Gerotor pumps are internal gear pumps used in the lubrication system of the engine and transmission of auto mobiles. In addition, all-wheel drive(AWD) systems adopt them for the purpose of controlling the hydraulic system. In the automobile industry, improvements in fuel efficiency and noise reduction hae recently come to the fore. In this paper, a new type of gerotor is designed on Megafloid. It is composed of Hypocycloid curves, Epicycloid curves and tangent line between two curves. We modeled the three types rotor of Megafloid design, simulated by analyzing the internal fluid flow using a commercial computation fluid dynamics-code(CFD), and compared the volume effiiency.

In this paper, Three gear shapes of the gerotor pump are studied. First, a trochoid profile was illustrated using the cycloid curve. Secondly, a tooth profile which connected to the epicycloid curve and the hypocycloid curve was illustrated. Finally, it was illustrated a tooth tangent curve connected between Hypocycloid curve and epicycloid curve. The port was designed for the CFD analysis, and it was modeled with 3 profile in CATIA software. It was analyzed using PUMPLINX software to compare performance.
