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

A transport lock for fixing a planet carrier during transport in a housing-fixed component, including a first part that is joinable to the housing-fixed component, a second part that is joinable to the planet carrier, and at least one bearing, with which the first part and the second part are rotatably supported in one another.

Transportation safeguard with installation bearing

A vibration absorber for securely fixing to the housing of a gearbox includes an absorber mass having a first group of segments that are rotationally symmetrical to one another with respect to a rotational axis and/or central axis of the gearbox. The segments can be rigidly connected to one another. The vibration absorber can further include connectors that are rigidly connected to two segments each.

Segmented vibration absorber

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

An arrangement including a transmission, a feedthrough tube, and a fixing means is disclosed. A fixing means is disclosed whereby the feedthrough tube is fixed in the transmission. The fixing means includes an electrical non-conductor. Arrangements are disclosed in which the feedthrough tube is fixed axially and immovably in the fixing means.

Insulated pitch tube

A unit includes a thrust washer having a first abutment and a second abutment. The thrust washer is configured to be moved, by rotation, between a first position in which the thrust washer abuts the first abutment and a second position in which the thrust washer abuts the second abutment. The first abutment and the second abutment are formed by at least one pin and at least one recess. The pin is configured to engage in the recesses, and the recess is designed as a groove that extends tangentially around an axis of rotation of a component that is rotatably mounted by way of the thrust washer.

Pivoting thrust washer

An arrangement includes a first component having a first groove and a second groove. The arrangement further includes a second component and a fluid transfer ring fixed to the second component. The fluid transfer ring engages with a first wall and a second wall in the first groove such that the fluid transfer ring and the first groove form a first cavity. The first component and the second component are rotatable relative to each other. The fluid transfer ring further engages with a third wall in the second groove such that the fluid transfer ring and the second groove form a second cavity.

Lubricant transfer ring having a plurality of chambers

An arrangement including a transmission housing forming a lubricant sump and a pipeline including a first piece and a second piece. The first piece and the second piece of the pipeline respectively open into the lubricant sump. The first piece and the second piece of the pipeline are inserted into one another.

Oil drainage

A fastener for a transmission part includes a main body. The main body has at least one external screw thread and at least one through-hole. The fastener further includes a first pin displaceable in a first region of the through-hole and a second pin having an external screw thread. A second region of the through-hole has at least one internal screw thread configured to be screwed to the external screw thread of the second pin. The second pin has a through-hole. The first pin has an internal screw thread aligned with the through-hole of the second pin.

Fastener for heavy transmission parts

A transmission includes at least one planetary gear stage with a planet carrier having a first toothing. The transmission further includes at least one lubricant line having a first outlet opening and a second outlet opening. The first toothing, together with a second toothing, forms a spline. The first outlet opening is configured to lubricate the spline, and the second outlet opening is configured to lubricate a sun gear of the planetary gear stage.

Branched lubricant line

An arrangement includes a first oil line, a second oil line, a third oil line, a cavity, and a plate having a continuous first hole and a continuous second hole. The first oil line, the second oil line and the third oil line each have a mouth in the cavity. The plate is arranged in the cavity in such a way that it covers the mouths of the second oil line and the third oil line. The first hole connects the second oil line and the cavity to each other in a fluid-conducting manner. The second hole connects the third oil line and the cavity to each other in a fluid-conducting manner.

Oil distributor

A planetary stage includes a planetary carrier, at least one pitch tube, and at least one fixing element. The pitch tube is arranged coaxially to a rotation axis of the planetary stage. The pitch tube extends through a wall of the planetary carrier. The fixing element is fixed in the wall. The pitch tube has a groove. The fixing element engages in at least one part of the groove, wherein the at least one part of the groove extends orthogonally to the rotation axis. A plate is fixed in the wall, and the fixing element engages in a clearance between the wall and the plate and is fixed positively between the wall and the plate.
