What are the common types of roller chains?

A roller chain is a common transmission chain widely used in various mechanical equipment. It consists of a series of rollers and link plates, which transmit power and carry loads through the rolling of rollers. Roller chain has the advantages of simple structure, high transmission efficiency, and large load-bearing capacity, so it has been widely used in the industrial field. The following will introduce some common types of roller chains.

1. Standard roller chain

Standard roller chain is the most common type and the most widely used one. The size, spacing, and other parameters of its rollers and link plates meet international standards, so they can be used in conjunction with other standard parts and are suitable for various transmission occasions, such as machine tools, textile machinery, metallurgical equipment, etc.

2. High-strength roller chain

The high-strength roller chain is improved on the basis of the standard roller chain, increasing the size of the rollers and link plates, improving the chain's load-bearing capacity and fatigue resistance, and is suitable for occasions with large loads and harsh working environments, such as heavy machinery, mining equipment, etc.

3. High-speed roller chain

A high-speed roller chain is a roller chain specially designed for high-speed transmission. It is made of lightweight materials, which reduce the inertia and friction loss of the chain, improve the transmission efficiency and working stability, and is suitable for high-speed mechanical equipment, such as wind turbines, automobile engines, etc.

4. Silent roller chain

The silent roller chain reduces the friction and noise between the roller and the link plate by improving the structure and material of the chain. It uses special lubricants and sealing devices to reduce the noise and vibration of the chain and is suitable for occasions with high noise requirements, such as office equipment, medical equipment, etc.

5. Stainless steel roller chain

The stainless steel roller chain is a roller chain made of stainless steel. It has the characteristics of corrosion resistance, high-temperature resistance, and high tensile strength. It is suitable for humid and corrosive working environments and is widely used in food processing, chemical industry, and other industries.

6. Double-pitch roller chain

The double-pitch roller chain is a specially designed chain with a pitch twice that of an ordinary roller chain. This chain has greater flexibility and contact area and is suitable for light-load, low-speed transmission systems. It has certain applications in textile machinery, printing machinery, and other fields. Its unique design and performance meet the needs of specific occasions.

7. Hollow pin roller chain

The hollow pin roller chain adopts a hollow pin design, which not only reduces the weight of the chain but also improves the utilization rate of materials. This chain reduces costs while maintaining strength, and has certain economic benefits. Hollow pin roller chains are used in some occasions where weight and cost are required, such as some light machinery, conveyors, etc.

8. Single-row standard roller chain

As the most common type, the single-row standard roller chain has a simple structure and consists of an inner link plate, an outer link plate, a sleeve, a pin, and a roller. This chain is reasonably designed and can efficiently transmit power in various mechanical transmission systems. Due to its mature manufacturing process and relatively low cost, it has been widely used in many general-purpose machinery, such as common conveyors and elevators.

9. Multi-row roller chain

When a single-row chain cannot meet the larger load requirements, a multi-row roller chain comes into being. This chain increases the load-bearing capacity by increasing the number of rows, and each row is fixed by a special connector to ensure that each row of chains runs synchronously. Multi-row roller chains are often used in heavy-load environments, such as large cranes, mining machinery, etc. Their strong carrying capacity and reliable performance make them an ideal choice for these fields.

10. Roller chain with seals

In order to adapt to harsh working environments such as humidity and dust, roller chains with seals are designed. A seal is added between the sleeve and the pin of this chain to effectively prevent dust and moisture from entering and extend the service life of the chain. Roller chains with seals are widely used in agricultural machinery, construction equipment, and other fields, and their excellent environmental adaptability and durability are highly praised.

In short, as a common transmission chain, roller chains have many types, and the appropriate type can be selected according to different working environments and needs. Whether it is a standard roller chain or a special environment roller chain, they all play an important role in mechanical transmission and improve the transmission efficiency and reliability of mechanical equipment. With the continuous advancement of science and technology, the types and performance of roller chains are also constantly innovating and improving to meet the needs of different industries.
