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.

Understanding the Torsional Flexibility of Tyre Couplings and Its Significance

Torsional flexibility is a fundamental characteristic of tyre couplings, and it plays a crucial role in their successful operation in various industrial applications. Torsional flexibility refers to the coupling’s ability to flex and twist along its axis, allowing it to accommodate misalignments and dampen torsional vibrations between the connected shafts.

The significance of torsional flexibility in tyre couplings can be understood through the following points:

• Misalignment Compensation: In real-world applications, it is challenging to achieve perfect alignment between the shafts of connected equipment. Misalignments can occur due to factors such as thermal expansion, manufacturing tolerances, and settling of the machinery. Tyre couplings excel in compensating for these misalignments, both angular and parallel, as they can twist and flex within their rubber tyre element. This capability reduces the forces exerted on the shafts and bearings, minimizing wear and extending the life of the machinery.
• Torsional Vibration Damping: During the operation of rotating equipment, torsional vibrations can be generated due to sudden changes in load or speed. These vibrations can negatively impact the performance of the machinery and cause fatigue failure in critical components. Tyre couplings act as a damping medium, absorbing and dissipating torsional vibrations, resulting in smoother operation and reduced stress on the connected equipment.
• Protection against Shock Loads: In industrial processes, equipment may encounter sudden shock loads due to various factors. Tyre couplings can handle these shock loads by flexing and absorbing the energy generated during the impact. This capability prevents damage to the machinery and safeguards the drivetrain components from sudden stress and failure.
• Reduced Vibrations: Torsional flexibility in tyre couplings significantly reduces vibration transmission between connected shafts. This is especially important in applications where vibrations can negatively affect precision processes or lead to discomfort for operators. By damping these vibrations, tyre couplings contribute to improved productivity and operator comfort.
• Enhanced Equipment Lifespan: The ability to accommodate misalignments and dampen vibrations ultimately leads to reduced wear and tear on machinery components. As a result, equipment using tyre couplings tends to have a longer service life, minimizing downtime and maintenance costs.

In summary, the torsional flexibility of tyre couplings is a critical feature that allows them to compensate for misalignments, dampen torsional vibrations, and protect connected equipment from shock loads. This characteristic significantly contributes to the efficient and reliable operation of industrial machinery, making tyre couplings a popular choice in a wide range of applications.

What is a Tyre Coupling and How Does it Work?

A tyre coupling, also known as a tire coupling, is a type of flexible coupling used to connect two shafts in machinery or equipment. It is designed to transmit torque and accommodate misalignments between the shafts while dampening vibrations and shock loads. The name “tyre coupling” comes from its construction, where a flexible tyre element connects the two hubs of the coupling.

Construction: A tyre coupling typically consists of two metal hubs, each attached to the ends of the shafts to be connected. These hubs are usually made of steel and have a flanged or non-flanged design. The flexible element in the coupling is a tyre made of high-quality rubber or synthetic material. The tyre is placed between the two hubs and secured in place by clamping elements or screws.

Working Principle: The tyre coupling’s working principle involves the transfer of torque from one shaft to the other through the flexible tyre element. When the shafts are misaligned, the tyre can deform and twist slightly, accommodating the angular, axial, and parallel misalignments between the shafts. This flexibility not only reduces stress on the connected machinery but also helps in dampening vibrations and shocks that may arise during the operation.

When torque is applied to one shaft, it causes the tyre to compress on one side and expand on the other, transmitting the torque to the other shaft. The tyre’s flexibility allows it to absorb shocks and vibrations, providing a cushioning effect and protecting the connected equipment from sudden jolts or impact loads.

Advantages of Tyre Couplings:

• Misalignment Tolerance: Tyre couplings can handle both angular and parallel misalignments between the shafts, providing flexibility in installation and reducing the risk of shaft and bearing damage.
• Vibration Damping: The rubber tyre element absorbs vibrations and shocks, leading to smoother operation and extended machinery life.
• Simple Installation: Tyre couplings are relatively easy to install and require minimal maintenance.
• Cost-Effective: They are a cost-effective solution for connecting shafts in various industrial applications.
• Reduced Noise: The flexible tyre element helps in reducing noise levels during operation.

Applications:

Tyre couplings are used in a wide range of industrial applications, including:

• Motor-driven equipment such as pumps, compressors, fans, and blowers.
• Conveyors and material handling systems.
• Power transmission systems in various industries.
• Construction equipment and machinery.
• Marine propulsion systems.
• Steel mills and mining equipment.

Overall, tyre couplings offer a flexible and reliable solution for connecting shafts, ensuring smooth power transmission, and protecting machinery from misalignment-induced stress and vibrations.
