Chain

Classification of chains

Chains are generally divided into four categories according to their functions, namely transmission chains, conveyor chains, drag chains and special special chains.

Transmission chains are divided into ductile chains, roller chains, and chain chains. Conveying chains are divided into long-pitch conveyor chains, short-pitch roller conveyor chains, double-speed conveyor chains, and double-pitch roller conveyor chains. Leading chains are divided into fishing chains, binding chains, etc .; special special chains are chains with special purposes, such as chainsaw chains for logging, agricultural chains, and sewage treatment chains.

Understand the tightness of the chain

If the chain is too tight, it will increase the power consumption and the bearings are easy to wear; if the chain is too loose, it will easily jump off the chain. The appropriate tightness of the chain is: lifted or pressed from the middle of the chain, the center distance between the two sprockets is about 2% -3%. The new chain is too long or extended after use, and it is difficult to adjust. Depending on the situation, the chain links are removed, but it must be an even number. The chain link should pass through the back of the chain, the locking piece is inserted outside, and the opening of the locking piece should face the opposite direction of rotation.

What to do when the chain drive is tight and loose

1. Generally speaking, it is caused by the wear of the gear. Due to the deviation of the tooth pitch and the small batch processing, it is difficult to ensure the actual effect, including the diameter and roundness.

2. Once the pitch of the chain is deviated, it can be improved by replacing the chain. It should be noted that changing a few more to achieve the best effect.

How to use and maintain the chain

1. When the chain is enabled, first check whether the chain is operating normally and the tightness of the saw chain is normal.

2. Remember to close the chain brake before starting to stop the chain. This is to prevent danger during startup. But remember to loosen the chain brake before work, otherwise the bearing will be damaged.

3. When the chain rotates, be careful not to cause friction with the ground or other objects.

4, the chain should be oiled in time, rust-proof paint, etc., and once the chain is rusted, it should be replaced in time to improve work efficiency.

5. The chain should be inspected and maintained frequently. In the case of broken or disconnected chains, it should be repaired in time, and the cause should be identified.
