Product Description

Roller Chain(A series)

 

Product Description

Roller chain is a type of chain used for transmitting mechanical power and belongs to a type of chain drive. It is connected by a series of short cylindrical rollers and realizes power transmission by meshing with the gears of sprockets. The roller chain is composed of five structures:Inner link plate: The inner link plate is in interference fit with the sleeve. It is the inner connecting part of the chain and plays a role in connecting and supporting.Outer link plate: The outer link plate is also in interference fit with the pin shaft. It is located on the outside of the chain and is used to connect each link and maintain the shape of the chain.Pin shaft: It plays a role in connecting the inner and outer link plates, enabling the chain to form a continuous circular structure.Sleeve: The sleeve is sleeved on the pin shaft and has a clearance fit with the pin shaft. Its role is to provide support and a rotating track for the roller, reducing the friction between the roller and the pin shaft.Roller: The roller is loosely sleeved on the sleeve and can rotate freely. When the chain meshes with the sprocket, the roller contacts the tooth groove of the sprocket, which can reduce friction and wear and also relieve impact.

Features of roller chain :

1.High transmission efficiency

• Compared with belt drive, roller chain has no elastic slippage phenomenon and can maintain an accurate average transmission ratio. This means that during the transmission process, power can be transferred from the driving shaft to the driven shaft more effectively, reducing energy loss.

• This characteristic of roller chain gives it a clear advantage in occasions that require efficient transmission, such as in mechanical equipment in industrial production and in automobile engines.

2.Strong load-bearing capacity

• The structural design of roller chain enables it to withstand large loads. The chain is composed of multiple links, and each link has a certain strength and stiffness. When the chain bears a load, the load is evenly distributed on each link, thereby improving the load-bearing capacity of the chain.

• Especially in the case of low-speed and heavy-load, the roller chain can still maintain good working performance. This is because the rollers of the roller chain contact the tooth grooves of the sprocket, which can disperse the load and reduce the wear and deformation of the chain. Therefore, roller chains are widely used in fields such as lifting and transportation and mining machinery, which usually need to bear large loads.
 

3.Small load on shafts and bearings
 

• The chain does not require a large tension force, so the load acting on the shafts and bearings is relatively small. Compared with belt drive, the tension force of roller chain is smaller and will not generate excessive pressure on shafts and bearings. This reduces the wear of shafts and bearings and extends their service life.

• At the same time, the smaller load also makes the design of shafts and bearings simpler and reduces costs. In some occasions with high requirements for shafts and bearings, such as high-precision machine tools and aerospace equipment, this characteristic of roller chain is particularly important.
 

4.High reliability

• Roller chain will not slip easily like belt drive, and the transmission is reliable. The meshing between the chain and the sprocket is realized through rigid links, so there will be no slipping phenomenon during the transmission process. This ensures the stable transmission of power and improves the working reliability of the equipment.

• In addition, roller chain also has a strong overload capacity. When the equipment is overloaded, the roller chain can withstand a certain overload load without being damaged immediately. This provides a guarantee for the safe operation of the equipment.

5.Adaptability to harsh environments

• Roller chain can work normally in harsh working environments such as high temperature, humidity, and dust. The various parts of the chain are usually made of high-strength metal materials and have good corrosion resistance and wear resistance. At the same time, the structural design of the roller chain also enables it to adapt to different working environments.

• For example, in mining machinery, roller chains need to work in harsh environments such as dust and sand; in chemical equipment, roller chains need to work in corrosive media. These characteristics of roller chains enable it to maintain good working performance in various harsh environments.
