The outstanding features of a marine high-capacity gear transmission device are high speed, heavy load and low noise. Through a description of the main types of marine gear transmission units and an analysis of their uses it can be shown that the technology of marine gear transmission devices are developing in the direction of attaining high-load capacity, high reliability, low noise, variegated transmission forms and miniaturization. After a discussion of the hot-spot problems of gear design technology both at home and abroad the authors expound some key issues concerning marine gear technology in China. They include the design technology of multi-engine, multi-shaft combined crossover transmission units and high-power density ones, comprehensive control techniques for vibration and noise reduction and the dynamic design of innovative transmission elements and components.
