GEARING FOR MODERN MARINE PROPULSION SYSTEMS

The purpose of gearing in marine propulsions is to enable both engine and propeller to function to their best advantage. The application of gearing to steam turbines gas turbines, diesel engines, electric drives and combined power units is considered, along with modern ideas regarding materials, tooth form, gear arrangement, gearcase structure and ancillary equipment. Traditional limitations on the use of nitrided steels are analyzed, and the value of the popular Hertzian shear stress criterion is challenged. The future place of epicyclic gears is discussed with particular reference to diesel drives. The effect of friction forces in tooth-coupling drives is dealt with.
