Propulsion Parts

Propulsion Shafts

A ship’s propeller shaft transmits mechanical energy from the main engine to the propeller. When there is more than one transmission element, the propeller shaft is a kind of shafting line. Applications. The main function of the propeller shaft is to turn the propeller.

Mechanical Couplings

Couplings are mechanical components used to connect two in-line shafts to enable one shaft to drive another at the same speed. A coupling can be rigid or flexible, allowing the various amounts of angular, radial, and axial misalignment between the two shafts.

Hydraulic Sleeve Couplings

An Introduction to the Sleeve Couplings, Their Parts & Materials. Couplings are used to connect two shafts for torque transmission in varied applications. Coupling may be rigid or they may provide flexibility and compensate for misalignment. They may also reduce shock loading and vibration.
