摘要
压印滚筒转动平稳性是印刷机械的一个关键技术指标,共轭凸轮是印刷机主传动系统中的主要控制机构。为了提高转动平稳性,对一款印刷机中原有的余弦凸轮进行了改进设计,建立了满足五次多项式运动规律的凸轮轮廓曲线数模。应用Pro-E建立了印刷机的三维装配模型,然后在ADAMS中对改进前后的两种印刷机传动系统模型进行了运动学仿真,并以滚筒转动速度平稳性为目标,分析比较了两种模型的运动性能特点。
Rotational stability of embossing roller is a key technical specification for the printing machinery, and conjugate cam is the important control of the main transmission system. In order to enhance the rotational stability,the improved design of conjugate cam was established to meeting the five polynomial equation of the math model,replacing the original cosine cam in the printing machinery. Application of Pro-E to establish a printing machinery assembly of three-dimensional model,then the kinematics simulation was carried for the two transmission system（improve pre- and post- ） ,and the kinematics characteristics were analyzed and compared,taking rotational stability as objective.
