Claim 0:
1. A gearwheel arrangement, comprising:
a gearwheel configured to be rotatable about an axis of rotation, the gearwheel comprising a gearwheel body and an annular gear tooth section extending around the gearwheel body, the gear tooth section comprising a plurality of external gear teeth,
wherein at least a part of the gear tooth section extends past a radially outer portion of the gearwheel body in an axial direction of the gearwheel, so that at least one radially inwardly facing surface is provided opposite of the external gear teeth, means for guiding cooling fluid toward the at least one radially inwardly facing surface so as to cool the gear tooth section during rotation of the gearwheel about the axis of rotation,
wherein the at least one radially inwardly facing surface comprises a first annular surface extending between a first side surface of the gear tooth section and a first side surface of the gearwheel body, and a second annular surface extending between a second side surface of the gear tooth section and a second side surface of the gearwheel body, the first and the second annular surfaces being formed on axially opposite sides of the radially outer portion of the gearwheel body,
wherein the means for guiding cooling fluid toward the at least one radially inwardly facing surface comprises a conduit, which is formed within the gearwheel body, the conduit being configured for receiving cooling fluid provided via a shaft on which the gearwheel is mounted, the conduit having a first outlet provided just radially inside of the first annular surface, and a second outlet provided just radially inside of the second annular surface, via which cooling fluid may be provided to the at least one radially inwardly facing surface, and
wherein the gear tooth section comprises an annular flange delimiting the at least one radially inwardly facing surface in the axial direction.
