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.

What are the common materials used in chain couplings?

Chain couplings are commonly made from various materials that offer the necessary strength, durability, and wear resistance required for transmitting torque between shafts. The choice of materials depends on factors such as the application requirements, operating conditions, and the specific design of the coupling. Here are some common materials used in chain couplings:

• Steel: Steel is one of the most widely used materials for chain couplings. It offers excellent strength, toughness, and resistance to wear and fatigue. Carbon steel and alloy steel are commonly used, with alloy steel providing enhanced properties such as higher tensile strength and improved corrosion resistance.
• Stainless Steel: Stainless steel is chosen for chain couplings when corrosion resistance is a critical requirement. It offers good mechanical properties along with resistance to rust and corrosion, making it suitable for applications in harsh environments or where exposure to moisture or chemicals is present.
• Cast Iron: Cast iron is occasionally used for chain couplings, particularly in applications where cost-effectiveness and moderate strength are important factors. Cast iron provides good wear resistance and can withstand moderate loads and operating conditions.
• Bronze: Bronze is utilized in certain specialized chain couplings, especially in applications where self-lubrication and high resistance to corrosion are required. Bronze has good friction properties and can operate in conditions where lubrication may be limited or unavailable.
• Plastics: In some cases, certain plastics, such as nylon or polyurethane, are used for chain coupling components like chain guides or protective covers. Plastics offer low friction, noise reduction, and resistance to chemicals, making them suitable for specific applications.

It's important to note that the materials used in chain couplings may vary depending on the specific manufacturer, coupling design, and application requirements. It is recommended to consult the manufacturer's specifications and guidelines to determine the appropriate materials for a particular chain coupling.

Additionally, in some cases, chain couplings may incorporate a combination of different materials, such as steel for the sprockets and roller chain, and elastomers for the flexible elements. This hybrid construction allows for optimized performance, balancing strength, flexibility, and damping characteristics.

Overall, the selection of materials for chain couplings is crucial to ensure reliable and efficient power transmission while considering factors such as load capacity, operating conditions, and the desired service life of the coupling.

Can chain couplings accommodate angular misalignment?

Yes, chain couplings are designed to accommodate a certain degree of angular misalignment between the connected shafts. Angular misalignment refers to the situation where the axes of the two shafts are not perfectly aligned and form an angle with each other.

Chain couplings are flexible in nature, and their design allows for some degree of angular displacement. The flexibility is primarily provided by the roller chain, which can bend and adjust to a certain extent to accommodate the misalignment. This flexibility helps to reduce the stress on the coupling components and allows for smoother operation even in the presence of angular misalignment.

However, it is important to note that chain couplings have limitations in terms of angular misalignment. Excessive angular misalignment beyond the specified limits can lead to increased stress, accelerated wear, and potential coupling failure. The manufacturer's specifications and guidelines should be followed to ensure that the angular misalignment remains within the acceptable range for the specific chain coupling being used.

Regular inspection and maintenance of the chain coupling are also essential to identify and address any misalignment issues. If significant angular misalignment is detected, corrective measures should be taken, such as realigning the shafts or considering alternative coupling options that are better suited for the specific misalignment requirements.

It is worth mentioning that chain couplings are more tolerant of angular misalignment compared to some other types of couplings, such as rigid or gear couplings. However, it is still important to strive for proper alignment during installation and minimize any excessive misalignment to ensure optimal performance, reliability, and longevity of the chain coupling and the connected machinery or equipment.
