design model of linkage stepping mechanism 3D 模型

linkage mechanism is also called low pair mechanism. it is a kind of mechanism composed of several (more than two) components with certain relative motion, which are connected by low pairs (rotating pairs or moving pairs). the most basic and widely used type of planar linkage mechanism is the planar four-bar mechanism composed of four components. since most of the components in the mechanism are rod-shaped, they are often called rod-shaped components. [1] in addition, the contact surfaces of the rotating pair and the moving pair are cylindrical and plane, so the manufacturing is simple and easy to obtain high manufacturing accuracy. connecting rod mechanism is widely used in various machines and instruments. 打印准备: 否
