In order to reduce the impact load of the chain magazine during operation, decrease the influence of the polygon effect, and make the transmission more stable, the method of a large-tooth sprocket and a small-pitch chain is used to design the magazine. The three-dimensional modeling for racks, sprocket wheels, boxes, and rails is established based on Creo, and the overall architecture model of the magazine is constructed. Using Lagrange equation of the second kind, the dynamic differential equations are given. With the multi-body dynamics simulation software RecurDyn simulating the kinematics of the magazine, the dynamic response of the tight-edged parts and the loose-edged parts from the magazine is obtained at the start-up stage. The results show that the magazine has a relatively stable transmission, and meets the design requirements.
