A gearbox arrangement with an oil circuit, including at least one lubrication point incorporated in the oil circuit and at least one direction control valve with at least two switching positions and at least three ports, the at least three ports including a first port, a second port, and a third port. In a first switching position the first port and the third port are connected to each other in an oil-conducting manner and disconnected from the second port. In a second switching position, the first port and the second port are connected to each other in an oil-conducting manner and disconnected from the third port. The lubrication point and the second port are connected to each other in an oil-conducting manner. The lubrication point and the third port are not connected to each other in an oil-conducting manner.

Bypass for purging an oil circuit

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

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.
