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.
Advantages of Propulsion shafts
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.
