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.
