The chain is often damaged or over-tightened during use, which will lead to a shortened chain life. Today, I will come to analyze the reasons for the chain damage and the tightness of the chain for everyone!

Chain

Causes of chain damage

1.Friction

During the use of the chain, there will be constant friction between the chain ring and the sprocket, which will cause the chain to wear, deform and reduce the strength. In such cases, the chain will break if it is strongly impacted. In addition, if the material and manufacturing quality of the chain do not meet the standard requirements, it will be more likely to cause this kind of situation.

2.Big impact damage

When subjected to an instantaneous large impact load, the chain is easily deformed, and it is very easy to break the chain at this time.

3.Fatigue failure

If the cyclic load is applied for a long time, the chain will be fatigued and broken.

4.Surface defects

If the chain itself has surface defects, it will continue to deepen after the cracks are generated, until a broken chain situation occurs.

Why the chain is too tight

1. Do not understand the common sense of chain maintenance. Non-professionals will adjust the chain by themselves.

2. Due to the severe wear of the chainring chain, sometimes the chain is temporarily tightened to maintain the vehicle driving.

3. Sometimes the eccentric sprocket is mistakenly installed on the motorcycle, causing the chain to loosen and loose.

Regardless of which of the above causes the chain to be adjusted too tightly, it will greatly reduce the service life of the chain and the chainring. When the chain is adjusted too tightly, the contact pressure with the gear plate will increase, which will cause the chain to be easily stretched, the link plate will be easily deformed or broken, and the chain rollers will be easily broken. Of course, too loose a chain is not good.

Technical requirements of the chain

1. Good reliability and maintainability. The chain must be resistant to corrosion and high temperatures, and tolerant of special environments.

2. Good abrasion resistance. When the chain works, generally the number of sprocket teeth is small, and the angle of inflection between chain links is relatively large.

3. Light weight but high strength. The weight of a chain is usually proportional to the load on the chain. An overweight chain will increase the tension in the chain and limit its ability to work.

4. The resistance to sliding or rolling should be small. Many chains slide on the track or the rollers support rolling forward, or the resistance to rolling is small, which can improve the use efficiency and life of the chain.

5. Strong impact resistance. Conveyors with uneven loads or conveyors running at high speeds tend to produce impact loads in many cases, so the chain must have strong impact resistance.
