Abstract
A bearing for a wind turbine, the use of the bearing and a method to control the temperature of the bearing is provided. A bearing for a wind turbine comprises an inner ring and an outer ring. The inner ring and the outer ring are prepared and arranged in a way to rotate with respect to each other. The inner ring comprises at least one channel. The channel is prepared and arranged in a way that air flows along inside the channel so that excess heat of the inner ring is removed by the airflow in the channel.
Claims20
A bearing for a wind turbine comprising:
- an inner ring and an outer ring, the inner ring and the outer ring prepared and arranged in a way to rotate with respect to each other;
- and
- an extruded profile component that forms at least one channel, the extruded profile component attached to the inner ring, the at least one channel prepared and arranged in a way that air flows along inside the at least one channel, so that excess heat of the inner ring is removed by the air flow in the at least one channel.
A bearing for a wind turbine comprising:
- an inner ring and an outer ring, the inner ring and the outer ring prepared and arranged in a way to rotate with respect to each other;
- wherein the inner ring comprises at least one channel, the at least one channel prepared and arranged in a way that air flows along inside the at least one channel so that excess heat of the inner ring is removed by the air flow in the at least one channel;
- wherein the at least one channel is formed by an extruded aluminum profile that is at least partially covered by a lid and that is arranged at a surface of the inner ring.
A bearing for a wind turbine comprising:
- an inner ring and an outer ring, the inner ring and the outer ring prepared and arranged in a way to rotate with respect to each other;
- wherein the inner ring comprises at least one channel, the at least one channel prepared and arranged in a way that air flows along inside the at least one channel, so that excess heat of the inner ring is removed by the air flow in the at least one channel;
- wherein a ventilator is arranged at least at one opening of the at least one channel, in a way that the ventilator moves air through the opening of the at least one channel and through the at least one channel;
- wherein the ventilator is arranged at the at least one channel in a way that the ventilator overlaps the at least one channel at the opening of the at least one channel, so that the ventilator moves air through the at least one channel.
