Ship's drive system for safe, effective, adaptable operation has mutually engaging spur wheels, hydrodynamic coupling mounted on faster rotating shaft, mutually engaging gear wheels

摘要

The system has mutually engaging spur wheels (3) for stepping up the revolution rate of the drive engine (1) and shaft (2) and a hydrodynamic coupling (5) mounted on the rapidly rotating shaft (4) to further transfer the drive power via a second rapidly rotating shaft (6), from which the revolution rate of the shaft (8) driving the propeller (9) is reduced by two or more mutually engaging gear wheels (7).
