Abstract
A ship drive system with main engine, main transmission and propeller shaft is supplemented by a transmission branch permitting power transmission in both directions. The branch includes an auxiliary engine, an a.c. generator selectively connected to that auxiliary engine and a controlled transmission unit interposed between the generator shaft and a branch shaft from the main transmission. The unit includes two planetary gear sets of different transmission ratios, their sun gears are mounted on the generator shaft, and a common spider for two sets of planet gears is mounted on the branch shaft; the two internal ring gears for the planetary gears are selectively, one at a time or none, immobilized for power transmission at the respective speed ratio.
