Rotational stability of embossing roller is a key technical specification for the printing machinery,and conjugate cam is the important control of the main driving system.In order to enhance the rotational stability,the improved design of conjugate cam is made to meet the quintic polynomial equation of the mathematical model,replacing the original cosine cam in the printing machinery.Aided with simulation Automatic Dynamic Analysis of Mechanical Systems(ADAMS)software,the whole mechanical system model is built and dynamic simulation is carried for the two driving systems(the improved and the original).The key component's dynamic characteristics,especially contact force's change and influence are studied and the kinetic characteristics of the two systems,are analyzed and compared,which proves the improved system more stable in rotation.
