| 发明名称 | Wind turbine blade bearing and wind turbine that makes use thereof | ||
| 摘要 | A wind turbine blade bearing with a fixed ring fixed to a hub of the wind turbine and a moving ring whereto the blade is fixed by corresponding fixing elements; the bearing making it possible to avoid the collision of the blade with the wind turbine tower by providing a separation therebetween via the disposal of the blades at an angle with respect to the wind turbine hub; where the angle is given by the bearing of the blade pitch change system. The separation is achieved since a rear face of the moving ring is in contact with the blade so that a plane defined by the rear face is perpendicular to the longitudinal direction of the blade, the rear face not being perpendicular to the axis of rotation of the bearing. | ||

| 主权项 | 1. Wind turbine comprising at least one blade and a bearing, the bearing comprising a fixed ring fixed to a hub of the wind turbine, and a moving ring whereto the blade is fixed by a corresponding fixed connection, wherein a rear face of the moving ring is in contact with the blade so that a plane defined by the rear face is perpendicular to the longitudinal direction of the blade, and the rear face is not perpendicular to the axis of rotation of the bearing such that, when the blade is in a position in which the wind thrust is maximum, the separation between the blade and a tower of the wind turbine is greater than the separation in a case where the rear face of the moving ring is perpendicular to the axis of rotation of the bearing. | ||
