Fluid coupling is a hydrodynamic device that uses transmission fluid to transfer rotational motion from one shaft to another. It is used in many industrial applications, marine propulsion systems, and automotive transmission systems.
Fluid Coupling, also known as Hydraulic Coupling, is a hydro-kinetic device used to transmit rotating mechanical power between shafts. It works on the principle of acceleration and deceleration of a hydraulic fluid.
It is a device for transmitting rotation between shafts by means of the acceleration and deceleration of a hydraulic fluid (such as oil). Also known as hydraulic coupling. Structurally, a fluid coupling consists of an impeller on the input or driving shaft and a runner on the output or driven shaft. The two contain the fluid.
