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.

How does the chain size affect the performance of a chain coupling?
The chain size has a significant impact on the performance of a chain coupling. The size of the chain refers to the physical dimensions of the roller chain used in the coupling, including the pitch, roller diameter, and width. Here are some key ways in which the chain size affects the performance of a chain coupling:
- Torque Capacity: The chain size directly affects the torque capacity of the chain coupling. Larger chain sizes are generally capable of transmitting higher torque loads due to their increased contact area and greater strength. Smaller chain sizes, on the other hand, have lower torque capacities and are suitable for applications with lighter torque requirements.
- Speed Capability: The chain size also influences the speed capability of the chain coupling. Larger chains can typically handle higher rotational speeds without experiencing issues such as excessive vibration or centrifugal forces. Smaller chain sizes may have limitations in terms of maximum allowable speeds and may not be suitable for high-speed applications.
- Service Life: The selection of an appropriate chain size is crucial for achieving the desired service life of the chain coupling. If the chain is undersized for the application, it may experience premature wear, fatigue, and ultimately fail under the operating conditions. Conversely, using an oversized chain may result in unnecessary costs, increased weight, and reduced efficiency.
- Space Constraints: The physical size of the chain can also impact the overall dimensions and installation requirements of the chain coupling. Larger chain sizes may require more space for proper installation, including clearance for the chain links and sprockets. In applications with limited space, choosing a smaller chain size may be necessary to ensure proper fit and operation.
- Compatibility: The chain size should be compatible with the sprockets and other components of the chain coupling. It is important to ensure that the chain and sprockets are designed to work together, with matching dimensions and tooth profiles. Using an incompatible chain size can lead to poor engagement, increased wear, and reduced overall performance.
When selecting the appropriate chain size for a chain coupling, it is essential to consider the specific requirements of the application, including torque, speed, space limitations, and compatibility with other components. Consulting the manufacturer’s recommendations and guidelines is crucial to ensure the optimal chain size selection for the desired performance, reliability, and longevity of the chain coupling.
What is the maximum torque capacity of a chain coupling?
The maximum torque capacity of a chain coupling can vary depending on several factors, including the size and design of the coupling, the type and quality of the components used, and the application requirements. It is important to refer to the manufacturer’s specifications and guidelines for the specific chain coupling being used. These specifications typically provide the maximum torque capacity or the maximum allowable torque for the coupling.
The maximum torque capacity is usually expressed in torque units, such as Newton-meters (Nm) or foot-pounds (ft-lb). It represents the maximum amount of torque that the chain coupling can transmit without exceeding its design limits or risking premature failure.
When selecting a chain coupling, it is crucial to consider the torque requirements of the application and choose a coupling with a sufficient torque capacity. Factors such as the power requirements, operating conditions, and misalignment tolerance should be taken into account to ensure that the selected coupling can handle the required torque.
It is important to note that exceeding the maximum torque capacity of a chain coupling can lead to various issues, including accelerated wear, excessive stress on the components, and potential coupling failure. Therefore, it is recommended to always operate the chain coupling within its specified torque limits to maintain its reliability and longevity.
For accurate and precise information regarding the maximum torque capacity of a specific chain coupling, it is necessary to consult the manufacturer’s documentation or contact the manufacturer directly. They can provide detailed information based on the specific design and specifications of the coupling.
How does a chain coupling work?
A chain coupling works by connecting two rotating shafts using a roller chain and sprockets. The sprockets have teeth that engage with the rollers of the chain, creating a positive drive mechanism.
When the first shaft rotates, it drives the sprocket attached to it. The engaged chain then transfers the motion to the second sprocket and the second shaft, causing it to rotate as well.
The chain coupling design allows for flexibility and misalignment compensation. In the presence of angular misalignment between the shafts, the chain can accommodate the deviation by flexing and adjusting its position on the sprockets. Similarly, if there is parallel misalignment or axial displacement, the chain coupling can flex and adjust to maintain proper engagement and transmit torque between the shafts.
The engagement between the sprocket teeth and the chain rollers ensures a positive drive, meaning that the torque from the driving shaft is efficiently transferred to the driven shaft. This makes chain couplings suitable for applications where high torque loads need to be transmitted.
Proper lubrication is essential for the smooth operation and longevity of a chain coupling. Lubricants such as oil or grease are applied to the chain and sprockets to reduce friction and wear. The lubrication helps prevent heat buildup and ensures the chain and sprockets rotate smoothly, minimizing power losses and extending the lifespan of the coupling.
In summary, a chain coupling operates by using a roller chain and sprockets to connect two rotating shafts. The engaged chain transfers torque from the driving shaft to the driven shaft, while accommodating misalignment between the shafts. The positive drive mechanism and the flexibility of the chain make chain couplings effective in transmitting high torque loads while allowing for smooth and reliable power transmission.
