This paper presents the rationale for the design and development of high horsepower marine planetary gears along with the results of some engineering studies and a progress report covering the development testing of full-scale 40,000- and 60,000-shp marine planetary transmission modules. Recent trends in ship construction, modularization, and introduction of new marine prime movers has given the impetus to the design and development of a family of modular form marine planetary reduction gears. Work completed to date including detail gear designs, transmission hardware trade-off studies, marine architectural installation studies, actual hardware manufacturing and testing, as well as information published in the literature on the use of and the performance of marine planetary gears, shows that the concept of high horsepower marine planetary gears is viable and that substantial benefits will accrue to the owner and the user of this type of equipment. Work described herein related to a joint Curtiss-Wright Power Subsystems/Maritime Administration project on planetary Marine Transmission System Development (Contract Nos. 1-35536 and 3-36247).
