The non-standard chain is a very common type of chain now. Compared with general scraper chain and roller chain, the non-standard chain is simpler, can be processed and manufactured according to requirements, and can meet the use requirements of any mechanical equipment. But why can’t non-standard chains be pulled too tightly when in use? China chain supplier(GETECHAIN) will explain this problem.

Starting from the definition of the non-standard chain, it is a chain manufactured according to the size of special mechanical gears. It does not conform to the size standard defined in the standard, but the quality is the same and the material is the same. Because it is designed according to different machines, some product drawings are reinforced with firmware, such as baffles, guard plates, etc.

At present, non-standard chains have been widely used, including powder metallurgy sintering furnace, food machinery, heat treatment production line, annealing furnace for glassware and brazing furnace. As well as petrochemical, drying, electronics, various kilns, and other industrial auto production line.

The reason why the non-standard chain cannot be pulled too tightly when it is used is that its specification, once pulled too tightly, will form a larger coercive restraining moment between the countershaft and the rear wheel buffer body. Under the influence of this moment, the task characteristics of the bearing will be destroyed, and one side will be stressed greatly, which is easy to heat and damage. Even if it is not damaged, the gap will be enlarged in a short time.

Moreover, this has something to do with the characteristics of its production and manufacture. If the shaft of the non-standard chain that is pulled too tightly bears too much force and cannot be used well, it will cause a series of problems to the non-standard chain and lead to damage to the non-standard chain. There is a problem of fracture. Therefore, in order to better use and protect the non-standard chain, the non-standard chain cannot be pulled too tightly.
