An arrangement including a housing part, a second housing part, a first guide anchor, a second guide anchor, and at least one guide rail. The guide anchors engage form-fittingly and displaceably with the guide rail. The first guide anchor is rigidly fixed to the first housing part and the second guide anchor is rigidly fixed to the second housing part.

Assembling and dissembling device

An arrangement includes a transmission, a pitch tube, and a fixation device configured to affix the pitch tube in the transmission. The fixation device is electrically insulated from the pitch tube. The pitch tube can be axially movable relative to the fixation device. The pitch tube can be fixed in a shaft or a rotatably-mounted planet carrier of the transmission by the fixation device.

Insulated pitch tube

An arrangement including a transmission and a generator is disclosed. The generator includes a generator rotor being non-rotatably connected to an output shaft of the transmission or configured to be connectable to the output shaft of the transmission. An assembly bearing that supports the generator rotor in the output shaft is also disclosed.

Rotational decoupling for assembly and disassembly of a gearbox-integrated mounted generator rotor

A transmission housing includes a first housing half forming a first sealing surface and a first lubricant line, and a second housing half forming a second sealing surface and a second lubricant line. The first sealing surface and the second sealing surface seal an internal space in relation to an environment. An opening of the first lubricant line and an opening of the second lubricant line are fluidically connected to one another. The first sealing surface has a first groove and the second sealing surface has a second groove. The first groove and the second groove together form a third lubricant line. The third lubricant line runs between the opening of the first lubricant line into the first sealing surface and the environment of the transmission housing and between the opening of the second lubricant line into the second sealing surface and the environment of the transmission housing.

Sealing surface having leak-proof passage of an oil channel

An assembly includes a first planetary stage, a second planetary stage, and at least one retainer plate. The first planetary stage has a planet carrier and the second planetary stage has a ring gear. The planet carrier and the ring gear are configured to be rotated about a common axis of rotation. The retainer plate is attached to the ring gear and engages in a groove in the planet carrier. The groove and the axis of rotation are at least partially skewed to each other. The retainer plate is arranged at least partially on a first side of a first plane and on a first side of a second plane. The first plane and the second plane intersect along the axis of rotation. All planet bolts fixed in the planet carrier each lie on a second side of the first plane and/or the second plane.

Retainer plates for fixing planet carrier and ring gear

A planetary carrier for a gear stage of a planetary gearset includes at least one planetary pin that is disposed in a rotationally fixed manner in the planetary carrier, and a pair of tapered roller bearings that are disposed on the planetary pin supporting a planet gear. The planetary pin is fastened by a pin screw connection, which comprises a pin screw and a nut, to the planetary carrier. The tapered roller bearings are clamped against each other between the planetary carrier and the planet pin and are axially pretensioned by the pin screw connection.
