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.

Gearbox assembly with axially adjustable bevel gear

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.

Pulley arrangement for a belt drive and agricultural machine with such

A transmission device and an agricultural harvesting machine include a first drive input element, a second drive input element, a shift sleeve configured as a hollow shaft, and a drive output shaft. The shift sleeve is mounted axially displaceably on the drive output shaft and is configured to be moved by axial displacement into one of a first position, a second position, and a third shift position. An internal toothing is formed on each of the first drive input element and the second drive input element. An external toothing and an internal toothing are formed on the shift sleeve. An external toothing is formed on the drive output shaft.
