| 摘 要： | 弯针机构与成圈叉机构是暗缝缝纫机的两个重要机构。前者为RSS′R空间连杆机构。后者为RRRSR空间连杆机构。本文应用影响系数法对这两个机构进行了精度分析与综合,为暗缝机新机设计确定了合理的公差尺寸。从而说明影响系数法对空间机构的精度设计是个行之有效的方法。

| Abstract: | Bend needle mechanism and looper mechanism are two important mechanisms in blind stitching machine. The former is a RSS'R spatial linkage and the latter, a RRRSR spatial linkage. In the paper, sensitive-coefficient method is used to analyse and synthesize the accuracies of the two mechanisms and to calculate the reasonable tolerances for designing the new blind stitching machine. It shows that the sensitive-coefficient method is a useful means for accuracy design of the spatial mechanism. |
