AB  - In order to solve the problem of radial pressure existed in current gear pumps, an unordinary pump
called flexspline gear pump is invented in this study where the pumping function for fluid is achieved by the
inner gearing between two gears of flexspline and circular spline. The necessary aspects regarding the
composition, operating principle, features and calculation of the new gear pump are provided. Excellent
performances of the new pump are respresented by its balanced radial pressure on the drive shaft, double
displacement and longer service life of the pump. The proposed new pump offer innovative ideas for upgrading
the classical gear pumps.
