摘 要
摘要：曲柄连杆是若干构件用低副连接成的机构。曲柄连杆机构中的构件大都可以表示为杆状，故亦称其为杆.由于低副是圆柱面或平面接触,使得平面连杆机构具有制造容易、运动副中压强和磨损较小、便于润滑等优点，因此平面连杆机构广泛用于天各种机械及仪器中。但是，这种机构运动副磨损后会形成间隙，当构件数目较多时，会使从动件产生较大的运动累积误差，不容易精确地实现复杂的运动规律。关键词： 曲柄 连杆。
Abstract
Crank connecting bar is a mechanism that severial mechanical components are connected by low counter gear. The mechanical components of crank connecting bar can normally be expressed as rodlike forms, so we can also called it “bar”. Due to low counter gear indicats a cylindrical surface contact or a plane surface contact，planar linkage mechanisms has a numbers of advantages such as easy manufacture, relatively small pressure and abrasion of kinematic pair, and easier lubrication, so which has been widely used in various machinery and apparatus. However, a gap will be formed after this kind of mechanism of kinermatic pair is fretted away. Followers will lead to accumulated error of movement when there is a relative large number of mechanical components, so which is not easy to precisely realize the complicated law of motion.Key words: crank connecting bar
