When the chain scraper conveyor is overloaded during use, it will produce varying degrees of impact energy on the chain plates, link links, circular chain, etc., which will increase the dynamic tension of the entire conveyor chain, making the strength of the conveyor chain weak Parts are severely deformed or broken. Therefore, the chain scraper conveyor must be used strictly in accordance with the operating rules.
In the maintenance work of the scraper chain conveyor, there was a problem that the shaft sleeve could not be removed after the shaft sleeve was locked, indicating that this is the influence of the sliding bearing radial clearance on the bearing overheating failure. This proves that the radial clearance of sliding bearings is very important, too large or too small are extremely harmful.If the gap of the sliding bearing of the chain scraper conveyor is too small, it is difficult to form a lubricating oil film, so that the frictional heat is not easily taken away, and the phenomenon of bearing overheating is prone to occur, which is the root cause of the shaft holding. However, if the gap is too large, it will also reduce the machine's operating accuracy, cause severe vibration and noise, and even cause tile burning accidents.
Each of the causes of damage to the scraper chain conveyor is not just for one component, it will affect the entire chain conveyor system, but the damaged surface will only occur in the weaker parts. Therefore, it is necessary to comprehensively consider the reasons for the failure of the conveyor chain during the operation of the chain scraper conveyor to improve the operational reliability of the conveyor equipment.
