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.

fluid drive coupling

What are the different fluid media used in fluid drive couplings, such as oil or water?

Fluid drive couplings can use various types of hydraulic fluids as the medium to transmit torque between the driving and driven elements. The choice of fluid media depends on the specific application requirements and the operating conditions. Some common fluid media used in fluid drive couplings include:

  • Oil: Mineral oil, synthetic oil, or a blend of various oils are commonly used as hydraulic fluids in fluid drive couplings. These oils offer good lubrication properties and thermal stability, making them suitable for various industrial applications. Oil-based fluid drive couplings are often preferred for heavy-duty and high-temperature applications.
  • Water-Glycol: Water-glycol mixtures are widely used as hydraulic fluids in fluid drive couplings that require fire-resistant properties. These fluids are commonly used in industries where fire hazards are a concern, such as steel mills and foundries.
  • Water-Oil Emulsions: Emulsions of water and oil are used in certain fluid drive couplings, especially in applications where fire resistance and cooling properties are essential. Water-oil emulsions provide both good lubrication and effective heat dissipation capabilities.
  • Water: In some specific applications, plain water is used as the hydraulic fluid in fluid drive couplings. Water offers excellent cooling properties and is suitable for applications where there is no risk of freezing or where fire resistance is not a primary concern.
  • Biodegradable Fluids: Biodegradable hydraulic fluids, such as vegetable-based oils or synthetic esters, are employed in environmentally sensitive applications. These fluids are biodegradable and offer good lubrication properties while minimizing environmental impact.
  • Specialty Fluids: Depending on the specific requirements of niche applications, other specialty hydraulic fluids with unique properties may be used in fluid drive couplings. These specialty fluids are tailored to meet specific demands, such as extreme temperatures or aggressive operating environments.

The selection of the appropriate hydraulic fluid for a fluid drive coupling depends on factors like the operating temperature, load conditions, environmental considerations, and compatibility with the coupling’s materials. Manufacturers usually provide guidelines on the suitable fluid types and specifications for their specific fluid drive coupling models.

Regular monitoring and maintenance of the hydraulic fluid are essential to ensure optimal performance and to extend the service life of the fluid drive coupling. Fluid condition monitoring helps identify any signs of contamination or degradation, enabling timely fluid replacement or treatment as necessary.

It is crucial to follow the manufacturer’s recommendations regarding fluid type, fluid level, and fluid change intervals to ensure the fluid drive coupling operates efficiently and reliably in its intended application.

Can fluid drive couplings be used in applications requiring continuous variable speed control?

Yes, fluid drive couplings can be used in applications requiring continuous variable speed control. The unique design and operating principle of fluid drive couplings allow them to provide smooth and precise speed regulation over a wide range of operating speeds.

Fluid drive couplings utilize a hydrodynamic torque transmission mechanism, where the amount of torque transmitted between the driving and driven elements is determined by the amount of fluid present in the coupling’s working chamber. By adjusting the fluid level, the coupling’s output speed can be continuously varied.

The fluid level in the coupling can be controlled manually, automatically, or electronically, depending on the specific application requirements. Here are some methods used to achieve continuous variable speed control with fluid drive couplings:

  • Manual Adjustment: In some applications, the fluid level in the coupling can be adjusted manually by operators. By changing the fluid level, the speed of the driven element can be continuously controlled, providing versatility in the system’s operation.
  • Hydraulic Control: Certain fluid drive couplings incorporate hydraulic control systems to adjust the fluid level automatically. These control systems respond to changes in the driving element’s speed or load and modulate the fluid level to maintain the desired speed at the driven element.
  • Electrical Control: Advanced fluid drive couplings can be equipped with electrical control systems that use sensors and feedback loops to precisely regulate the fluid level. This enables accurate and automated speed control based on the system’s requirements.

Continuous variable speed control offered by fluid drive couplings is advantageous in various applications, including conveyor systems, industrial mixers, pump drives, and certain types of marine propulsion. The ability to smoothly adjust the speed helps optimize energy consumption, reduce wear and tear on equipment, and enhance overall process efficiency.

Additionally, fluid drive couplings provide overload protection, which is crucial in applications requiring variable speed control. When the system experiences sudden load fluctuations or overloads, the fluid drive coupling can slip to protect the connected machinery from damage.

It is important to select the appropriate fluid drive coupling model with the required variable speed control capabilities based on the specific application’s speed range, torque demands, and control requirements. Working closely with the coupling manufacturer and understanding the system’s operating conditions will ensure the optimal coupling is chosen to achieve smooth and efficient variable speed control.

fluid drive coupling

What is a fluid drive coupling, and how does it function in mechanical power transmission?

A fluid drive coupling, also known as a hydraulic coupling, is a mechanical device used to transmit power between two shafts in a machinery system. It operates on the principle of hydrodynamic power transmission, utilizing hydraulic fluid to transfer torque and rotational motion from the driving shaft to the driven shaft.

The basic construction of a fluid drive coupling consists of two primary components: a driving impeller (pump) and a driven impeller (turbine), both housed within a sealed casing. The casing is filled with hydraulic fluid, typically oil. When the driving impeller is activated, it starts rotating, creating a flow of hydraulic fluid within the casing. This fluid movement generates a hydraulic force that drives the driven impeller to rotate at the same speed as the driving impeller.

The key features of how a fluid drive coupling functions in mechanical power transmission are as follows:

  • No Mechanical Contact: Fluid drive couplings are non-contact power transmission devices. There is no direct mechanical connection between the driving and driven shafts. Instead, they rely on the hydraulic fluid to transfer power.
  • Torque Amplification: Fluid drive couplings can provide torque amplification during startup or when the driven shaft experiences resistance. As the driving impeller starts rotating, the hydraulic fluid movement gradually accelerates the driven impeller, effectively increasing the torque applied to the driven shaft.
  • Smooth Operation: Due to the hydrodynamic nature of power transmission, fluid drive couplings offer smooth and gradual acceleration, reducing shock loads on the machinery and minimizing wear on mechanical components.
  • Slip Control: In certain applications, fluid drive couplings allow controlled slippage between the driving and driven shafts. This feature can protect the machinery from sudden overloads and act as a safety mechanism during transient operations.
  • Speed Regulation: Fluid drive couplings can regulate the speed of the driven shaft by adjusting the input speed of the driving shaft. This speed regulation can be useful in applications where precise control of output speed is required.
  • Overload Protection: In cases of excessive load or torque, fluid drive couplings can slip, absorbing the excess energy and protecting the machinery from damage.

Fluid drive couplings find applications in various industries, including automotive, industrial machinery, mining, and marine. They are commonly used in applications where smooth power transmission, torque amplification, and overload protection are crucial.

It’s essential to consider the specific requirements of the machinery system and the torque and speed characteristics when selecting a fluid drive coupling. Proper maintenance and monitoring of hydraulic fluid levels and condition are necessary to ensure optimal performance and longevity of the fluid drive coupling in mechanical power transmission.
