Fluid Drives and Fluid Couplings

Fluid drives and fluid couplings are hydrodynamic devices that transmits rotational power. There are 4 main components of a fluid coupling: The housing, the input element (including the impeller), the output element (including the runner) and the oil. The housing contains the oil and the rotating mechanical components. The input element connects to the driving equipment like a motor or a turbine. Inside the coupling or fluid drive is an impeller. The impeller drives. The output element connects to the driven equipment such as a pump or fan. Inside the coupling is a runner. Between the input and output elements is oil. Kinetic energy is added to the oil when input element rotates. This energy is smoothly transferred to the output element and the driven equipment.

Hydrodynamic Journal Bearings

 What type of bearings does TRI work on?

Bearings are used to reduce the friction in moving components. There are linear bearings, journal bearing and thrust bearings. A journal is the part of the shaft that turns inside the bearing. A journal bearing supports a shaft so that it may rotate freely. A thrust bearing is used to resist the axial movement of the shaft.
