- Abstract
The use of the marine gearbox is very important in most propulsion systems based on gas turbines, due to the high value of the turbine speed - propeller shaft ratio. Particular ships' characteristics differ from the civilian ships with several features which gives them the ability to navigate for a long time under different conditions. As a result of this navigating conditions, the main gearing inside the gearbox will find itself under different stages of structural stress. The stages will be analyzed by using the finite element analysis. The stress degree can be minimized by carefully choosing the correct type of material for the gearing, which is in close connection with the amount of heat that is dissipated due to meshing under different conditions. The purpose of this paper is the optimization of the gearing inside the gearbox such it can suffer as small as possible structural deformations under the factors determined by the use of the gearbox under different working conditions.
