Abstract: A wind turbine (10) includes a first connecting structure (36) associated with the main shaft (34) fixed to a second connecting structure (40) of a rotor hub (22). 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) has a peripheral region and a plurality of rotor locking elements (50) in the peripheral region for receiving one or more rotor locking pins (30). The first connecting structure (36) includes at least first and second sets of fastener holes (38a, 38b, 38b?). The first set of fastener holes (38a) is located at a position radially inward of the rotor locking elements (50) and the second set of fastener holes (38b, 38b?) is located between adjacent rotor locking elements (50). The first and/or second set of fastener holes (38a, 38b, 38b?) are used to receive fasteners (39a, 39b) to secure the main shaft (34) to the rotor hub (22).

Abstract: 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.
