Abstract:
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).
