Problems solved by technology

[0005] However, if the sail rotor is too large in the axial direction to be ideally based on a rigid body, simple balancing is no longer sufficient to achieve a stable turning motion without unbalance

Embodiment Construction

[0039] figure 1 A preferred Magnus rotor 1 is shown, which has a rotating body 2 with a cylindrical shape.

[0040] according to figure 1 , the Magnus rotor 1 has a rotating body 2 ready to rotate and rotationally symmetrical about the axis of rotation, which is supported by a carrier body 3 . The rotating body 2 is a cylindrical hollow body which lies vertically on a plane 9 which is part of the ship and is referred to below as the ship plane. Ribs 6 are shown on the inner side of the rotating body 2 , which serve as stiffening means for stiffening the rotating body 2 . The ribs extend in the circumferential direction of the rotating body 2 . Additionally, ribs 6 serve to accommodate counterweights. For this purpose, the ribs 6 are provided with recesses, holes and / or protrusions at regular intervals in the circumferential direction. For example screws can be used to connect the balancing weight to the ribs 6 . The ribs 6 extend over the entire circumference at a define...

Abstract

The invention relates to a Magnus rotor comprising a cylindrical body of revolution for converting wind power into a feed force using the Magnus effect. The Magnus rotor comprises: a rotational shaft about which the body of revolution rotates; a support member on which the body of revolution is mounted; and a body of revolution which has means for the reinforcement thereof. The body of revolution is primed in at least two planes arranged at a mutual spacing in the axial direction perpendicular to the rotational shaft of the body of revolution in order to accommodate balancing weights. The invention further relates to a method for balancing a body of revolution according to the invention, said body being rotated by means of a drive motor inside the Magnus rotor, imbalances of a body of revolution of the Magnus rotor in at least two axially offset planes perpendicular to the rotational shaft of the body of revolution being detected, and corresponding balancing weights being attached to reinforcing means in the respective planes.

Description

technical field [0001] The invention relates to a Magnus rotor with a rotating body for converting wind power into propulsion using the Magnus effect, and a method for balancing the rotating body. Background technique [0002] A Magnus rotor, also known as a Fleitner rotor or a sail rotor, or a similar rotationally symmetric rotating body that rotates about an axis of rotation and thereby utilizes the Magnus effect to transform the air flow, and in particular the wind, almost transverse to the air The force of the flow, which can be used as a propulsion force. [0003] During the rotational movement of a Magnus rotor, in particular a large Magnus rotor, imbalances can arise due to an asymmetric mass distribution. Vibrations occur due to the unbalance, which can interfere with the smooth running of the Magnus rotor and lead to increased wear of the bearing or even to destruction. [0004] In particular rigid rotating bodies with a rigid axis of rotation, that is to say in t...
