一种复合机构在剑杆织机改造中的设计分析

Analysis of Combined Mechanism in Improving Weaving Machine with Rapiers

分析了钢带引纬剑杆织机引纬驱动机构的改进方案,看到了复合机构在织机改造中的应用.在整机结构没有较大改动的情况下,用行星齿轮连杆复合机构,代替原来的单一连杆驱动机构.该复合机构提升了剑杆织机的性能,完全满足阔幅织物的要求.在行星齿轮连杆复合机构中,偏心距e的增加,最有助于筘幅的提高.

This thesis deals with the analysis of improved system of the steel tape rapier looms widely used, and shows the usage of combined mechanism in this reformation. When the whole weaving machine is only changed a little, through the combined mechanism, the improved weaving machine can weave the fabrics with wider reed space. In this thesis, the combined mechanism of a crank lever mechanism, which crank is driven by a diffrential gear train, has its own key factor in this design. It is the eccentric distance 'e' . Increasing the ' e' is very helpful to increase the width of the textiles.
