Hydraulic couplings are one of three types of couplings when divided by function, including:

– Shaft coupling: This type is used to permanently connect shafts, only when the machine stops and the shaft is disconnected will the shafts separate. This shaft coupling has types such as: tight shaft coupling, elastic shaft coupling, compensating shaft coupling, etc.

– Clutch: This is a coupling with a structure also known as a hydraulic coupling or a torque converter. They are used to connect or separate shafts with other rotating machine parts at any time. Clutches usually have the following types: friction clutch, engagement clutch, electromagnetic clutch, etc.

– Automatic clutch: This is a type of coupling that can automatically connect or separate shafts with many different rotating machine parts. Automatic clutches have the following types: safety clutch, centrifugal clutch, one-way clutch, etc.
