The sprocket chain of the chain scraper conveyor has very important meaning in coal mining. The sprocket chain of the chain scraper conveyor has developed in the direction of high strength, high power, long transportation distance and high reliability.
The main transmission mode of the chain drive system of China Coal Group's chain scraper conveyor is sprocket and chain ring meshing transmission. In the actual working environment of fully mechanized coal mines, the failure rate of sprocket and chain links accounts for a high percentage of the total failure rate of scraper conveyor, mainly as follows:
Chain jams, broken chains, jumping teeth, broken sprocket teeth, crushed sprocket chain sockets, etc., the interruption of the chain will affect the normal operation of the scraper chain conveyor, resulting in a greatly reduced efficiency of the entire fully mechanized mining face. The main factors that lead to the failure of the sprocket chain of the scraper chain conveyor: the equipment is started, when the chain is jammed, and the material impacts the scraper chain, etc., have an instant impact on the chain drive system; the sprocket polygon effect on the chain The transmission system generates periodic force. During long-term operation, the key components of the chain transmission system are worn and corroded, which leads to the failure of the sprocket and chain link.
