Abstract
In a drive arrangement for a ship, a flexibly mounted drive unit provides the torque for a propeller shaft. The propeller shaft can be supported in a flexibly mounted thrust bearing. A drive shaft interconnecting the drive unit and the propeller shaft includes a single length rigid shaft with a constant velocity universal joint at each end. At least one of the universal joints can absorb axial movement while both can absorb angular movement. The drive unit may consist of a drive motor or the combination of a drive motor and a reduction gear unit interconnected by a rigid shaft with a constant velocity universal joint at each of its ends.
