Chain scraper conveyor sprocket chain has very important significance in the mining of coal mines. The scraper conveyor sprocket chain has developed towards high strength, high power, long transport distance and high reliability. The scraper conveyor chain drive The main transmission mode of the system is sprocket and chain ring meshing transmission. In the actual working environment of fully mechanized coal mining, the failure rate of the sprocket and chain ring accounts for a high ratio of the total failure rate of the scraper conveyor, mainly due to the following phenomena:
Chain scraper conveyor chain, broken chain, jumping teeth, sprocket broken teeth, sprocket chain socket crushing, etc., the interruption of the chain will affect the normal operation of the scraper conveyor, resulting in greatly reduced work efficiency of the entire fully mechanized mining face . The main factors that lead to the failure of the sprocket chain of the scraper conveyor: the equipment has a momentary impact on the chain transmission system during the startup process, when a chain jam occurs, and the material impacts the scraper chain; the polygonal effect of the sprocket on the chain transmission The system generates cyclic forces, and the key components of the chain drive system are subject to wear and corrosion during long-term work, leading to the failure of the sprocket chain.
