How to maintain the accessory chain of Komatsu excavator?,Excavator Track Link Made in China

The chain can play the role of traction and transmission on the excavator, and it is also a common excavator accessory. In order to be able to use for a long time, such accessories as the chain will not be deformed or rusted, so more attention should be paid to the maintenance at ordinary times.

1. Refueling and maintenance chain
Adding lubricating oil to each part of the chain can effectively reduce the wear of the chain and sprocket.
2. Tension of chain
Please confirm the tension of each chain. Too tight will increase power consumption, while too loose will easily cause the chain to fall off, so the chain should be within the correct serrated interval.

3. Maintenance when not used for a long time
After each operation, because there will be dust during the operation, it is easy to get dust and dirt on the chain, affecting the transmission. It should be cleaned regularly. You can clean it in clean diesel oil first, and then soak it in oil for about 30 minutes. The yellow sprocket is also cleaned with diesel oil when it is packed in a dry place. The butter is rusty and the sprocket is severely worn. The sprocket and chain should be replaced at the same time to ensure excellent hand feel. Do not replace the new chain or sprocket separately, otherwise it will cause poor engagement and accelerate the wear of the new chain or sprocket. When the tooth surface of the sprocket is worn to a certain extent, it shall be timely rolled (refer to the adjustable sprocket tooth surface) to extend the service life.Excavator Track Link Made in China
4. Chain type
There are many types of chains, which can be divided into: drive chain, drive chain and tension chain. According to the structure of the chain, it can be divided into roller chain, sleeve chain, plate chain, nylon chain, scraper chain, ring chain, etc.
5. Chain structure
Most chains consist of chain plates, chain pins, bushings and other parts. Other types of chains can only make different changes to the chain plates according to different needs. Some are equipped with scrapers on the chain plates, some are equipped with guide bearings on the chain plates, and some are equipped with rollers on the chain plates. These are modifications used in different applications.
6. Main smooth parts of chain
Generally, the smooth part of the chain is mainly sprocket, roller chain, sprocket chain and shaft chain. Because of the different structure of the chain, the smooth part of the chain may also change. However, in most chains, the smooth parts are mainly sprocket and roller chain, sprocket chain and shaft chain. Because the gap between the shaft and sleeve of the chain is very small, it is difficult to smooth it.
For the ring like chain, special maintenance is not required in daily life, but the use of lubricant is still necessary. The lubricating oil used must ensure good permeability, otherwise it will not have a good lubrication effect on the shaft and shaft sleeve. When the chain is in use, the lubricating oil will be thrown off due to the action of high speed, while at low speed, the lubricating oil will drop due to the action of gravity. Therefore, the lubricant used should have good adhesion and be able to adhere firmly to the surface.Excavator Track Link Made in China
