摘要： The present invention provides a segmented pitch ring for use in a blade pitch system of a wind turbine. The segmented pitch ring is formed of a plurality of segments manufactured by different processes. In particular, one or more of the segments are formed by a rolling process, and one or more of the segments are formed by a casting process. The segments are arc-shaped or include arc-shaped sections that in combination define a substantially circular circumference of the pitch ring.

摘要： A connection system for joining two wind turbine components together includes one or more bearing surfaces and one or more support surfaces extending away from the one or more bearing surfaces on a first wind turbine component, and one or more bearing surfaces and one or more support surfaces extending away from the one or more bearing surfaces on a second wind turbine component. One or more bores are formed in the one or more support surfaces of the first and second wind turbine components. One or more pins are configured to be engaged with respective one or more bores of the first and second wind turbine components to thereby join the two components together. A method for joining two wind turbine components together is also disclosed.

摘要： A wind turbine includes a main shaft (34), a rotor hub (22), a plurality of blades coupled to the rotor hub (22), and a rotor locking disc (32), (32′). The main shaft (34) includes a front end portion (34a), and the front end portion (34a) includes a first connecting structure (36). The rotor hub (22) includes a second connecting structure (40). The first connecting structure (36) of the main shaft (34) is fixed to the second connecting structure (40) of the rotor hub (22). The rotor locking disc (32), (32′) is integrally formed on the front end portion (34a) of the main shaft (34), and includes a peripheral region. A plurality of rotor locking elements (50), (50′) are located in the peripheral region for receiving one or more rotor locking pins (30).

摘要： Support structures of a wind turbine, including a bearing housing that supports bearings that allow a rotor shaft to rotate about a rotor axis. The bearing housing may be constructed to minimize forces in the bearings in response moments that act on the rotor shaft about axes other than the rotor axis. The support structures of the wind turbine may also include a base to which the bearing housing may be mounted. The base may include features that minimize stress within the wind turbine structure and/or a yaw mechanism of the wind turbine in response to moments that act within the wind turbine about axes other than the rotor axis.

摘要： A wind turbine (10) includes a main shaft (34) including a front end (34a), the front end (34a) including a first connecting structure (36). A rotor hub (22) includes a second connecting structure (40), wherein the second connecting structure (40) of the rotor hub (22) is fixed to the first connecting structure (36) of the main shaft (34). A plurality of blades (24) is coupled to the rotor hub (22). A rotor locking disc (32) is carried on the main shaft (34), the rotor locking disc (32) having an outer circumference (32a) and a plurality of recesses (50) on the outer circumference (32a), the recesses (50) having openings (50a) intersecting with the outer circumference (32a). At least one rotor locking pin (30) is movable between a disengaged position relative to at least one of the recesses (50) and an engaged position wherein the pin is located at least partially in one of the recesses (50) for locking the rotor hub (22) against rotation.
