ABSTRACT:
Gerotor pumps are a kind of
internal gear pump, widely used in applications of lubricating system of
on-road or off-road engines. Normally their outer rotors are the circular arc
profile while their inner rotor profile is the conjugate curve of the outer
rotor. This research focuses on how to derive the combined trochoidal profile
of a gerotor pump. The hypocycloidal and epicycloidal profile of the inner
rotor is generated at first. And then the profile of the outer rotor, based on
the inner rotor profile, is obtained by analytical approach and computationally graphical approach. The paper provides feasibility to develop the unconventional profile
of a gerotor pump.
