按工作行程传动角最优设计偏置曲柄滑块机构

Design of Offset SliderCrank Mechanism with Optimum Transmission Angle over Working Stroke

提出一种工作和空回行程分别按不同的许用传动角设计偏置曲柄滑块机构的方法，它使Ｋ＞１急回运动机构的Ｋ值有较大的增加，扩大了这种机构的应用范围，提供的方法和线图使机构的设计简捷、方便和实用，文中还附有设计计算例。

A method in which allowable transmission angles of working and return stroke are different from each other used to design offset slidercrank mechanism is presented. The significant results are that the time ratio of quickreturn mechanism is increased and its feasible range is enlarged.The approach and chart render the design simple,easy and practicable.Illustrating examples are given in this paper.
