Product Description
Product Description
Roller chain couplings have the advantages of simple structure, convenient loading and unloading, large torque transmission, and easy operation. However, there is significant wear between the chains, especially during high-speed operation when the radial motion generated by centrifugal force will accelerate their wear. Therefore, it is not suitable for use at high speeds and under impact loads, nor for the connection of vertical shafts.
When designing the overall structure of the coupling, full attention should be paid to the lubrication and dust prevention between the tooth surface and the rollers, and an outer shell should be added. In addition to dust and oil storage, it also has a protective effect. Because if the chain breaks, it may cause personal accidents.
The double row sleeve roller chain coupling has formed a standard (old standard GB6069-85, new standard GB/T 6069-2002). The transmission torque and allowable speed are 4 times and 2 times that of a single row roller chain of the same size, respectively. Because when the chain size is determined, it can accommodate 2 teeth within the width of a single row of sleeve rollers, while a double row can only accommodate 1 tooth, the tooth thickness of a single row is only half of that of a double row. So, the rollers of the double row chain are located in the grooves of the main and driven sprockets, and when subjected to force, they rotate independently without interfering with each other, reducing wear.

Standard Sizes and Specifications of Roller Chain Couplings
Roller chain couplings come in various sizes and specifications to accommodate a wide range of mechanical power transmission applications. The standard sizes and specifications of roller chain couplings typically include:
- Chain Size: Roller chain couplings are available in different chain sizes, such as 40, 50, 60, 80, 100, etc. The chain size indicates the pitch of the roller chain used in the coupling.
- Torque Capacity: The torque capacity of a roller chain coupling varies based on its size and design. Manufacturers provide torque ratings that specify the maximum amount of torque the coupling can handle without failure.
- Speed Rating: Roller chain couplings have a maximum speed rating, which indicates the highest rotational speed at which the coupling can operate safely and efficiently.
- Material: Roller chain couplings are commonly made from materials such as carbon steel, stainless steel, or nickel-plated steel, providing different levels of strength, corrosion resistance, and durability.
- Hub Type: Roller chain couplings may come with different hub types, such as pilot bore hubs or taper bore hubs, to suit various shaft connections.
- Number of Teeth: Some roller chain couplings have specific tooth configurations that can affect their performance and backlash characteristics.
- Misalignment Capacity: Manufacturers specify the maximum allowable misalignment (angular and parallel) that the coupling can accommodate to ensure reliable operation.
It is essential to refer to the manufacturer’s catalogs or product specifications to determine the exact sizes and specifications available for specific roller chain couplings. Selecting the right size and specifications depends on the application’s requirements, including torque, speed, misalignment, and environmental conditions.
Roller Chain Couplings in Applications Requiring Frequent Starts and Stops
Yes, roller chain couplings can be used in applications that require frequent starts and stops. These couplings are designed to provide reliable torque transmission and accommodate misalignments even during repetitive and rapid motion changes.
The key features that make roller chain couplings suitable for such applications include:
- Durable Construction: Roller chain couplings are typically constructed from high-quality materials, such as steel or stainless steel, which offer excellent durability and resistance to wear and fatigue.
- Shock Absorption: The flexible nature of roller chain couplings allows them to absorb shocks and vibrations that may occur during frequent starts and stops, preventing damage to connected equipment.
- Backlash Minimization: Roller chain couplings are designed to minimize backlash, which is the amount of free play between the connected shafts. This feature ensures precise and reliable torque transmission, even when starting and stopping repeatedly.
- Smooth Operation: The chain and sprocket design of roller chain couplings allows for smooth operation, reducing jarring movements during starts and stops.
- Misalignment Tolerance: Roller chain couplings can accommodate angular and parallel misalignments between shafts, which is essential in applications where frequent starts and stops may lead to slight shifts in the alignment.
- Easy Maintenance: Roller chain couplings are relatively easy to maintain, making them suitable for applications requiring frequent operation. Regular inspection and lubrication can help ensure optimal performance.
It is important to select the appropriate size and type of roller chain coupling based on the specific requirements of the application, including the expected frequency of starts and stops. Proper maintenance and monitoring of the coupling’s condition can help prolong its lifespan and ensure smooth operation even in demanding applications with frequent motion changes.
Working Principle of Roller Chain Coupling and Its Advantages
A roller chain coupling works on the principle of transferring torque between two shafts using a roller chain wrapped around sprockets on each shaft. The sprockets are connected by the roller chain, and when one sprocket rotates, it drives the other sprocket, transmitting the torque from one shaft to the other.
The advantages of roller chain couplings over other coupling types include:
- High Torque Capacity: Roller chain couplings can handle high torque loads, making them suitable for heavy-duty industrial applications.
- Compact Design: The compact and simple design of roller chain couplings allows for easy installation in tight spaces and restricted environments.
- Misalignment Tolerance: Roller chain couplings can accommodate angular, parallel, and axial misalignments between the shafts, reducing the need for precise alignment during installation.
- Shock Absorption: The inherent flexibility of the roller chain allows it to absorb shocks and dampen vibrations, protecting connected equipment from sudden loads and impacts.
- Cost-Effective: Roller chain couplings are generally cost-effective compared to other coupling types, providing an economical solution for power transmission needs.
- Wide Application Range: Roller chain couplings are used in various industries, including manufacturing, agriculture, construction, and material handling, due to their versatility and reliable performance.
- Easy Maintenance: Roller chain couplings are relatively easy to maintain and require minimal lubrication to keep the chain running smoothly.
- Long Service Life: When properly installed and maintained, roller chain couplings offer a long service life, contributing to the overall efficiency and reliability of mechanical systems.
Overall, the working principle and advantages of roller chain couplings make them a popular choice for transmitting torque between shafts in diverse industrial applications.
