<p>A marine gear drive has two drivepinions for coupling to respective high-speed and low-speed engines and both pinions connected through intermediate gears to a common larger gear adapted to be coupled to a propeller shaft. The drive pinions, intermediate gears and larger gear are disposed in only two planes and one drive pinion is in the driving train from the other drive pinion to the larger gear. An arrangement for a twin propeller drive with each propeller driven by high-speed and low-speed engines as aforesaid, counter-rotates the propellers without reversing the direction of rotation of the drive inputs. 1.</p> |
