Abstract
Official abstract text for this publication.
A method for changing slide bearing pads arranged on a rotor shaft of a rotor bearing arrangement of a wind turbine, includes the method steps: moving the slide bearing pad to be changed to a removal opening by rotating the rotor shaft; releasing an axial securing element of the slide bearing pad to be changed; axially removing the slide bearing pad to be changed through the removal opening; axially inserting a new slide bearing pad through the removal opening; and fixing the new slide bearing pad by the axial securing element. A slide bearing pad changing device with a manipulation arm that is movable relative to a base frame is used for axially removing the slide bearing pad to be changed and for axially inserting a new slide bearing pad, wherein the manipulation arm is configured for coupling with the slide bearing pad.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for changing slide bearing pads arranged on a rotor shaft of a rotor bearing arrangement of a wind turbine, comprising the method steps: moving the slide bearing pad to be changed to a removal opening by rotating the rotor shaft; releasing an axial securing element, or releasing fastening screws, of the slide bearing pad to be changed; axially removing the slide bearing pad to be changed through the removal opening; axially inserting a new slide bearing pad through the removal opening; fixing the new slide bearing pad by means of the axial securing element, or by means of the fastening screws, wherein a slide bearing pad changing device with a manipulation arm is used for axially removing the slide bearing pad to be changed and for axially inserting a new slide bearing pad, wherein the manipulation arm is configured for coupling with the slide bearing pad. 2. The method according to claim 1 , wherein the manipulation arm is coupled with the slide bearing pad by means of a connection element and wherein a form element that interacts with the connection element is configured on a front end of the slide bearing pad. 3. The method according to claim 1 , wherein a base frame is affixed to the rotor shaft by means of a fastening element. 4. The method according to claim 1 , wherein a base frame is affixed to a bearing block by means of a fastening means. 5. The method according to claim 1 , wherein a lifting arm is used for removing the slide bearing pad from the manipulation arm and for affixing a new slide bearing pad to the manipulation arm, wherein the lifting arm is affixed to a circumferential face of the slide bearing pad such that the manipulation arm and the lifting arm can be affixed to the slide bearing pad simultaneously. 6. The method according to claim 1 , wherein the movement of the manipulation arm relative to a base frame of the slide bearing pad changing device is driven by a cordless screwdriver.
