Abstract:In view of the contradiction between the demand for torque at large roll diameter and the demand for rotational speed at small roll diameter of the rewinder retiring roller， resulting in excess of motor power configuration， the variable reduction ratio design and power configuration model were proposed. Firstly， the optimization scheme and principle of variable reduction ratio structure were analyzed. Then， the power configuration method was analyzed and the corresponding parameters were calculated， followed by the system working process and reduction ratio switching control process were explained. Finally， the effects of energy saving and cost reduction of variable reduction ratio were explained. Compared with the traditional fixed reduction ratio structure， this program reached the purpose of configuration optimizing， resource and cost saving.
