摘要： Die Erfindung betrifft einen Propeller (10) für ein Wasserfahrzeug mit einer Nabe (12) und mindestens zwei Flügeln (14a, 14b, 14c), wobei sich die Flügel (14a, 14b, 14c) ausgehend von der Nabe (12) in radialer Richtung nach außen erstrecken und der Propeller (10) eine gleichmäßige Flügelteilung aufweist, wobei der Winkelabstand zwischen den Flügelspitzen (16a, 16b, 16c) zweier aufeinanderfolgender Flügel (14a, 14b, 14c) des Propellers (10) gegenüber dem Winkelabstand zwischen den Flügelspitzen (16a, 16b, 16c) zweier anderer aufeinanderfolgender Flügel (14a, 14b, 14c) variiert. Die Aufgabe der Erfindung ist es, einen Propeller für ein Wasserfahrzeug zur Verfügung zu stellen, durch den eine unerwünschte Geräuschbildung wirksam reduziert oder vermieden werden kann. Erfindungsgemäß haben die Massenschwerpunkte aller Flügel (14a, 14b, 14c) den gleichen radialen Abstand zu der Nabe (12) und/oder weisen alle Flügel (14a, 14b, 14c) das gleiche Gewicht auf.Erfindungsgemäß haben die Massenschwerpunkte aller Flügel (14a, 14b, 14c) den gleichen radialen Abstand zu der Nabe (12) und/oder weisen alle Flügel (14a, 14b, 14c) das gleiche Gewicht auf.

摘要： A mount for a boat propulsion unit comprises a collar 58 for mounting around an aperture in a boat's hull 56. The collar has an annular groove 60 on an inner surface thereof. A first mating part 64 for mounting an inboard portion 52 of a propulsion unit to the boat, and a second mating part 66, connectable to the first mating part, for mounting an outboard portion 54 of a propulsion unit to the boat, are also provided. The first and second mating parts are connectable through the collar and are configured such that when they are connected they form an external annular recess 74 in an outer surface and an annular gasket 62 is located partly in the groove and partly in the recess to form a seal there-between.

摘要： For damping vibration in, for example, propeller blades or turbine fins, a slug of metal (1) is embraced by two viscoelastic O-rings (5) and forced into a cylindrical cavity (7) formed, e.g. by drilling in a blade (15), the slug being supported by the compression of the O-rings. The compression of the O-rings (5) is chosen, in conjunction with the mass of the slug (1), for resonance in a translational mode at the frequency at which vibrations need to be damped. Resonance at the same frequency in a torsional mode can be achieved by spacing the O-rings apart symmetrically a distance equal to 1/#3 the length of the slug.

摘要： 2122477 9309026 PCTABS00022 A propeller for e.g. a ship has a central hub (34) with a plurality of propeller blades (12). Each blade (12) is composed of a flexible elastomer covering (14) of e.g. rubber which is vulcanized firmly on a core (13). The core (13) and the elastomer covering (14) are moulded and vulcanized to an integral unit which, without expensive after-treatment, forms a propeller having a finished smooth surface and a consistency capable of absorbing and damping the impact and shock pulses from the reaction forces of the water. The elastomer covering is not vulcanized firmly on the entire surface of the core, thereby forming on both sides of the core a compartment (16) which can be filled via a filling valve (18) with a fluid under pressure, e.g. air or water. The elastomer covering is adapted such that when deformed it passively adjusts the pitch of the blade optimally to the instantaneous state of operation. When selectively pumped-up, the propeller can moreover actively be given the geometrical shape best suitable for any purpose.
