Abstract: A bearing assembly of a rotor of a wind turbine, for mounting a shaft of the rotor in a fixed housing, wherein the shaft of the rotor is coupled to rotor blades of the rotor via a hub, includes: a plurality of first housing-side axial slide bearing segments engaging on the housing; a plurality of second housing-side axial slide bearing segments; a plurality of first housing-side radial slide bearing segments; and a plurality of second housing-side radial slide bearing segments. An axial distance between the first and second axial sliding surfaces of the rotor defines a bearing length l. The radial sliding surfaces of the rotor on which the first and second radial slide bearing segments are supported, define a bearing diameter d of the bearing assembly, and V≤1 applies to a ratio V=l/d between the bearing length l and the bearing diameter d.

Abstract: A transmission in particular for wind power generators, with an epicyclic planetary gear arrangement having a sun gear, a ring gear, multiple planet gears and a planet carrier. The planet gears have planet gear teeth in mesh with sun gear teeth and ring gear teeth. Each planet gear is rotatably mounted via a radial slide bearing on a planet pin that is non-rotatably connected to the planet carrier. Each slide bearing includes a bearing hub positioned between the planet pin and the planet gear, which is non-rotatably connected to the planet pin. Between the bearing hub and the planet pin an annular support is formed, which seen in the axial direction has a smaller dimension than the bearing hub and/or a smaller dimension than the planet gear teeth of the planet gear.

Abstract: A marine vessel propulsion assembly has an elastically suspended gearbox with an output drive shaft guided in an axial bearing with a rigidly suspended bearing housing. Free space is provided in the axial bearing for allowing movement of the output drive shaft in the radial direction, wherein the output drive shaft is freely movable radially within the free space. A supporting ring with sliding elements for axial guidance of the output drive shaft is arranged in the axial bearing. The supporting ring is hydraulically supported by a large number of pistons so that the supporting ring can match itself to angular displacements of the output drive shaft and can always completely and uniformly support the sliding elements on the bearing circumference.
