Planetary gear, wind generator with planetary gear and use of a planetary gear

摘要

A planetary gear and a wind generator, in particular an off-show wind generator, comprising this planetary gear is provided. The planetary gear comprises a drive wheel engaging a transmission stage having first planetary gears, which are coupled to a number of second planet gears being axially displaced with respect to the first planet gears. The second planet gears engage a sun wheel, which is coupled to a driven shaft. The drive wheel is a hollow wheel having an internal gear. The second planet gears are divided into a first subset and a second subset of gears. The two subsets of gears are arranged in two separate planes being spaced from each other in an axial direction. Furthermore, the second planet gears of the first subset are arranged inside an interior space of the drive wheel.
