摘要
本文对转置双曲柄滑块机构急回运动特性进行了分析,结果讧明,此机构不仅具有超急回运动特性的可能性;而且在机构各构件尺寸一定的情况下,仅改变其相对安装位置,便可具有行程速比系数不同的急回运动特性。
In this paper, the quick-return action of the turnset slider-doublccrank mechanism are analysed, The result indicate that this mechanism not only have the possible of super-quick-return action but also get the varied travel speed ratio coefficient, changing the relative fix site on the condition the length of links are fixed.
