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.

Compensation for Axial, Angular, and Parallel Misalignments with Flexible Gear Couplings

Flexible gear couplings are known for their ability to accommodate various types of misalignments, including axial, angular, and parallel misalignments. Here’s how they compensate for each type:

• Axial Misalignment: Axial misalignment occurs when the two shafts move closer or farther away from each other along the axis of rotation. Flexible gear couplings can absorb this type of misalignment through their flexible design, allowing the gear teeth to articulate and adjust to the axial movement without transmitting harmful forces to the connected equipment.
• Angular Misalignment: Angular misalignment occurs when the two shafts are not collinear and form an angle with each other. Flexible gear couplings can accommodate angular misalignment by allowing the gear teeth to articulate and flex as the shafts are angularly displaced. This flexibility ensures that torque transmission remains smooth and minimizes stress on the coupling and connected equipment.
• Parallel Misalignment: Parallel misalignment happens when the two shafts are offset horizontally while maintaining parallelism. Flexible gear couplings can handle this misalignment by utilizing their flexible elements to adjust to the lateral displacement of the shafts. The ability to compensate for parallel misalignment prevents excessive forces from being transmitted to the machinery, protecting it from damage.

Thanks to their design and material properties, flexible gear couplings provide a reliable solution for compensating for axial, angular, and parallel misalignments, making them suitable for a wide range of applications in various industries.

Design Considerations for Selecting a Flexible Gear Coupling

When selecting a flexible gear coupling for a specific application, several design considerations are crucial to ensure optimal performance and reliability:

• Torque Capacity: Determine the maximum torque requirement of the application and choose a coupling with sufficient torque capacity to handle the transmitted loads without exceeding its limits.
• Speed: Consider the operating speed of the machinery and select a coupling that can handle the rotational speed without generating excessive heat or vibrations.
• Misalignment Tolerance: Assess the expected misalignment between the shafts in the system and choose a coupling that can accommodate both angular and parallel misalignments within acceptable limits.
• Service Environment: Evaluate the working conditions, including temperature, humidity, and the presence of corrosive agents, and select a coupling made from materials suitable for the specific environment.
• Space Limitations: Take into account the available space for the coupling installation and choose a compact design that fits within the available constraints.
• Alignment Maintenance: Consider the ease of alignment and maintenance requirements of the selected coupling. Some couplings may require more frequent maintenance than others.
• Backlash: Evaluate the application’s tolerance for backlash (angular play) in the coupling and select a design that meets the required precision.
• Torsional Stiffness: Determine the need for torsional stiffness in the system to avoid torsional vibrations and ensure accurate torque transmission.
• Resonance Avoidance: Identify potential resonance frequencies in the system and choose a coupling that helps avoid resonance, preventing amplified vibrations.
• Cost: Consider the budget constraints and compare the cost-effectiveness of different coupling options while ensuring the selected coupling meets all the necessary requirements.

By carefully considering these design factors, engineers and designers can choose the most suitable flexible gear coupling for their specific application, ensuring smooth operation, reduced maintenance, and extended equipment lifespan.

Advantages of Flexible Gear Couplings

Flexible gear couplings offer several advantages over other types of couplings:

1. Misalignment Compensation: Flexible gear couplings can accommodate angular, parallel, and axial misalignments between the connected shafts. This ability to compensate for misalignment reduces stress on the machinery, shafts, and bearings, leading to improved overall system reliability and reduced maintenance requirements.
2. Vibration Damping: The elastomeric flexible element in the coupling acts as a damping mechanism, absorbing vibrations and shocks during operation. This feature helps in reducing noise levels and protecting the connected equipment from damage caused by excessive vibrations.
3. High Torque Transmission: Flexible gear couplings are designed to handle high torque loads, making them suitable for heavy-duty applications in various industries.
4. Compact Design: Compared to some other types of couplings, flexible gear couplings have a relatively compact design, making them suitable for applications with space constraints.
5. Easy Installation and Maintenance: The simple design and flexible nature of these couplings make them easy to install and maintain, minimizing downtime and associated costs.
6. Reliability: Flexible gear couplings are known for their reliability and long service life, ensuring uninterrupted power transmission in critical industrial processes.
7. Torsional Flexibility: The elastomeric material used in the coupling provides high torsional flexibility, enabling smooth torque transmission even in applications with varying loads and speeds.

Overall, the advantages of flexible gear couplings make them a popular choice for power transmission systems in various industries, including mining, steel, paper, and chemical processing, where the demands for performance, reliability, and durability are essential.
