider mechanism, based on the changeover angle 0(Ny) at the beginning point of interpolation stage, is optimal changerover mechanism.
