Fluid Couplings Overview

A fluid coupling, or a hydraulic coupling, is a hydrodynamic device that transmits rotating mechanical energy between two axes, or drive shafts. They’re used to gently accelerate belt drives.

Fluid couplings:

• Limit torque
• Provide load sharing upon start-up, allowing for a soft start
• Dampen torsional vibrations

Couplings increase your conveyor system’s overall productivity and longevity. Maximum energy savings is also achieved when fluid couplings are used, due to current peak reduction.

In today’s industry, fluid couplings are mostly used in heavy industry and marine applications, although fluid couplings were also used in automotive transmissions and electric motors until the late 1940s.

The primary advantage of a fluid coupling is that it allows the operator to change the speed of the power transmission without shock loading it. Couplings can provide overload protection to power transmissions.
