0 is used to solve the problem that the user interface can not respond to the other operation of the user for the complicated optimal algorithm, which is applied to implement the parametric design according to the optimal theory for a kind of speed changeable sheet-fed mechanism based on gear-shaft combinative mechanism.

Speed-shifting mechanism is one of the key components of sheet feeder on sheet-fed printer or die-cutter, whose working performance influences the stability of paper delivery.

Based on the concept of variable input speed mechanisms, this paper presented an inverse kinematic method for designing variable input speed mechanisms driven through noncircular gear drives.

Optimization of Feeder in Offsetting Imprinter and Simulation Research;

In this paper,by using the kinematic equation and torque balance equation of the differential gear train,the power flow of the differential speed change mechanism of the NGW type and the relationship among its four kinds of output rotating speeds are analyzed and the design method of this mechanism is obtained,and finally the whole design and calculation process is exemplified.
