Abstract
A seal arrangement for sealing a bearing comprising a first component and a second component which are rotatably movable with respect to each other is provided. The seal arrangement includes brush seal having an annular brush body carried by the first component and a bundle of resiliently bendable bristles. The brush seal is adapted to maintain a sealing condition when the first and second component are moved relative to each other in a non-rotational manner. Further, a brush seal and a wind turbine having a brush seal are provided.

A seal arrangement for sealing a bearing comprising a rotational axis, a first component and a second component, at least one of the first component and the second component being rotatably movable around the rotational axis, the seal arrangement comprising a brush seal comprising a bundle of resiliently bendable bristles and an annular brush body which is carried by the first component, the brush seal being adapted to maintain a sealing condition when the first component and the second component are moved relative to each other in a non-rotational manner.
A brush seal for a bearing between a first part and a second part of a wind turbine, the bearing comprising a rotational axis, an inner annular member fastened to the first part, an outer annular member fastened to the second part and a circumferential gap therebetween, the brush seal comprising a plurality of flexible bristles sealing the circumferential gap such that they are pre-stressed in a plane which comprises the rotational axis.
A wind turbine comprising a first part and a second part, the second part being pivot-mounted with respect to the first part using a rolling-element bearing comprising a lubricant and a rotational axis, the wind turbine further comprising a brush seal comprising a bundle of resiliently bendable bristles, and being adapted to prevent at least one of leakage of the lubricant and penetration of dust when the first part and the second part are moved relative to each other in a non-rotational manner.
