Abstract

The invention relates to a wind turbine with a rotor and a generator. A planetary transmission (1) is arranged between the rotor and the generator, said planetary transmission being operatively connected to the rotor and the generator. The planetary transmission (1) has at least one planet gear (4), at least one planet pin (7), and a planet carrier (8), said planet gear (4) being arranged on the planet pin (7). At least one sliding bearing (15, 16) is arranged between the planet pin (7) and the planet carrier (8), and the planet gear (4) is connected to the planet pin (7) in a manner incapable of relatively rotating.

Description

technical field [0001] The invention relates to a wind power generating equipment, which comprises: a rotor and a generator, a planetary gear device is arranged between the rotor and the generator, and the planetary gear device is operatively connected with the rotor and the generator, wherein the The planetary gear has at least one planet gear, at least one planet pin and a planet carrier, and the planet gear is arranged on the planet pin. Background technique [0002] As is known from DE 10 260 132 A1, a planetary gear arrangement for a wind power plant that generates electricity is used to convert a lower rotational speed of a rotor of a wind power plant into a higher rotational speed of a generator rotor. Roller bearings are usually used in such planetary gearings as support elements for the planetary gears, as is also described in DE 10 260 132 A1. However, the prior art also describes sliding bearings as supporting elements, for example EP1544504A2 or AT509624A1. [...
