    Abstract: A wind turbine nacelle configured for mounting on a wind turbine tower and for supporting a rotor assembly, the nacelle comprising at least a first and a second nacelle module. The first nacelle module comprises a first frame structure and a main bearing system for a main shaft of the rotor assembly, and the second nacelle module comprises a second frame structure and a drive train system for the wind turbine. When the nacelle is mounted on the wind turbine tower, the main bearing system is supported by the wind turbine tower, and the drive train system is attached to the main bearing such that the weight of the drive train system is transferred to the main bearing system and thereby to the wind turbine tower. Further, the first frame structure is configured to support the main bearing system during transportation and prior to mounting of the nacelle, and the second frame structure is configured to support the drive train system during transportation and prior to mounting of the nacelle, and the first and second frame structures form a load carrying structure of a first and a second shipping freight container such that the first and second nacelle module can be transported as shipping freight containers. When the nacelle is mounted on the wind turbine tower, the first and second frame structures may be placed side by side in a direction along a rotational axis of the wind turbine rotor and may be oriented such as to have a length extending transversely to a rotational axis of the wind turbine rotor.

    Abstract: A wind turbine is described which comprises a tower, a nacelle mounted to the top of the tower, and a rotor mounted to the nacelle. The rotor comprises two or more blades mounted to a central hub. The hub supports two or more annular pitch bearings associated respectively with the two or more blades. Each pitch bearing defines a bearing plane inclined at a first angle with respect to a horizontal plane when the respective blade is oriented in a downwardly direction in alignment with the tower. Each pitch bearing is spanned by a hub plate; and a work platform integral with or mounted to the hub plate lies generally in a plane at a second angle to the horizontal plane when the respective blade is oriented in a downwardly direction in alignment with the tower, which second angle is less than the first angle. The work platform provides a substantially horizontal platform for use by maintenance personnel when installing or servicing components in and around the hub.

    Abstract translation: 描述了一种风力涡轮机，其包括塔架，安装到塔架顶部的机舱以及安装到机舱的转子。 转子包括安装到中心轮毂的两个或更多个叶片。 轮毂支撑分别与两个或更多个叶片相关联的两个或更多个环形变桨轴承。 当相应叶片沿与塔架对齐的向下方向取向时，每个变桨轴承限定相对于水平面以第一角度倾斜的轴承平面。 每个变桨轴承都由一个轮毂盘覆盖; 并且与所述毂板成一体或安装到所述毂板的工作平台通常位于相对于所述水平面成第二角度的平面中，当相应的叶片以与所述塔架对齐的向下方向定向时，所述第二角度小于所述第一角度 。 工作平台提供了一个基本水平的平台，供维修人员在轮毂内和周围安装或维修部件时使用。
