WIND TURBINE BLADE BEARING AND SEAL ARRANGEMENT

摘要

A blade bearing for mounting a blade of a wind turbine to a hub of the wind turbine comprises first and second bearing rings arranged next to each other and a seal arrangement covering a space between the first and second bearing rings. One of the first or second bearing rings is configured to mount to the blade, and the other is configured to mount to the hub. The first and second bearing rings each have an axially-facing surface and a radially-facing surface. The seal arrangement includes a first seal element statically coupled to the axially-facing surface of the first bearing ring, a second seal element statically coupled to the axially-facing surface of the second bearing ring, and a holding member secured to the axially-facing surface of the first bearing ring. The first seal element is statically coupled to the holding member. The second seal element is dynamically coupled to the holding member and/or the first seal element.
