摘要

在曲柄摇杆机构设计中

极位夹角θ

摇杆摆角的确定

直接影响到机构达到一定传力性能的可能性

这一可能性即可由铰链中心A取点范围Δt来表示。我们利用计算机分析了θ、和铰链中心A取点范围Δt之间的关系

从而将θ、的确定与传力性能相联系。当一定时

随着θ值增大

满足rmin≥ [r]的A点取值范围Δt越少

当θ >θ极大时

Δt值减少为零

机构不能满足传力性能的要求。此外

还得出不同值时所对应的θ极大值

并以θmax—曲线表示了与θ极大之间关系

为实际设计中

机构急回程度及摆角的确定提供了依据。

Abstract

In the course of designing crank and rocker mechanism

the value of polar-place included angle

rocker swing angle will have an influence on the performance of force-transfering. The passibility depends on the scope within which hinge center A is setted

Computer sofetwares was applied to analyse the relation between polar-place included angle

rocker swing angle and scope of center settling. If the rocker swing angle remains unchage with in increasing of value θ

the scope hinge center will reduce. When θ>θ max

the Δt will cut down to zero

and the mechanism can not meet demands of force-transfering. If Φ changes

θ max will change. The researches provided a theoretical foundation for the design of crank and rocker mechanism.
