ABSTRACT:
The invention relates to a transmission arrangement (10). Said transmission arrangement (10) comprises a transmission housing (16), a transmission chamber (12) surrounded by the transmission housing (16), a first shaft (20) mounted in the transmission housing (16), a cavity (88) embodied in the first shaft (20) eccentrically to the rotational axis (18) with the cross-sectional centre of gravity thereof, and a channel (156) embodied in the first shaft (20). Said channel (156) connects the transmission chamber (12) to the cavity (88) of the first shaft (20). The aim of the invention is to improve the lubrication process of the transmission arrangement (10) and the operating reliability, thus extending the maintenance intervals. To this end, the channel (156) is provided with a component (162) which is used to reduce the passage cross-section of the channel (156), and by which means only an optimised quantity of lubricant is transported through the channel (156). One such transmission arrangement is used for example for driving a cutter on a combine harvester.
