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.

- 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.
