PUMP DRIVE FOR THE PUMP OF A RETARDER

摘要

The invention relates to a pump drive for the pump of a retarder, whereby said pump is driven by the rotor of the retarder by means of a coupling, connecting the rotor shaft and the pump shaft (2) together. According to said invention, the coupling between the rotor shaft and the pump shaft (2) is embodied as a transversally-flexible coupling for compensating parallel radial misalignments and small axial displacements of the rotor shaft and the pump shaft (2) in relation to each other.
