An innovative tool for the improvement of the design methodology of a trochoidal gear, which works as a part of a hydraulic pump, is introduced. For the past few years, new, specific, and demanding applications of this type of pumps have demanded to maximize efficiency and to reduce manufacturing costs by improving its two main performance indexes: volumetric characteristics and teeth contact stress. The existing methodologies and software fail to thoroughly address the design by taking into account both performance indexes. The software presented is an integrated package system, which is composed of three basic modules: design, volumetric characteristics, and contact stress module. As a result, by consecutively following each module, this new tool allows to find the better gear set for the concrete initial required design 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 indexes of a new born gerotor pump project.
