Abstract

The invention relates to a gear train (1), in particular a planetary gear train, for a wind turbine comprising a plurality of gears, in particular planet gears (4), which are each supported on a shaft (8) by means of a bearing element, wherein the bearing element is a multi-layer plain bearing (7).

Description

technical field [0001] The invention relates to a transmission for a wind power plant, in particular a planetary gear, which comprises a plurality of transmission gears, in particular planetary gears, which are each mounted on a shaft via a bearing element, The invention also relates to a wind power plant comprising a rotor and a generator, wherein a gear, in particular a planetary gear, is arranged between the rotor and the generator, which is operatively connected to the rotor and the generator. Background technique [0002] Planetary gears for wind power plants, as known for example from DE 10 260 132 A1, are used for this purpose in order to convert a relatively low rotational speed of a rotor of a wind power plant into a higher rotational speed of a generator rotor. Usually, in such planetary gears, as is also described in DE 10 260 132 A1, rolling bearings are used as bearing elements for the planet gears. [0003] Of course, EP1544504A2 already describes the use of p...
