Abstract

ABSTRACT OF THE INVENTION

A spur pump gear system comprising; a housing have a sealed chamber communicating with an intake port and a discharge port; a shaft journalled for rotation within said chamber; a drive spur gear mounted concentrically on said shaft about a first axis within said chamber and having a drive gear pitch circle, said drive spur gear having epi and hypo cycloid tooth profiles generated about the pitch circle of the drive spur gear;
a driven spur gear disposed internally within said chamber for rotation about a second axis and having a driven gear pitch circle, said driven spur gear having epi and hypo cycloid tooth profiles generated about the pitch circle of the driven gear;
said epi hypo cycloid tooth profile of said drive spur gear engagedly driving said hypo cycloid tooth profile of said driven spur gear.
