Abstract: A technique facilitates control over the orientation of a bottom hole assembly. A planetary gearbox assembly incorporates a sun wheel which cooperates with planet wheels at a plurality of levels along the planetary gear box assembly. The sun wheel and the planet wheels cooperate to convert rotational input to rotational output through an output carrier. Torsional rigidity characteristics of the sun wheel and the output carrier are selected to distribute torque loading across the plurality of levels of the planetary gear box assembly. The distributed forces reduce the potential for component failure.

Abstract: A drive assembly for a wind turbine includes a rotor hub, a supporting structure, a planetary gear transmission unit having sun, planet and ring gears and a planet carrier. The ring gear is non-rotatably secured to the supporting structure. A main bearing rotatably supports the rotor hub and planet carrier relative to the ring gear and supporting structure. The drive assembly further includes two substantially independent force transmission paths for transmission of forces reacting with forces exerted by the wind turbine rotor hub. A first of the force transmission paths acts from the rotor hub via the main bearing to the supporting structure primarily for transmission of overhang load forces and bending moment forces and a second of the force transmission paths acts from the rotor hub via the planet carrier primarily for transmission of rotational forces.

Abstract: A wind turbine with a rotor, a nacelle and a tower. The nacelle comprises a planetary gear (4) with a planetary holder (5), on which the hub (6) of the rotor is rigidly secured, and which can be connected to the shaft of an electric generator. The planetary gear (4) comprises a ring gear (7) fixedly mounted on an engine frame (9) in the nacelle or on the member (8) rigidly connected to said frame. The planetary wheels (17a, 17b) of the planetary gear can run around a centrally arranged sun wheel (14) while engaging the latter. The sun wheel is optionally connected to a parallel gear (30). The planetary holder (5) is rotatably mounted in the ring gear (7) by means of at least two sets (17) of planetary twin wheels (17a, 17b). Each set of planetary twin wheels is mounted on a bogie shaft (19) on the planetary holder. Through an axially rearward collar (23) projecting beyond the ring gear, the planetary holder (5) is also rotatably arranged on the curved outer side (7b) of the ring gear (7) by means of an outer radial-axial-roller bearing (27). As a result, a wind turbine is obtained which is suited for generating very strong power and which is very compact and ensures a very advantageous transfer of the power at each planetary wheel.
