In practical applications, there are not only requirements for the status of the Coupling chains themselves, but also strict requirements for the matching between them and the sprocket, otherwise it will cause the corresponding failure or harm. As far as Coupling chains are concerned, there are mainly requirements for their tightness.

The Coupling chains should not be too tight or too loose, because once the Coupling chains are too tight, it will form a large forced 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, making the single side of the force larger, easy to heat damage.

In this case, even if the Coupling chains are not broken, the gap will increase in a short period of time. After the bearing clearance increases, the task straightness of the countershaft is destroyed, and the needle roller bearing will soon be damaged as a result. More seriously, this damage can be transferred from the Coupling chains to the gearbox.

Let's take a look at the hazards of Coupling chains and sprockets if they are not well matched. First of all, if the two are improperly installed, it will increase the wear degree of the chain and sprocket and reduce the service life of the chain sprocket. Especially when the pitch of the chain and the pitch of the sprocket are unreasonable, it will cause the phenomenon of skipping teeth.

To prevent this from happening, observe the Coupling chains for dead joints and ensure that each chain pin and sleeve move freely between each other. At the same time, it is also 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, and the sprocket will cause the pin spring to fall off if it deviates from the chain side.

Another point is that the Coupling chains and sprockets must be moderate, not too tight and too loose; And ensure that the chain operates normally without noise; Be sure to oil on time, and regular maintenance can also help extend the service life of Coupling chains.
