This project presents a complete 3D model of an external gear pump, fully designed and assembled in Sieme NX assembly includes all internal components required for an educational, mechanical and kinematic undetanding of how this type of hydraulic pump model features:Parametric gear pair (module 2.5, Z=12, 30° pressure angle)Correct gear engagement and alignmentShafts with tapered fit and Woodruff keys (DIN 6888)Full housing, front cover, rear cover and internal geometrySealing regio and functional clearancesComplete exploded viewMotion study using NX Motion (Joints and Gear Coupler)All parts modeled from scratch in Sieme NXTypical applicatio of external gear pumps include hydraulic systems in agricultural machinery, cotruction equipment, industrial power units and fluid tramission model is intended for:Students learning CAD and mechanical designEnginee studying hydraulic pump kinematicsAnyone who wants a clean and structured NX assembly referenceEducational and demotration purposesHonorable Mention:The initial ipiration for this project came from a model presented on the YouTube channel @ on that reference, the tramission and retention elements of the pump were redesigned to achieve a clearer and more technically coistent free to download, study, explode the assembly, run the motion, and modify the d by Felipe Borba.
