Abstract:

In order to analyze the kinematics performance of elliptic-gear & crank-rocker weft insertion mechanism which had been proposed by the authors, kinematics mathematical models of the mechanism were established, and the corresponding analytic software was compiled. Influences of some important parameters on the kinematics characteristics of the mechanism were analyzed. A group of preferable parameters were obtained and its kinematics performance was analyzed. Comparisons of kinematics performance were done between the mechanism and the spatial four-linkage weft insertion mechanism of GTM rapier loom manufactured by PICANOL Corp. in Belgium. So the mechanism invented by the authors can meet the requirements of inserting wefts.

Key words: weft insertion mechanism, kinematics, elliptic-gear, crank-rocker

摘要：

为了分析椭圆齿轮—曲柄摇杆引纬机构的运动学特性，建立了该机构的运动学数学模型，开发了辅助分析软件，分析了一些重要参数对该机构运动学特性的影响,得到了一组较佳的参数。对该组参数下的引纬机构进行了运动分析，并和比利时PICANOL公司生产的GTM剑杆织机的空间四连杆引纬机构进行了比较，证明了椭圆齿轮-曲柄摇杆引纬机构能满足引纬要求。
