A wind turbine including a nacelle and a rotor hub is disclosed. The nacelle may extend between a hub end and an aft end and may define a nacelle shaft opening and a nacelle access port at the hub end. The rotor hub may extend between a first end and a second end, with the second end being disposed adjacent to the hub end of the nacelle. The rotor hub may also define a hub shaft opening at the second end and a hub access port generally adjacent to the hub shaft opening. In addition, the wind turbine may include an access bridge configured to extend between the nacelle and the rotor hub so as to provide access between the nacelle access port and the hub access port.

A system and method for lubricating gears in a wind turbine blade pitch drive are provided, wherein the pitch drive comprises a drive pinion gear with gear teeth that engage a pitch bearing gear coupled to a respective wind turbine blade. A grease distributor is configured to mount onto and rotate with the pinion gear, and is configured to deliver grease from an external grease supply to at least one valley defined between adjacent teeth of the pinion gear in a contact area of the pinion gear with the bearing gear without the distributor contacting inter-engaging teeth of the bearing gear.
