Powertrain mounting for planetary transmission

A powertrain for a wind power installation driven by a rotor for torque-transmitting connection of the rotor to a generator, the power train comprising:

• a main bearing unit comprising a bearing housing and a main shaft;
• a planetary transmission driven by the main shaft, said planetary transmission comprising a transmission housing and at least one planetary stage which revolves about a rotation axis in the transmission housing, said at least one planetary stage comprising a planet carrier, a ring gear, and a sun gear, with the planet carrier or the ring gear being operatively connected, at least indirectly, to the rotor, said planet carrier comprising a plurality of planet gears which revolve conjointly with the planet carrier and alternately mesh with the ring gear and the sun gear;
• and
• at least three guide elements disposed circumferentially about the rotation axis and each operatively connected alternately to the transmission housing and a circumferential region of the planet carrier, each of said guide elements constructed of multiple parts and comprising guide jaws disposed on axial sides of the planet carrier, respectively.
