In the power transmission system of vertical binder, the input power not only meets the need to provide two continuous power for the double-gathering mechanism of the binder to turn opposite to each other, but also provides intermittent motion power for the wire-feeding and bundling mechanism, which puts forward high requirements for design of the transmission system. In this paper, a double output chain drive system is designed. The SolidWorks is used to build a three-dimensional solid model and the Adams software is used to analyze the kinematics of the system, which verifies the feasibility...
