Ⅲ-Ⅳ级六杆机构的传力特性分析及曲柄存在准则

Analyses to the Characteristics of Force-Transfer and the Existence Criteria of Grades Ⅲ - Ⅳ Six-Bar Linkages

本文讨论了Ⅲ级六杆机构的曲柄存在准则及其使用方法;研究了几种六杆机构的传力特性;得出几条重要结论;提出用“合力臂”评价六杆机构传力特性的方法;并对常用六杆机构的实用性作出了定性的评价。

This paper disc es the existence criteria of the crank of grade Ⅲsix-bar linkage artc ins operation method .studies force-transfer characteristics of a few six-bar linkages,obtains several pieces of important conclusions . aises the method that 'the arm of resultant forces' can be used to evaluate the force-transfer characte istic of yade Ⅳsix-bar linkage,and makes qualitative evaluation to the practicability of common six bar linkages.
