Elliptical lobe shape gerotor pump design to minimize wear

Mohammad Reza KARAMOOZ RAVARI

Frontiers of Mechanical Engineering 2011, Volume 6, Issue 4,   Pages 429-434 doi: 10.1007/s11465-011-0247-6

Abstract: Because the gerotor pumps cannot be adjusted for wear so it is important to reduce the wear as much aselliptical lobe shape rotors profile and curvature of them have been derived and then Specific flow and wearrate proportional factor (WRPF) have been formulated.To reach the minimum wear in rotors teeth, the ellipse shape factor is changed for each value of numberof outer rotor teeth in a feasible range and wear rate proportional factor has been resulted.
