Abstract:
A novel crescent gear pump and pump rotor set for a crescent gear pump. The rotor set includes an outer rotor with teeth having a composite profile formed over the portion adjacent their root to conform to a circular arc and formed over the portion adjacent their tip to conform to a hypocycloid arc. The unique shape allows for increased volumetric capacity of the rotor set, when compared to trochoidal rotor sets of the same size. Further, operating noise is reduced, as are pulsations in the output of the pump when compared to the same pump with a trochoidal rotor set.
