胶印机偏心摆动式递纸凸轮误差分析

偏心摆动式递纸机构在胶印机中应用非常广泛。其中,递纸凸轮是递纸机构中精度要求最高的零件。它的轮廓线形状及廓形制造误差会直接影响递纸机构的工作性能。因此,对其廓形和加工误差进行研究十分必要。通过研究偏心摆动式递纸凸轮的廓形加工误差与从动件工作端递纸牙运动误差之间的关系,建立了递纸凸轮廓形误差与递纸牙运动误差传递的数学模型,确定了凸轮廓形加工误差的许用范围。

The Error Analysis for Eccentric Swing Sheet Transfer Cam of Offset Press

The eccentric swing paper transfer mechanism was widely used in offset press,and the paper transfer cam is in the highest accuracy requirements in paper transfer mechanism.The profile shape and profile errors of the cam will directly affect the sheet transfer mechanism performance that it is necessary to study.The mathematic model of the cam profile error and cam follower parameter error is built by researching their relationship.The results provided the safe range for the profile error of sheet transfer ca...
