A gear assembly includes a planetary gear set having a sun gear, planet gears, and a ring gear. The planet gears are respectively rotatably mounted by a bearing on a respective planetary pin. The respective planetary pin is connected to a planetary carrier. Tilting pads arranged radially circumferentially with respect to the planetary pin are provided on sides of the planetary carrier facing the planet gears. The planetary carrier has, on sides facing the planet gears, recesses arranged radially circumferentially with respect to the planetary pin and corresponding to the tilting pads. The recesses are configured to receive at least part of the tilting pads.

Transmission assembly comprising axial tilt segments

A system for emergency lubrication, with a lubricant pump () and with at least one outlet opening () for delivering lubricant to at least a first lubrication point () of a transmission (), in particular a transmission of a wind turbine. The system includes a first cavity (), and the lubricant pump () is designed to convey at least some of the lubricant into the first cavity (). The first cavity () is designed to store the lubricant intermediately and to act upon the intermediately stored lubricant with positional energy. In addition, there is a lubricant-conveying connection between the first cavity () and the outlet opening ().

Emergency lubrication for wind turbine gearboxes

A planetary gear stage for a gearbox has a ring gear, a sun gear and a planet carrier for driving planet shafts. Each planet shaft has a planet gear with radial and axial contact surfaces and which is rotatably supported by a plain bearing arrangement. The bearing arrangement has two bushings fixed to the planet shaft. Each bushing is L-shaped in cross-section and has radial and axial contact surfaces. The bushings form a cross-sectional U-shape and are axially locked by abutments. At least part of the planet gear is located within the U-shape formed by the bushings. The plain bearing arrangement has a radial sliding support arranged between the radial contact surface of the bushings and the radial contact surface of the planet gear and an axial sliding support arranged between the axial contact surface of the bushings and the axial contact surface of the planet gears.

Planetary gear stage with plain bearings as planet bearings and use thereof

A planetary type gear transmission unit () suitable for a wind turbine () includes sun (), planet () and ring () gears and a planet carrier (), the planet carrier () including a planet bogie plate () which supports and locates circumferentially spaced pairs of planet gears () a planetary type gear transmission unit () includes sun (), planet () and ring gears () and a planet carrier(), the planet carrier () including a planet bogie plate () which supports and locates circumferentially spaced pairs of planet gears (), the sun () and ring gears () being each of the double helical type and each of the planet gears () of a pair being of the single helical type and of a helix angle opposite to that of the other planet gear () of the pair.

Gear transmission unit with planetary gears

A gearbox for a wind turbine which consists of a housing and a gear wheel transmission with an ingoing shaft having at least one driving gear wheel which is or can be connected to the rotor of the wind turbine, characterized in that, in the unloaded condition of the gearbox, the axis of symmetry of the seating or seatings of the bearing of the ingoing shaft in the housing does not coincide with the geometrical axis of symmetry of the gear wheel transmission, as a result of which there will be a certain deviation between the abovementioned axes of symmetry in the unloaded condition which is such that, in a static, loaded condition, in other words under the weight of the rotor, the alignment error which is caused by the weight of the rotor is at least partially compensated.

Gearbox for a wind turbine

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.

Drive assembly for wind turbines

In a gear unit for use in wind turbines and of the kind with a planetary gear stage, and an integrated main rotor bearing that is adapted to provide location for the rotor hub relative to the wind turbine nacelle and to locate the planet carrier relative to a low speed ring gear, the forces due to bending moments acting between the rotor hub and nacelle are transmitted substantially directly from the rotor hub to the nacelle via the main bearing and substantially none of the bending moments are transmitted to the nacelle via the ring gear of the planetary gear stage.
