精梳机分离罗拉传动机构的平衡优化

Balance optimization based on detaching roller transmission mechanism of combing machine

为减小精梳机在高速运转时产生的振动,使用线性独立向量法,在对现有精梳机分离罗拉传动机构进行数学分析的基础上,运用Solidworks三维建模技术、Adams虚拟样机仿真技术和Mat Lab计算机编程技术对精梳机的分离罗拉传动机构进行研究,探讨该机构在运动过程中单个构件惯性力的大小以及在机构总惯性力中所占的比重,并比较机构在优化前后惯性力的变化情况。结果表明:定时调节盘、连杆1、偏心套、摆动臂、连杆2、摇杆、摇杆结合件产生的惯性力分别占总惯性力的比重依次为0.73%、8.01%、36.87%、38.55%、5.72%、8.75%、1.37%;通过在偏心套上添加配重的方式可使整个机构惯性力减小11.30%,有利于提高精梳机速度和降低能源消耗。

In order to reduce the vibration when the combing machine is in high-speed operation,the linear independent vector method is adopted,and based on the mathematical analysis of the existing detaching roller transmission mechanism of the combing machine, the Solidworks 3-D modeling technology,Adams virtual prototype technology and Mat Lab computer programming technology are used in studying the detaching roller transmission mechanism of the combing machine,the inertial force of the individual component and the proportion accounts for the total inertia force are discussed,and the changes of the inertial force before and after optimization are compared. The research results show that the proportions of the inertial forces generated from the timing adjustment plate,the connecting rod 1,the eccentric sleeve,the swinging arm,the connecting rod 2,the rocker and the rocker connector accounts for 0. 73%,8. 01%,36. 87%,38. 55%,5. 72%,8. 75% and 1. 37% of the total inertia force,respectively; and the way of adding the weight on the eccentric sleeve can make the total inertia force decreased by 11. 30%,and it is conducive to improve the speed of the combing machine and reduce the energy consumption.
