Abstract
A powertrain for a wind power installation includes a main bearing unit with a main shaft, and a planetary transmission driven by the main shaft and including a transmission housing and a planetary stage which revolves about a rotation axis in the transmission housing. The planetary stage includes a planet carrier, a ring gear, and a sun gear, with the planet carrier or the ring gear being drivingly connected, at least indirectly, to the rotor. The planet carrier includes planet gears which revolve conjointly with the planet carrier and alternately mesh with the ring gear and the sun gear. At least three guide elements disposed circumferentially about the rotation axis are each operatively connected alternately to the transmission housing and a circumferential region of the planet carrier. Each guide element is constructed of multiple parts and includes guide jaws disposed on axial sides of the planet carrier, respectively.
