Abstract

A planetary gear mechanism, in particular for wind power plants, includes at least one planetary gear stage that has two power-split planetary stages connected in parallel. At least one of the two planetary stages includes a ring gear which is operatively connected to a housing. At least three planetary gear wheels are arranged on an inner circumferential face of the ring gear. The ring gear is flexible in the radial direction and is configured to be adjustable in order to compensate load between the at least three planetary gear wheels and the ring gear.
