摘　　要：偏置双曲柄滑块机构不仅具有k>3的超急回运动特性,而且具有可变急回运动特性,机构中各构件尺寸一定时,仅仅改变其相对安装位置,便可获得不同的行程速比系数。本文分析偏置双曲柄滑块机构的急回运动特性,给出了按最小传动角设计偏置双曲柄滑块机构的设计方法和设计曲线。The mechanism offset double crank slider not only has the characteristic of super quick-return (k>3),but also has variety time ratio. The time ratio of this mechanism is changed only the setting position is changed, when the sizes of all linker are determined. The characteristic of quick-return of offset double crank slider mechanism was analyzed in this paper. The synthesis method and curve of this mechanism with minimum transmission angle were presented.
