A gearbox assembly including a gearbox housing in which a first shaft with a first bevel gear and a second shaft with a second bevel gear are rotatably mounted, the first and second shafts enclosing an angle to each other, the first shaft being supported in a quill equipped with an external thread which interacts with an internal thread of the gearbox housing so that an axial adjustment of the first shaft occurs by turning the quill in relation to the gearbox housing, the quill being supported in the radial direction by a surface of the quill axially spaced from the external thread on a complementary surface of the gearbox housing, and the surface of the quill and complementary surface of the gearbox housing being conical and tapering towards the second shaft.

A pulley arrangement for a belt drive including an input shaft having first end and second end. The first end of the input shaft is couplable to a gear box. Further, the pulley arrangement includes a pulley mounted coaxially on the input shaft having an inner pulley surface and an outer pulley surface. The pulley arrangement further includes at least one ring disc. The at least one ring disc is fastened coaxially to the inner pulley surface or the outer pulley surface. A plurality of air flow directing protrusions, grooves, or both protrusions and grooves extend from an inner diameter to an outer diameter of the ring disc, and a circumferential ring disc gap is provided between the at least one ring disc and the input shaft.

A gerotor pump arrangement for extracting hydraulic fluid from a transmission housing of a transmission. A first gerotor set has a first inner rotor and a first outer rotor, and a second gerotor set has a second inner rotor and a second outer rotor. The first gerotor set forms a hydraulically drivable drive side of the gerotor pump arrangement, and the second gerotor set forms a pump side, driven by the first gerotor set, wherein the first and second inner rotors are rotationally fixedly mounted on a common shaft which is rotatable about a rotational axis. A transmission with such a gerotor pump arrangement is also disclosed.

A lubrication arrangement includes at least one housing, at least one shaft, at least one bearing system configured to hold the at least one shaft in the at least one housing and to permit the at least one shaft to rotate, lubricant distributed in the at least one housing with the rotation of the at least one shaft, and a lubricant deflector provided in a stationary manner relative to the at least one housing above the at least one shaft. The lubricant strikes against the lubricant deflector and, by action of gravity, the lubricant is conducted to the at least one bearing system of the at least one shaft so that the at least one bearing system is supplied with the lubricant.

A switching device for a transmission have a first and a second transmission housing portion. The switching device comprises a shift collar, a shift fork which engages in the shift collar, a control actuator which is arranged in the first transmission housing portion and an actuator rod which is connected at one end to the control actuator and at the other end to the shift fork. The actuator rod is supported in a first guiding hole which is formed in the first transmission housing portion. It is proposed that a second guiding hole which is formed in the first transmission housing portion parallel with the first guiding hole be formed and a guide rod which is orientated parallel with the actuator rod be provided and be connected at one end to the shift fork and at the other end be supported in the second guiding hole.

Feederhouse gearboxes are provided for installation on combine harvesters. In embodiments, the feederhouse gearbox includes a gearbox housing, an output shaft rotatable about an output axis, and a primary drive input. The primary drive input is mechanically linked to an engine of the combine harvester when the feederhouse gearbox is installed thereon. A reverser drive input is mechanically linked to a reverser motor of the combine harvester when the feederhouse gearbox is installed on the combine harvester. The feederhouse gearbox further includes a selector mechanism within the gearbox housing and movable between a primary drive position and a reverser drive position, a primary gear train transmitting rotation from the primary drive input to the output shaft when the selector mechanism is in the primary drive position, and a reverser worm drive transmitting rotation from the reverser drive input to the output shaft when the selector mechanism is in the reverser drive position.
