摘　　要：对平面低副四杆机构极位夹角的定义进行了探究,提出了一种可以解决实际问题的全新概念,扩展了平面低副四杆机构极位夹角的取值范围,更符合工程实际,具有较强的实用性,为设计出急回程度更大的机械提供了依据。Probation was carried out on the definition of the extreme positional included angle of planar low paired four bar linkages, and a kind of brand new concept that may solve the practical problem has been put forward. The valuing ranges of extreme positional included angle of planar low paired four bar linkage were extended, which corresponds more with the engineering practice and possesses rather strong practicality, thus provided basis for scheming out the machinery with larger quick return level.

关 键 词：急回运动特性 极位夹角 行程速比系数
