Title: TRANSMISSION, IN PARTICULAR FOR THE POWERTRAIN OF RAIL VEHICLES
Abstract:
The invention relates to a transmission, in particular for use in a powertrain of a rail vehicle, having a part (1) which is rotatable about a rotation axis, at least one duct (4) running within the rotatable part (1) and having an inlet opening (5) to allow lubricant into the duct (4) and an outlet opening (25) to allow lubricant out of the duct (4). As viewed in a longitudinal section, containing the rotation axis, through the rotatable part, at least one longitudinal section of the duct (4) has an inner edge (28) which runs closer to the rotation axis in the radial direction relative to the rotation axis and an outer edge (29) which runs at a greater distance from the rotation axis, and the outer edge (29) extends further away from the rotation axis as the at least one longitudinal section runs towards the outlet opening (25).
