Abstract
The usage of modern thrusters allows to combine the functions of the drive and the
ship rudder in one assembly, which are separated in conventional ship propulsions. The
horizontally oriented propeller is supported in a vertically rotatable nacelle, which is mounted
underneath the ship hull. The propeller can be directly or indirectly driven by an electric motor
or combustion engine. The direct drive requires the installation of a low speed electric motor in
the nacelle. The present paper concentrates on indirect drives where the driving torque
is transferred by bevel gear stages and shafts from the ship to the propeller. Due to the closed
and inaccessible construction high demands on the reliability have to be achieved. Especially for
the design of the highly loaded bevel gear stage accurate information to the occurring loads are
required. The experience of operating thrusters show that primarily rarely occurring special load
cases have to be considered, which can only be determined by long-term measurements at very high
cost. By means of a detailed multibody system simulation model of the thruster it is already
possible to develop a basic knowledge to the dynamic properties of the drive train and
to determine design loads for drivetrain components.
