Sprocket/Chain 25 Series（04C）

Frequently asked questions about this product

1. What is the relationship between the number of sprocket teeth and the number of chain sections?

The number of chain sections is usually selected as an even number, while the number of sprocket teeth should be an odd number that is coprime with the number of chain sections to maintain uniform wear.

2. How to choose the chain pitch under different center distances?

Too small a center distance will increase the load on each gear tooth, resulting in increased wear and tooth skipping; too large a center distance may cause up and down vibration. The center distance is generally initially set to (30~50)p, and the maximum can be amax=80

3. How to select the sprocket chain under high speed and impact?

In addition to paying attention to the chain strength to meet the load usage, in high-speed and high-impact environments, the number of sprocket teeth should be at least 25 to ensure the smoothness of the transmission.

4. What do the A B series of chains mean? Can the two be matched?

There are two standards for standard roller chains. The standard chains currently sold on the market are A series and B series. A series is the American and Japanese standard, and B series is the European standard. It should be noted that the two cannot be matched with each other.

5. Does the chain drive need to be lubricated?

The lubrication of the chain drive is very important, especially for high-speed and heavy-load chain drives. Good lubrication can alleviate impact, reduce wear and extend the life of the chain.

6. When I need multiple sprockets to be used coaxially, I need multiple sprockets to be driven synchronously. How should I choose?

Due to the process and the preparation of different production batches, it is impossible to ensure that the keyway positions of all sprockets are consistent. Therefore, when multiple sprockets need to be used synchronously, you need to note the working conditions after the model when placing an order. For example: VLD02-35-16-D14 (keyways are paired in pairs, and sprockets are used synchronously)
