A ship's propulsion arrangement as well as a method for the management of exceptional forces therein

摘要

The present invention relates to a propulsion arrangement including a housing (3) which extends on the outside of a ship and being pivotable in relation thereto, said housing (3) comprising a motor (21) and a propeller (2). The present invention also relates to a method for managing exceptional forces acting on said housing (3). A sliding means including a damping arrangement is arranged on the path (9-10-8) of the power transmission between the ship's hull and the housing (3) of the propulsion arrangement, said sliding means rendering possible an extra relative turning of said propulsion means independent of the forced steering exerted by the main power transmission means (8, 10). On the occurrence of an exceptional force the propulsion arrangement is brought, by said sliding means, to turn in relation to said main power transmission means (8. 10) or to some component thereof.
