Product Description
Fluid Coupling Chain Jaw Flexible Flange Gear Rigid Spacer Motor Shaft Universal Half Reducer Spline Stainless Steel Elastomeric coupling
A fluid coupling is a torque converter used in mechanical power transmission systems to transmit torque from 1 rotating shaft to another. It consists of 2 halves, the impeller, and the runner, which are placed in a housing filled with a hydraulic fluid such as oil or water.
When one-half of the fluid coupling is rotated, it creates a fluid flow within the housing, which in turn causes the other half to rotate. The fluid coupling uses fluid dynamics principles to transmit torque between the 2 halves, with the amount of torque being proportional to the speed difference between the 2 shafts.
One of the key advantages of a fluid coupling is its ability to provide a smooth and gradual torque transfer between the 2 shafts, without any mechanical connection. This can help to reduce wear and tear on the equipment and improve overall system efficiency.
Fluid couplings are commonly used in various industrial applications, including mining, construction, and marine equipment. They are also used in automotive transmissions, where they can help provide a smooth and efficient torque transfer between the engine and the wheels.
Overall, a fluid coupling provides a reliable and efficient way to transmit torque between 2 rotating shafts, without any mechanical connection. With their ability to provide a smooth and gradual torque transfer, they are a popular choice for a wide range of industrial and automotive applications.
