Product Description
Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.
Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc
Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.
How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

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.
Materials Used in Manufacturing Roller Chain Couplings
Roller chain couplings are typically constructed from high-quality materials to ensure durability and reliable performance. The most common materials used in their manufacturing include:
- Steel: Steel is a popular choice for roller chain couplings due to its excellent strength and resistance to wear. It can handle high torque and speed requirements, making it suitable for a wide range of industrial applications.
- Stainless Steel: Stainless steel is used when corrosion resistance is required. It is often employed in industries where the coupling is exposed to moisture, chemicals, or harsh environmental conditions.
- Cast Iron: Cast iron is known for its robustness and excellent heat dissipation properties. It is commonly used in applications where shock absorption and reduced vibrations are essential.
- Aluminum: Aluminum is a lightweight material that offers good strength-to-weight ratio. It is commonly used in applications where reducing the overall weight of the system is critical.
- Nickel-Plated: Nickel-plated roller chain couplings provide enhanced corrosion resistance, making them suitable for applications in challenging environments.
When selecting a roller chain coupling, it is essential to consider the specific requirements of the application, including torque, speed, environment, and potential exposure to corrosive substances. Choosing the right material ensures the coupling’s longevity and efficient power transmission in the intended operating conditions.
Key Design Considerations for Roller Chain Couplings in Power Transmission Systems
When using roller chain couplings in power transmission systems, several key design considerations should be taken into account:
- Torque and Power Ratings: Calculate the required torque and power ratings to ensure the roller chain coupling can handle the expected loads and prevent overloading.
- Speed: Consider the operating speed of the coupling to select a roller chain and sprocket combination that can handle the rotational speed without experiencing excessive wear or fatigue.
- Shaft Sizes: Ensure that the roller chain coupling’s sprockets are compatible with the shaft sizes of the connected equipment. Proper fit is crucial to transmit torque effectively and prevent slippage.
- Misalignment: Assess the potential misalignments between the shafts and choose a roller chain coupling that can accommodate the expected angular, parallel, and axial misalignments to reduce stress on the system.
- Service Environment: Consider the operating conditions, such as temperature, humidity, and exposure to contaminants, and select roller chain coupling materials that can withstand the environmental factors for extended service life.
- Lubrication: Determine the lubrication requirements of the roller chain coupling and establish a maintenance schedule to ensure proper lubrication and prevent premature wear.
- Space Limitations: Take into account any spatial restrictions or limitations in the installation area to select a roller chain coupling that fits within the available space.
- Alignment Maintenance: Plan for periodic alignment checks and adjustments to maintain the optimal performance of the roller chain coupling and extend its service life.
- Cost: Evaluate the budget constraints and compare the cost of different roller chain coupling options to choose the most cost-effective solution without compromising performance.
By considering these design factors, engineers can ensure that the roller chain coupling performs optimally and provides reliable power transmission in their specific power transmission systems.
