四连杆摇摆开口机构与卵圆齿轮开口机构是丝织机上常用的平纹开口机构。本文通过分析与计算闸明这两种机构综框的运动规律,并简要介绍设计要点。这两种机构实属同一类型,前者是后者的基础。因此分析从前者开始。
Four-link swing opening mechanism and the oval gear opening mechanism is commonly used on silk weaving plain opening mechanism. In this paper, we analyze and calculate the laws of motion of the two mechanisms heald frames and briefly introduce the design points. These two institutions are of the same type, the former is the basis of the latter. So the analysis starts from the former.
