In actual applications, there are not only requirements for the state of the non-standard chain itself, but also strict requirements for the matching between it and the sprocket, otherwise it will cause corresponding failures or hazards.As far as non-standard chains are concerned, there are mainly requirements for their tightness.

    It is required that the non-standard chain cannot be too tight or too loose, because once the non-standard chain is too tight, a larger compulsive holding moment will be formed between the countershaft and the rear wheel buffer body, and the influence of this moment Under the circumstance, the mission characteristics of the bearing will be destroyed, making one side more stressed and easy to be damaged by heat.

    At this time, even if the non-standard chain is not damaged, the gap will increase in a short time.After the bearing clearance increases, the straightness of the countershaft will be destroyed, and the needle roller bearing will soon be damaged as a result.What's more serious is that this kind of damage will be transferred from the non-standard chain gear to the gearbox.

    Let's take a look at the harms of non-standard chain and sprocket. First of all, if the two are installed improperly, it will increase the degree of wear of the chain and sprocket and reduce the service life of the chain sprocket.Especially when the chain pitch and the sprocket pitch are unreasonably proportioned, it will cause tooth skipping.

    In order to prevent the occurrence of similar problems, observe whether there are dead links on the non-standard chain, and ensure that each link of the chain can move freely between the pin shaft and the shaft sleeve.At the same time, it is necessary to ensure that the chain and the sprocket are on a certain parallel line. The sprocket is on the center line of the chain. If the sprocket deviates from one side of the chain, it will cause the pin circlip to fall off.

    Another point is that the tension of the non-standard chain and sprocket must be moderate, not too tight or too loose; and to ensure that the chain runs normally without noise; must be oiled on time, and frequent maintenance can also help the life of the non-standard chain Extension.
