IMPACT OF LOAD ON THE CONTACT SURFACE OF COOPERATING CHAIN LINKS OF SCRAPER CONVEYORS

The article presents the impact of load on the contact surface of cooperating chain links in scraper conveyors. A finite element method (FEM) simulation was conducted for a chain operating on a sprocket, based on which stress and strain maps were determined for different load levels. The contact surface areas of the chain links and the reaction forces were also calculated depending on the load, which allowed the determination of surface pressures.
