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.

Suitability of Oil Couplings for High-Temperature Environments

Oil couplings are generally suitable for applications involving high-temperature environments, provided certain considerations are taken into account:

  • Oil Selection: Choose an oil with a high temperature resistance and appropriate viscosity for the anticipated operating temperature range.
  • Oil Degradation: High temperatures can accelerate oil degradation, so regular oil analysis and maintenance are essential to monitor and replace degraded oil.
  • Sealing and Contamination: Ensure the coupling is properly sealed to prevent oil leakage and contamination, which can lead to overheating.
  • Material Compatibility: Verify that the materials used in the coupling can withstand the elevated temperatures without compromising structural integrity.
  • Cooling Methods: Consider implementing cooling mechanisms, such as forced air or cooling jackets, to dissipate excess heat.
  • Operating Conditions: Evaluate the duration and frequency of high-temperature operation and factor in any temperature fluctuations.

When appropriately designed, maintained, and monitored, oil couplings can effectively operate in high-temperature environments, providing reliable power transmission and torque conversion.

Industry Standards and Guidelines for Oil Couplings

While there are no specific industry standards or guidelines exclusively dedicated to oil couplings, their design and usage often fall within broader standards related to mechanical power transmission components. Some relevant standards include:

  • ISO Standards: International Organization for Standardization (ISO) standards, such as ISO 9001 for quality management systems and ISO 14691 for industrial fans, provide general guidelines that may apply to oil coupling manufacturers.
  • AGMA Standards: The American Gear Manufacturers Association (AGMA) produces standards related to various types of mechanical power transmission equipment, which could encompass aspects of oil coupling design and manufacturing.
  • API Standards: The American Petroleum Institute (API) develops standards for equipment used in the oil and gas industry, which may include guidelines for components like oil couplings.

Additionally, manufacturers and users of oil couplings should follow best practices, engineering principles, and guidelines for lubrication and maintenance to ensure optimal performance and longevity of the coupling.

Types of Oil Couplings for Specific Uses

Oil couplings come in different variations, each designed to suit specific applications and operating conditions. Some common types include:

  • 1. Constant-Fill Fluid Couplings: These couplings maintain a constant level of fluid, providing consistent torque transmission and smooth operation. They are often used in applications requiring precise control and constant torque delivery.
  • 2. Variable-Fill Fluid Couplings: These couplings allow for variable fluid levels, enabling adjustable torque transmission and speed control. They find applications in situations where speed modulation is essential, such as conveyors and certain industrial processes.
  • 3. Start-Up Fluid Couplings: These specialized couplings provide high torque during startup, helping heavy machinery overcome initial inertia. Once the machinery is up to speed, the coupling allows for smooth and efficient power transmission.
  • 4. Slip Torque Limiters: These couplings are designed to protect equipment from sudden overloads. They slip when the torque exceeds a preset limit, preventing damage to the machinery.
  • 5. Centrifugal Couplings: These couplings use centrifugal force to engage and disengage the transmission of torque based on the rotational speed. They are commonly used in applications like lawn mowers and other small machinery.
  • 6. Fan Fluid Couplings: These couplings are often used in cooling systems for fans and blowers. They allow for variable speed operation and protect the equipment from sudden load changes.
  • 7. Torque Converters: While technically a type of fluid coupling, torque converters are commonly used in automotive applications. They provide variable torque multiplication and enable smooth shifting in automatic transmissions.

The choice of oil coupling type depends on factors such as the desired torque characteristics, speed control requirements, and the specific demands of the application.
