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.

Cost Implications of Using Fluid Couplings in Comparison to Other Power Transmission Methods
The cost implications of using fluid couplings in power transmission depend on various factors, including the application requirements, the size of the system, and the operational conditions. While fluid couplings offer several advantages, they may have different cost considerations compared to other power transmission methods like mechanical clutches, VFDs (Variable Frequency Drives), and direct mechanical drives.
1. Initial Investment:
The initial cost of a fluid coupling can be higher than that of a mechanical clutch or a direct mechanical drive. Fluid couplings contain precision components, including the impeller and turbine, which can impact their initial purchase price.
2. Maintenance Costs:
Fluid couplings are generally considered to have lower maintenance costs compared to mechanical clutches. Mechanical clutches have wear and tear components that may require more frequent replacements, leading to higher maintenance expenses over time.
3. Energy Efficiency:
Fluid couplings are highly efficient in power transmission, especially during soft-start applications. Their ability to reduce shock loads and provide a smooth acceleration can result in energy savings and operational cost reductions.
4. Space and Weight:
Fluid couplings are usually more compact and lighter than some mechanical clutches, which can be advantageous in applications with space constraints or weight limitations.
5. Specific Application Considerations:
The suitability and cost-effectiveness of fluid couplings versus other power transmission methods can vary based on specific application requirements. For example, in soft-start applications, fluid couplings may be the preferred choice due to their ability to reduce mechanical stress and protect connected equipment.
6. Lifespan and Reliability:
While the initial cost of a fluid coupling might be higher, their longevity and reliability can lead to lower overall life cycle costs compared to other power transmission methods.
In conclusion, the cost implications of using fluid couplings in power transmission depend on the particular application and the total cost of ownership over the equipment’s lifespan. Although fluid couplings may have a higher initial investment, their long-term reliability, energy efficiency, and lower maintenance costs can make them a cost-effective choice in many industrial applications.
Use of Fluid Couplings in Horizontal and Vertical Shaft Arrangements
Yes, fluid couplings can be used in both horizontal and vertical shaft arrangements, providing flexible power transmission solutions for various industrial applications.
1. Horizontal Shaft Arrangements:
In horizontal shaft arrangements, the fluid coupling is installed between the driving and driven shafts, which are positioned horizontally and parallel to each other. The fluid coupling allows torque to be transmitted smoothly from the driving shaft to the driven shaft, enabling the machinery or equipment to start up gradually without abrupt shocks or overloading. This feature is especially beneficial in applications where heavy loads need to be accelerated smoothly, such as conveyors, crushers, and pumps.
2. Vertical Shaft Arrangements:
In vertical shaft arrangements, the fluid coupling is used to connect the driving and driven shafts, which are positioned vertically and aligned on top of each other. The fluid coupling allows for torque transmission and controlled acceleration, just like in horizontal arrangements. Vertical shaft fluid couplings are commonly used in applications such as vertical conveyors, hoists, and elevators, where they provide smooth starting and stopping of the equipment, preventing sudden jolts and reducing stress on the machinery.
Fluid couplings offer versatility in power transmission and are adaptable to various shaft arrangements, making them suitable for a wide range of industrial setups. Whether the application involves horizontal or vertical shafts, fluid couplings play a crucial role in enhancing the performance, safety, and efficiency of power transmission systems.
