The scraper conveyor is like a drive chain, and the precision conveyor chain is also composed of a series of bearings. They are fixed by a restraining chain plate, and the positional relationship between them is very precise. Each bearing of the scraper conveyor includes a pin and a sleeve, on which chain rollers rotate. Both the pin and the sleeve have undergone surface hardening treatment, so that they can be hinged together under high pressure, and can withstand the load pressure transmitted by the rollers and the impact of engagement.
The conveyor chains of various strengths of scraper conveyors have a series of different chain link distances: the minimum chain link distance depends on the requirements of the sprocket teeth for sufficient strength, and the larger chain link distance is usually determined by the rigidity of the chain plate and the general chain Decide. If necessary, the sleeve between the chain plates can be strengthened to exceed the rated larger link distance, but a gap for removing the sleeve gap needs to be reserved in the gear teeth.
In the industrial chain, the conveyor chain is a very common chain. From the assembly line to the food industry, conveyor chains are everywhere, and conveyor chain wear is also common. The wear of the conveyor chain is caused by its fatigue use.
Long-term use and wear of the chain will cause the chain to fail and affect work efficiency. In fact, after a period of time, the chain can be reversed and the slightly worn side can be used for continued use. Regular addition of lubricating oil can also reduce the degree of wear of the scraper conveyor. Generally speaking, the failure of the conveyor chain is mainly caused by long-term use.
