MARINE POWER TRANSMISSION Russian patent published in 2014 - IPC B63H23/08 

FIELD: transport.

SUBSTANCE: marine transmission includes angular reduction gears to transfer torque from gas turbine engine to fixed pitch propeller. On the driving shaft of angular reverse reduction gear there are two hydraulically-operated friction clutches. The clutches are symmetrically installed at different sides of angular reverse reduction gear vertical axis with driven half-clutches facing this axis, and their driving half-clutches are rigidly connected with driving shaft of reverse reduction gear. On driven half-clutches, bevel gears are made which gears are facing each other and engaged with bevel wheel installed on output shaft of angular reverse reduction gear. The shaft is connected by clutch with top end of transmission made coaxial with vertical axis of angular reverse reduction gear. Bottom end of vertical transmission is connected by clutch with output shaft of lower angular reduction gear with conical reduction gear.

EFFECT: higher reliability and simpler design of marine power transmission.
