A basic guide to getting more life from Roller chain

 

Chains are solid and stable mechanical components that transmit energy through power from one place to another. It is most commonly used as a cost-saving component of power transmission machines for high loads and low speeds, and is often used to drive vehicle wheels, especially on motorcycles and bicycles, but also for other machines. . Flexible as a belt and as positive as a gear, the chain offers design flexibility, convenience, resistance to impact loads, simplicity of installation and reliability.

Roller chains are the most common type of chain that requires efficient and economical power transmission. Roller train units have an excellent advantage compared to other pre-calendar means. Roller chains are made of durable materials that last a long time, but there are important factors to maximize the life of the chain and minimize operating costs.

The Importance of Proper Lubrication:-

Roller chains and units should be gently protected from dust and moisture.

Effective lubrication is required to achieve optimal chain life and reduce wear. Proper lubrication not only slows down wear, but also provides hearing and dampens impact loads.

It is recommended to use good quality petroleum-based oils without additives. Some additives may leave a rubber or gloss deposit that prevents oil from entering the chain joint. Heavy oil and grease are generally too rigid to enter the surface of the chain and should be avoided.

Replace worn sprockets and check alignment:-

Worn sprockets are one of the biggest causes of premature wear. Similar to driving a wear chain on a new cogwheel, driving a new chain on a worn cogwheel increases the amount of chain load at the level of the cogwheel. Worn sprockets should be replaced as soon as possible, as the chain can wear out quickly.

Misalignment of sprockets is another aspect of initial chain wear. When replacing sprockets, check the alignment of sprockets and axles. The precise alignment of the pinion shaft and tooth surface provides a uniform load distribution across the entire width of the chain and contributes substantially to maximum lifespan. If the sprockets are not in the same plane and angled to each other, the additional force of the chain can significantly increase the wear rate.

There are also other factors that can affect the wear rate of the chain:

Inadequate chain tension:-

Tightening the chain more than necessary for the application has a direct impact on the wear rate. Therefore, to increase the life of the chain, avoid excessive tension.

Wrong Chain size:-

If you select the wrong chain size, you will not be able to deliver the target load, which may cause faster wear.

To prolong the life of the chain, the chain drive must be installed correctly and maintained regularly.
