摘要
研究电子提花机的开口传动装置的齿轮-杆组合机构运动规律,采用理论分析与计算机仿真的方法,先建立机构各构件初始位姿参数的函数关系,再通过ADAMS软件形成参数化模型.研究随齿轮传动比和两随动曲柄起始相位差变化条件下,刀箱连杆竖向运动的位姿改变.研究结果表明:当节圆直径传动齿轮大于中间轮直径以及两随动曲柄杆初始相位角相差180°时刀箱连杆竖向速度变化波动最小,能获得较为平稳的杆运动特征,为提花机传动装置提供了必要的设计依据.
In order to study the kinematic characteristics of gear-rod combined mechanism in electronic jacquard shedding transmission, using theoretical analysis and computer simulation, this study has developed a function for each component's initial pose parameter, and then built a parameter model using ADAMS. When the transmission gear ratio and the initial phase difference of servo cranks vary, the characteristics of rod's vertical pose motion are investigated. The simulation results show that the rod's vertical velocity fluctuation reaches minimum when the pinion gear's diameter of reference circle is greater than middle gear's diameter and the servo cranks' phase difference is 180 degree. This study provides a useful design basis for electronic jacquard shedding transmission.
