Abstract

In accordance with a method for assembling a rotor bearing arrangement of a wind turbine, individual slide bearing pad are inserted in the bearing block. The bearing block fitted with the slide bearing pads is then joined to a rotor block. During the joining of the rotor shaft and of the bearing block fitted with the slide bearing pads, the rotor shaft may be installed on a rotor shaft support so as to be vertically upright. A rotor shaft flange of the rotor shaft may rest on the rotor shaft support. The bearing block fitted with the slide bearing pads may be placed upon the rotor shaft vertically from above.

First claim

1 . A rotor bearing arrangement assembling device for assembling a rotor bearing arrangement of a wind turbine, the device comprising:
a receiving device with a receiving carriage configured for receiving a bearing block fitted with slide bearing pads, wherein the receiving device comprises a base frame coupled with the receiving carriage via a linear guide, such that the receiving carriage is displaceable in a vertical direction; and a rotor shaft support configured such that, during a joining of a rotor shaft and the bearing block fitted with the slide bearing pads, the rotor shaft is installed on the rotor shaft support so as to be vertically upright; wherein a rotor shaft flange of the rotor shaft rests on the rotor shaft support and wherein the bearing block fitted with the slide bearing pads is placed upon the rotor shaft vertically from above.

2 . The rotor bearing arrangement assembling device according to claim 1 , wherein the linear guide is aligned vertically, so that the receiving device is displaceable in a vertical direction.

3 . The rotor bearing arrangement assembling device according to claim 1 , wherein the rotor shaft support is displaceable relative to the receiving device in a horizontal direction.

4 . The rotor bearing arrangement assembling device according to claim 3 , further comprising:
a base coupled with the rotor shaft support; and a base frame of the receiving device mounted on the base via a linear guide so as to be displaceable.

5 . A method for assembling a rotor bearing arrangement of a wind turbine, comprising the steps of:
providing a rotor shaft; providing a bearing block; providing individual slide bearing pads; inserting the slide bearing pads in the bearing block; and joining the rotor shaft and the bearing block fitted with the slide bearing pads; wherein a connection ring is provided, via which the slide bearing pads can be temporarily coupled with the outer ring element and/or can be temporarily held in the outer ring element.

6 . A method for assembling a rotor bearing arrangement of a wind turbine, comprising the steps of:
providing a rotor shaft; providing a bearing block; providing individual slide bearing pads; inserting the slide bearing pads in the bearing block; and joining the rotor shaft and the bearing block fitted with the slide bearing pads; wherein each time after placing one of the slide bearing pads in the bearing block, this slide bearing pad just placed in the bearing block is affixed to the bearing block by means of a connector.
