A fluid coupling is a mechanical mechanism that allows rotational power to be transferred from one shaft to another. A fluid coupling is made of a driving impeller, also known as a pump, that connects to the input shaft to produce rotation moment and kinetic energy. A powered impeller, referred to as a turbine, is attached to the output shaft and aids in the transmission of the rotational moment by centrifugal force delivered to the turbine.
The key components of Fluid Coupling are as follows:
Shell: This is the outside portion of the fluid coupling; it prevents fuel, impeller, and turbine leaks. A shell is a strong metal casing that functions as an airtight seal.
Pump or Impeller: This is a centrifugal pump that used to be connected to the driveshaft and created kinetic energy that was then transferred to the fluid within.
Fluid: This form of connection should have a thin fluid. The fluid's job is to transform kinetic energy into centrifugal force, which it then transfers to the turbine.
Turbine: The fluid coupling has a turbine that detects the centrifugal force and generates a rotating moment. The turbine shaft is connected to the output shaft, which transfers the rotational moment.
