Abstract
This work is an effort to find the parallelism between the volumetric efficiency of a Gerotor, and its inherent design parameters: number of teeth, tooth profile, outer dimensions of diameter and thickness, and the input power (torque and speed). The preliminary relations are derived from the software simulation of a range of Gerotor models with varying aforementioned parameters. These results are augmented by a previously proposed method of theoretically estimating the displacement of a Gerotor. Then, these results are validated and revised by practical results from three different Gerotors with epitrochoidal and its conjugate profiles, which are used in automotive applications like engines and transmissions. These relations can be used for choosing parameters yielding the maximum efficiency in specific environments: the packaging space, the input available, and the output required. Finally, an attempt has been made to develop a theoretical formula of the efficiency of a Gerotor in light of the above parameters. According to these results, a prototype Gerotor is proposed and will be validated for its performance.
