尺寸链在机械制造中的应用洛阳工学院（４７１０３９）雷贤卿李航杨丙乾由一系列有关联的尺寸按一定顺序组成的封闭链图，称为尺寸链。在尺寸链中，间接保证的尺寸为该尺寸链的封闭环；其它的尺寸为该尺寸链的组成环，根据组成环对封闭影响不同可分为增环和减环。如用极值... Dimensional chain in the manufacture of machinery Luoyang Institute of Technology (471039) Lei Xianqing Li Hang Yang Binggan by a series of related dimensions in a certain order closed chain diagram, known as the size chain. In the dimension chain, the dimension indirectly guaranteed is the closed loop of the dimension chain; the other dimension is the component loop of the dimension chain, which can be divided into increasing loop and decreasing loop according to the influence of the component loop on the closure. As with the extreme ...
