Analysis on Sprocket Dynamics Features of Scraper Conveyer Under Performances of Chain Jammed
Abstract：The equivalent dynamics model of the sprocket driving system in the scraper conveyor established based on MSC. Dytran was applied to analyze the contact dynamics features between sprocket and chain during the chain jammed process and the max strain variation law of the sprocket was obtained. With the ＂impact-rebound＂ between the sprocket and chains, the max strain would have four small-- large--small periodical variations within 0. 06 s. With the circulated number increased, the peak of the strain would be steadily reduced. Finally with the output torque of the electric motor increased, the maximum strain would be synchronously increased. With five special lo- cation nodes selected on the chain sprocket, the variation laws of the strain, normal contact force, tangential contact force and frictional force in the chain jammed process were analyzed and obtained.
