Abstract
A bearing for attaching a wind turbine blade to a wind turbine hub, includes a stationary ring, a movable ring which can rotate relative to the stationary ring, a grease lubrication structure, and a canister for collecting grease. The grease lubrication structure forms an outlet for releasing grease from a space between the stationary ring and the movable ring and the canister comprises an inner space with at least one inlet in releasable fluid communication with the outlet. The outlet and the inlet comprise cooperating coupling elements adapted for releasable snap-connection of the outlet to the inlet. Due to the snap-connection, the canister is easily removed and replaced in connection with maintenance of the wind turbine even though the space in the hub is typically very limited.
