Rotating mechanical power can be transmitted by a device called fluid coupling. Also known as hydraulic coupling, this device is comprised of housing, impeller and turbine. Industries with applications involving rotational power uses this device. The industries that use it are automotive, railway and aviation. The fluid in this device absorbs misalignment of drive shaft and driven shaft. Transmission fluid is accelerated or decelerated for transferring power from one shaft to another. Fluid coupling is essential in industrial applications for protecting overloading, vibration free & noiseless power transmission. In whichever condition it is used, it ensures smooth power transmission. The fluid in this device is decided based on factors, like density, viscosity and flash points.

Fluid Coupling FAQ:
Q: What is a fluid coupling?
A: A fluid coupling is a device used for transmitting torque and providing a smooth start up in mechanical power transmission systems. It consists of an output shaft, an input shaft, and a fluid filled chamber that connects the two shafts.
Q: How does a fluid coupling work?
A: A fluid coupling works based on the principle of hydro- kinetic and requires that the output speed be less than the input. The power is transmitted from one shaft to another shaft by means of acceleration and deceleration of a hydraulic fluid.
Q: What are the advantages of using a fluid coupling?
A: Fluid couplings offer several advantages, like:
No Wear
High Torque Transmission
Easy to Use
Less Complex Design
Easy Installation and Integration
Overload Protection
Q: Where are fluid couplings used?
A: Fluid couplings are used in automotive transmission system, marine propulsion system and in industries for power transmission. Other areas of application include:
Belt Conveyors
Crushers and Mills
Marine Propulsion
Mining Equipment
Power Generation
Metal Processing
Construction Machinery
Q: Can fluid couplings be controlled or adjusted?
A: Yes, fluid couplings can be controlled or adjusted to some extent. The couplings can be adjusted on controlled in various ways such as fill level adjustment, external control devices, and fluid viscosity and temperature. It helps in altering the torque transmission characteristics. Some couplings may have external controls to vary the amount of slippage or adjust the speed torque characteristics.
Q: Is maintenance required for fluid couplings?
A: Fluid couplings generally require minimal maintenance. Periodic inspection of the fluid level, fluid condition, and alignment of the coupling is required. If the fluid shows signs of degradation or contamination, it may need to be replaced.
