【摘要】 讨论了平面连杆机构急回系数、极位夹角与原动曲柄转角之间的关系,采用分段函数给出急回系数与极位夹角的通用关系式,解决了目前机械原理教科书中所确定的急回系数与极位夹角的关系不适用于急回系数大于3的连杆机构的问题,从而为正确分析及设计平面连杆机构提供基础。文中给出两个实例。更多还原

【Abstract】 The general relationship between advance-to return-time ratio(K)and crank angle between extreme positions(θ)of planar linkage is discussed.The results which are given in the form of segmented functions can solve the problem existed in the present texts.The problem is that the relationship between K and θ of planar linkage is not adaptable for the case when K is greater than 3.The general functions presented in this paper is important for the design and analysis of planar linkage.Two examples are given.更多还原
