Coal mining scraper conveyor sprocket assembly wear is a common and unavoidable phenomenon for each unit of use. Today I will take you to understand which factors are mainly responsible for the wear of the lower sprocket assembly.
Coal mining scraper sprocket component wear can be divided into normal wear and abnormal wear.
Normal abrasion: Generally, after being put into use, the sprocket body and the socket on the sprocket shaft end are worn, because friction occurs when the sprocket body and the chain mesh with the chain. Generate friction. When the sprocket body and socket are severely worn, it is recommended to change the installation direction of the sprocket, change the bearing surface, and extend the service life. When the chain sockets on both sides are severely worn, it is recommended to replace the sprocket (maintenance or make a new one) to avoid skipping and jamming and damage to the remaining parts and affecting normal production.
Abnormal wear: 1. Overload operation: The underground transportation volume exceeds the factory-designed transportation volume, causing excessive load on the conveyor, increasing the wear of the accessories, and may also cause the scraper to break and the chain to break. 2. Improper operation: Failure to perform routine failure prevention and routine maintenance; failure to clean up debris on the conveyor in a timely manner; failure to timely check and resolve when problems are found, and to continue working. 3. Underground environmental factors: The underground environment is harsh, and effective protection measures have not been taken when encountering coal gangue.
