... this method when m 21 > 1 (as shown in Fig. 2 ) or m 21 < 1, respectively. The extended epicycloidal gearing profile with m 21 > 1 and contact on the inner flank of the pin has previously been identified as appropriate for gerotor pumps [ 10 , 24 ] and is considered here for compressor...

...Federico Tessari; Renato Galluzzi; Nicola Amati Gerotor machines are internal gear hydraulic devices that present numerous performance benefits with respect to other topologies. For this reason, they find their application in high-efficiency mechatronic devices, such as electro-hydrostatic...

.... Editor: Prof. Philippe Velex. 14 11 2011 23 08 2012 This paper examines how the span angle design of its tooth profile affects the motion and pumping performance of a gerotor pump whose outer rotor profile is formed by an epicycloid and hypocycloid and whose inner rotor profile...

..., and relief groove effective port area module, modeling sharp rims with relief grooves in the porting plate which are related to flow performance. An analysis of the manufactured tolerance is conducted in four gear sets and results are compared and contrast. By using the bond graph model of a specific gerotor...

... rotor be designed using the closed-form equation for the inner rotor and the width correction coefficient. Thus, it is possible to design a gerotor for which there is no upper limit on the eccentricity, as in this case, undercut is prevented and there is no restriction on the tip width. We also develop...

...Chiu-Fan Hsieh Gerotor performance is influenced by sealing properties, area efficiency, contact stress, and outlet pressure. This paper uses the hypotrochoidal curve to generate the gerotor profile, and adopts the curvature difference method to assess the sealing property and predict the stress...

... parameters. An application using the GEROLAB package system methodology is carried out to obtain the best candidate, which is compared and contrasted with a gear set of a specific gerotor pump unit. As a conclusion, this new software aims to lead the designer to a better design by improving performance...
