Product Description

Custom Precision Clamping Type Flexible Disc Coupling Jaw Coupling Oldham Coupling with CNC Machining

Product Description

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.

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.

It is widely used in metallurgical steel rolling, wind power, hydropower, mining, engineering machinery, petrochemical, lifting, paper making, rubber, rail transit, shipbuilding and marine engineering and other industries.

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.

clamp coupling

Can Clamp Couplings Be Used in High-Temperature or Corrosive Environments?

Yes, clamp couplings are designed to be versatile and can be used in a wide range of environments, including high-temperature and corrosive conditions. However, their suitability depends on the specific material and coating used in the construction of the coupling.

In high-temperature environments, clamp couplings made from materials such as stainless steel or high-temperature alloys are commonly used. These materials have excellent heat resistance and can withstand elevated temperatures without losing their structural integrity. It is essential to choose a clamp coupling with a temperature rating that exceeds the operating temperature of the application to ensure safe and reliable performance.

In corrosive environments where exposure to chemicals, moisture, or other corrosive substances is a concern, selecting a corrosion-resistant material is critical. Stainless steel clamp couplings, particularly those made from 316-grade stainless steel, are widely used in such conditions due to their superior corrosion resistance. For more aggressive corrosive environments, special coatings or surface treatments can be applied to further enhance the coupling’s resistance to corrosion.

It is essential to consider the specific requirements of the application when selecting a clamp coupling for use in high-temperature or corrosive environments. Factors such as temperature, humidity, exposure to chemicals, and the presence of abrasive substances should be taken into account. Consulting with coupling manufacturers or industry experts can help in choosing the most suitable clamp coupling for the intended application.

Comparison of Clamp Couplings with Jaw Couplings and Bellows Couplings

Clamp couplings, jaw couplings, and bellows couplings are all common types of couplings used in mechanical power transmission. Each type has its unique design and features, making them suitable for different applications. Here’s a comparison of these couplings:

  1. Design:

Clamp Couplings: Clamp couplings consist of a split hub with screws that tighten around the shafts, providing a secure and balanced connection.

Jaw Couplings: Jaw couplings have two hubs with curved jaws that interlock to transmit torque. They can accommodate a certain degree of misalignment.

Bellows Couplings: Bellows couplings use a thin-walled metallic bellows to transmit torque while compensating for misalignment. They are typically more flexible than clamp couplings and jaw couplings.

  1. Misalignment:

Clamp Couplings: Clamp couplings can handle a small amount of angular misalignment but are better suited for applications with precise alignment.

Jaw Couplings: Jaw couplings can accommodate angular and axial misalignment but have limitations on radial misalignment.

Bellows Couplings: Bellows couplings can handle higher levels of misalignment, including angular, radial, and axial misalignment.

  1. Vibration Damping:

Clamp Couplings: Some clamp couplings can provide a degree of vibration damping due to their material properties, but they are not specifically designed for this purpose.

Jaw Couplings: Jaw couplings have some vibration absorption capabilities due to the flexibility of the elastomeric spider element.

Bellows Couplings: Bellows couplings are known for their excellent vibration damping characteristics, making them suitable for applications where vibration isolation is critical.

  1. Backlash:

Clamp Couplings: Clamp couplings typically have minimal backlash, providing precise torque transmission.

Jaw Couplings: Jaw couplings have a small amount of backlash due to the clearance between the jaws and the spider element.

Bellows Couplings: Bellows couplings have negligible backlash, making them suitable for applications requiring high precision.

  1. Temperature and Environment:

Clamp Couplings: Clamp couplings are generally suitable for a wide range of temperatures and environments, depending on the material used.

Jaw Couplings: Jaw couplings are versatile and can operate in various conditions, but their elastomeric elements may have temperature limitations.

Bellows Couplings: Bellows couplings can withstand high temperatures and are often used in demanding environments.

  1. Cost:

Clamp Couplings: Clamp couplings are often more cost-effective compared to jaw couplings and bellows couplings.

Jaw Couplings: Jaw couplings are generally affordable and offer a good balance between cost and performance.

Bellows Couplings: Bellows couplings are more expensive than clamp couplings and jaw couplings due to their precision and high-performance characteristics.

When selecting a coupling, it is essential to consider the specific requirements of the application, including torque, misalignment, precision, and environmental factors. Consulting with coupling manufacturers or engineers can help in choosing the most suitable coupling for a particular mechanical system.

What is a Clamp Coupling and How Does it Work?

A clamp coupling is a type of mechanical coupling used to connect two shafts together to transmit torque and rotational motion between them. It is a simple and effective way of joining shafts in various mechanical systems. The main components of a clamp coupling typically include two hubs and a center section.

Working Principle:

The clamp coupling works on the principle of frictional force and mechanical interference fit. Here’s how it functions:

  1. Hub Assembly: Each end of the shaft has a hub, which is a cylindrical component with a bored hole that matches the shaft diameter. The hubs may have keyways or splines to provide additional torque transmission.
  2. Center Section: The center section of the coupling sits between the two hubs. It is often a split cylindrical sleeve with threaded holes on its outer surface.
  3. Clamping: To assemble the clamp coupling, the two hubs are placed on the respective shafts, and the center section is inserted between them. Then, bolts are inserted through the holes in the hubs and screwed into the threaded holes of the center section. As the bolts are tightened, the center section is drawn inward, creating a compressive force on the shafts and the hubs, thus firmly holding them together.
  4. Frictional Connection: The clamping force between the center section and the shafts creates a frictional connection. This frictional force allows the coupling to transmit torque and rotational motion from one shaft to the other.

Advantages:

Clamp couplings offer several advantages:

  • Easy and quick installation, requiring minimal tools and no special skills.
  • Simple design and cost-effective manufacturing.
  • High torque transmission capacity, making them suitable for various industrial applications.
  • Zero backlash, ensuring accurate and precise motion transfer.
  • Can accommodate different shaft sizes and materials, providing flexibility in design.

Applications:

Clamp couplings find application in a wide range of industries and mechanical systems, including:

  • Power transmission in industrial machinery and equipment.
  • Robotics and automation systems.
  • Printing and packaging machines.
  • Material handling equipment.
  • Pumps and compressors.
  • Conveyor systems.

Overall, clamp couplings are a reliable and versatile solution for connecting rotating shafts and transferring power in various mechanical setups.
