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.

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.

What are the key components of a chain coupling?

A chain coupling consists of several key components that work together to transmit power and accommodate misalignments. Here are the main components of a chain coupling:

• Sprockets: Sprockets are the toothed wheels that engage with the chain. They are typically made of steel or other durable materials and have specially designed teeth that mesh with the chain rollers. The sprockets provide the driving and driven connections, transmitting torque from one shaft to another.
• Roller Chain: The roller chain is a series of interconnected links with rollers between them. It is looped around the sprockets, with the rollers engaging with the sprocket teeth. The roller chain transfers the rotational motion from the driving sprocket to the driven sprocket, allowing power transmission between the shafts.
• Connecting Pins: Connecting pins are used to join the links of the roller chain together, forming a continuous loop. These pins are inserted through the pin holes in the chain links and secured with retaining clips or other fasteners. They ensure the integrity and strength of the chain.
• Bushings or Bearings: Bushings or bearings are used to support the shafts and allow them to rotate smoothly within the chain coupling. They are typically inserted into the bores of the sprockets and provide a low-friction interface between the shaft and the coupling components.
• Guard or Cover: In some chain couplings, a guard or cover is added to enclose the sprockets and chain. This serves as a protective barrier, preventing contact with moving parts and reducing the risk of accidents or injuries. The guard or cover also helps to contain lubrication and protect the chain from contaminants.
• تشحيم: Lubrication is essential for the smooth operation and longevity of a chain coupling. Proper lubrication reduces friction, wear, and noise. Lubricants, such as chain oil or grease, are applied to the chain and sprockets to minimize frictional losses and prevent premature wear.

These components work together to provide a reliable and efficient power transmission in chain couplings. The sprockets engage with the roller chain, and as one sprocket rotates, it drives the chain, causing the other sprocket and the connected shaft to rotate. The roller chain and its components, along with lubrication, allow for flexibility and compensation of misalignment between the shafts.
