Abstract
A sliding bearing arrangement for a wind turbine and a method to service the bearing is provided. A sliding bearing arrangement of a wind turbine includes a first shaft and a second shaft, whereby a first radial sliding bearing is arranged between the shafts. The first radial sliding bearing includes bearing pads. The first shaft includes a collar, whereby the collar is arranged mainly perpendicular to the axis of rotation, and radially overlaps at least a part of a radial surface of the second shaft. The collar includes an opening to exchange the bearing pads of the first radial sliding bearing of the bearing arrangement.
Claims15
A sliding bearing arrangement of a wind turbine, wherein the arrangement comprises a first shaft and a second shaft, the first shaft and the second shaft being arranged coaxially to each other, and one of the first shaft and the second shaft shafts is rotatable with respect to the other shaft around a common axis of rotation,
- wherein a first radial sliding bearing is arranged between the first shaft and the second shaft to support the rotatable shaft by the stationary shaft,
- wherein the first radial sliding bearing comprises bearing pads,
- wherein the first shaft comprises a collar, the collar being arranged mainly perpendicular to the common axis of rotation, and radially overlaps at least a part of a radial surface of the second shaft,
- wherein the collar comprises a first axial sliding bearing to support axial loads between the first shaft and the second shaft,
- wherein the collar is connected to the first shaft at a first radial position of the collar, and the first axial sliding bearing is connected to the collar at a second radial position of the collar,
- wherein the collar comprises an opening in an area between the first radial position and the second radial position, to exchange the bearing pads of the first radial sliding bearing of the sliding bearing arrangement.
A method for exchanging a bearing pad of a sliding bearing arrangement of a wind turbine, wherein the sliding bearing arrangement comprises a first shaft and a second shaft, wherein the first shaft and the second shaft are arranged coaxially to each other, and one of the first shaft and the second shaft is rotatable with respect to the other shaft around a common axis of rotation,
- wherein a first radial sliding bearing is arranged between the first shaft and the second shaft to support the rotatable shaft by the stationary shaft,
- wherein the first radial sliding bearing comprises bearing pads,
- wherein the first shaft comprises a collar, wherein the collar is arranged mainly perpendicular to the common axis of rotation, and radially overlaps at least a part of a radial surface of the second shaft,
- wherein the collar comprises a first axial sliding bearing to support axial loads between the first shaft and the second shaft,
- wherein the collar is connected to the first shaft at a first radial position of the collar, and the first axial sliding bearing is connected to the collar at a second radial position of the collar,
- wherein the collar comprises an opening in an area between the first radial position and the second radial position,
- the method comprising the step of:
- exchanging a bearing pad of the first radial sliding bearing through the opening in the collar of the first shaft.
