#Flexible-Coupling #Geared-Coupling #Fluid-Type-Coupling #Vidhya-Trading-Vadodara A flexible coupling is a type of coupling used to connect two shafts together, while allowing for some degree of angular and/or radial misalignment between them. It is designed to transmit torque and rotational motion between the shafts, while also accommodating any misalignment that may occur due to factors such as thermal expansion, vibration, or manufacturing tolerances. A geared coupling is a type of coupling used to connect two shafts together and transmit torque between them. It consists of two hubs or flanges that are connected by a set of gears, which mesh together to transmit power from one shaft to the other. A fluid coupling is a type of coupling used to transmit torque between two rotating shafts, while also allowing for some degree of misalignment between them. It consists of an impeller or rotor and a turbine or runner, which are enclosed in a sealed housing filled with fluid, typically oil or water.
