Hydraulic couplings

Hydraulic couplings are devices designed to transmit torque between rotating shafts by means of a working medium (liquid), without a rigid mechanical connection. In operating systems they allow smooth transmission of power between the torque source and the driven mechanism.

Typical features of hydraulic couplings include torque transmission via a liquid, the possibility of partial slip between input and output, and design adaptation for various operating conditions. In practice they are used in industrial drives and machinery applications where a stepless connection of torque is required.

Specific design solutions and operating parameters vary according to the intended use of the given coupling; detailed technical data are provided with individual products and technical documentation. This description generally applies to the category of hydraulic couplings as technical components.
