ABSTRACT:
A gear pump or a hydraulic gear motor has two pairs of meshing external gears, in which the teeth of one of the gears of each pair of gears are circumferentially displaced with respect to the teeth on the other gear of the pair. The gears arranged on the drive shaft are connected by the latter by an internal gearing, especially by splines, whereby the number of the teeth of the internal gearing is an even multiple, especially twice, the number of the external teeth of these gears.
