A transmission housing () has at least one bead () for forming one or more housing feed-through passages (). A method of producing the transmission housing and a transmission series are also disclosed.

Bead for housing bushings

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.

Planetary gear mechanism with adjustable ring gear

A wind power plant has a rotor, an integrated medium-speed electric generator, and a planetary transmission. The planetary transmission is arranged to convert a slow rotary motion of the rotor into a rapid rotary motion to operate the generator. The planetary transmission includes a transmission input shaft connected indirectly to the rotor and includes a transmission output shaft connected to the generator indirectly via a generator shaft. A coupling mechanism is arranged between the generator shaft and the planetary transmission to compensate axial, radial and angular misalignment.
