Abstract
A gear pump rotor assembly is disclosed. In order to prevent that the gear toothing is cooled in an unreliable manner, radial heat flow is reduced in the toothing area of the shaft, preferably by means of an insulation air chamber or other insulated section, with respect to the heat flow in other shaft areas to be cooled.
