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 to Install and Align a Universal Coupling in a Mechanical Assembly
Proper installation and alignment of a universal coupling are crucial for its efficient and reliable operation. Here are the steps to install and align a universal coupling in a mechanical assembly:
- Prepare the Coupling Components: Ensure that all the universal coupling components are clean and free from any dirt, debris, or damage. Verify that the shafts to be connected are appropriately sized and compatible with the coupling.
- Inspect the Coupling: Check the universal coupling’s spider or cross assembly for any signs of wear, cracks, or damage. Replace the spider if it shows any signs of deterioration.
- Align the Shafts: Position the two shafts that need to be connected to the universal coupling. Align the shafts as closely as possible, aiming for minimum misalignment. Ensure that the shafts are parallel and that the angular misalignment is within the coupling’s specified tolerance.
- Insert the Spider: Carefully insert the spider or cross assembly into the forks of the universal coupling. Make sure the spider is properly seated and fits securely in both forks.
- Secure the Coupling: Depending on the type of universal coupling, secure the forks onto the shafts using set screws, bolts, or clamps. Follow the manufacturer’s guidelines for the specific coupling model.
- Check for Free Movement: After securing the coupling, check that the spider allows for free movement of the shafts within the specified angular and axial limits. The shafts should rotate smoothly without any binding or interference.
- Perform a Trial Run: Before finalizing the installation, perform a trial run to ensure that the coupling operates smoothly and without any unusual vibrations or noises.
- Make Final Adjustments: If necessary, make minor adjustments to the alignment or coupling position to optimize the performance. Recheck the shaft alignment and ensure that it meets the required specifications.
- Tighten Fasteners: Once the alignment is satisfactory, tighten all the fasteners securely to prevent any movement or slippage during operation.
- Perform Regular Maintenance: Schedule regular inspections and maintenance for the universal coupling to ensure its continued performance and reliability. Lubricate the coupling as per the manufacturer’s recommendations to reduce wear and friction.
Remember that accurate alignment of the universal coupling will minimize stress on the shafts and extend the lifespan of the coupling and connected components. If you are unsure about the installation process or the coupling’s compatibility with your system, consult the manufacturer or a qualified engineer for guidance.
Can a Universal Coupling Reduce Vibration and Noise in Mechanical Systems?
Yes, a universal coupling can help reduce vibration and noise in mechanical systems, especially in applications where misalignment is a concern. Universal couplings are designed to accommodate angular misalignment between shafts, which can arise due to various factors such as manufacturing tolerances, thermal expansion, or dynamic forces.
When shaft misalignment occurs in a mechanical system, it can lead to vibration and noise during operation. This is because misaligned shafts cause uneven distribution of forces and result in increased stresses on bearings, shafts, and other connected components. The resulting vibration and noise can be detrimental to the performance, efficiency, and lifespan of the machinery.
By using a universal coupling, the coupling’s design allows it to compensate for angular misalignment and minimize the transmission of misalignment-induced vibrations to the connected equipment. The flexibility of the universal coupling allows it to handle moderate angular misalignments while transmitting torque smoothly between shafts. This reduces the stresses on the connected components and mitigates the vibration and noise levels.
However, it is important to note that while universal couplings can help reduce vibration and noise caused by angular misalignment, they may not address other sources of vibration and noise in the system. For example, if the vibration is primarily caused by unbalanced rotating parts, worn bearings, or other factors unrelated to misalignment, a universal coupling alone may not be sufficient to eliminate the issue.
Overall, when selecting a universal coupling for a specific application, it is essential to consider the level of misalignment it can handle, the type of vibration and noise issues present, and whether additional measures are required to address other sources of vibration and noise in the mechanical system.
Can Universal Couplings Accommodate Misalignment in Shafts and Drives?
Yes, universal couplings are specifically designed to accommodate misalignment between shafts and drives. The unique design of universal couplings allows them to transmit torque and rotation between two shafts that are not in perfect alignment with each other. There are two primary types of misalignment that universal couplings can handle:
- Angular Misalignment: Universal couplings can handle angular misalignment, which occurs when the shafts are not in line with each other and form an angle. The design of the universal joint allows it to bend and flex at different angles, allowing the shafts to stay connected and transmit torque even when they are not perfectly aligned.
- Parallel Misalignment: Universal couplings can also handle parallel misalignment, which occurs when the two shafts are not perfectly parallel to each other. The flexible nature of the universal joint allows it to compensate for small variations in parallel alignment, ensuring that the shafts remain connected and transmit power efficiently.
By accommodating misalignment, universal couplings help to reduce stress on the shafts and other connected components, thus preventing premature wear and failure. They are commonly used in various applications, including automotive drivetrains, industrial machinery, marine propulsion systems, and aerospace equipment, where misalignment is inevitable due to the dynamic nature of the systems.
