【摘要】 离合压机构直接影响到印刷机工作的稳定性。从双面胶印机的特点出发 ,设计出一种由上下橡皮滚筒完成动作的离合压机构。通过选择三次多项式的运动规律 ,分析离合压机构运动过程的时序 ,求出了离合压凸轮的轮廓曲线。该设计方法同样适用于印刷机其它机构的设计。更多还原

【Abstract】 On off pressure mechanism makes a direct impact on the stability of an offset press. Based on a perfect offset press , a kind of on off pressure mechanism through moving upper and lower blankets is designed. After making use of 3th polynomials ,a cam curve is obtained by analyzing moving process of the on off pressure mechanism. The design approach is also suitable for the other mechanical design of offset presses.更多还原
