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.

How does a flexible coupling handle torsional vibrations in rotating machinery?

A flexible coupling is designed to handle torsional vibrations in rotating machinery by providing a degree of flexibility and damping. Torsional vibrations are oscillations that occur in the drivetrain due to torque variations, sudden load changes, or other transient events. These vibrations can lead to resonance, excessive stress, and premature failure of components.

Flexible couplings mitigate torsional vibrations through the following mechanisms:

• Torsional Compliance: Flexible couplings have an element, such as an elastomeric insert, that can deform or twist to absorb torsional shocks. When the drivetrain experiences torsional vibrations, the flexible element flexes, effectively isolating and dampening the vibrations before they propagate further.
• Damping: Many flexible couplings have inherent damping properties, especially those with elastomeric components. Damping dissipates the energy of the torsional vibrations, reducing their amplitude and preventing resonance from occurring.
• Tuned Design: Some flexible couplings are specifically designed with specific torsional characteristics to match the drivetrain’s requirements. By tuning the coupling’s stiffness and damping properties, engineers can ensure optimal torsional vibration control.
• Torsional Stiffness: While flexible couplings provide flexibility to absorb vibrations, they also offer a degree of torsional stiffness to maintain the torque transmission efficiency between the shafts.

It is important to select the appropriate flexible coupling based on the specific torsional characteristics and requirements of the rotating machinery. Different applications may demand different types of couplings with varying levels of flexibility and damping. High-performance flexible couplings can effectively minimize torsional vibrations, protecting the drivetrain and connected equipment from excessive stress and potential damage.

Additionally, proper alignment of the flexible coupling during installation is crucial to ensure its optimal performance in mitigating torsional vibrations. Misalignment can introduce additional stresses and exacerbate torsional issues in the system. Regular inspection and maintenance of the flexible coupling will help identify any signs of wear or damage that may affect its ability to handle torsional vibrations effectively.

Can flexible couplings be used in both horizontal and vertical shaft arrangements?

Yes, flexible couplings can be used in both horizontal and vertical shaft arrangements. The design of flexible couplings allows them to accommodate misalignment and compensate for angular, parallel, and axial displacements between the shafts, making them suitable for various shaft orientations.

Horizontal Shaft Arrangements:

In horizontal shaft arrangements, where the shafts are parallel to the ground or horizontal plane, flexible couplings are commonly used to connect two rotating shafts. These couplings help transmit torque from one shaft to another while accommodating any misalignment that may occur during operation. Horizontal shaft arrangements are common in applications such as pumps, compressors, conveyors, and industrial machinery.

Vertical Shaft Arrangements:

In vertical shaft arrangements, where the shafts are perpendicular to the ground or vertical plane, flexible couplings are also applicable. Vertical shafts often require couplings that can handle the additional weight and forces resulting from gravity. Flexible couplings designed for vertical applications can support the weight of the rotating equipment while allowing for some axial movement to accommodate thermal expansion or other displacements. Vertical shaft arrangements are commonly found in applications such as pumps, gearboxes, turbines, and some marine propulsion systems.

Considerations for Vertical Shaft Arrangements:

When using flexible couplings in vertical shaft arrangements, there are a few additional considerations to keep in mind:

• Thrust Load: Vertical shafts can generate thrust loads, especially in upward or downward direction. The flexible coupling should be selected based on its capacity to handle both radial and axial loads to accommodate these forces.
• Lubrication: Some vertical couplings may require additional lubrication to ensure smooth operation and reduce wear, particularly if they are exposed to high axial loads or extended vertical shafts.
• Support and Bearing: Proper support and bearing arrangements for the vertical shaft are essential to prevent excessive shaft deflection and ensure the flexible coupling functions correctly.

Overall, flexible couplings are versatile and adaptable to various shaft orientations, providing efficient power transmission and misalignment compensation. Whether in horizontal or vertical arrangements, using the appropriate flexible coupling design and considering the specific application requirements will help ensure reliable and efficient operation.
