spur gear

I designed a parametric 3D model of a spur gear using PTC Creo Parametric, focusing on accurate gear tooth geometry and mechanical functionality for power transmission applications. The model was created by first defining the gear base profile, pitch circle, and central bore, followed by the development of a single gear tooth profile using sketching and extrusion features. After generating the initial tooth geometry, I used the circular pattern feature to replicate the tooth around the gear axis, ensuring uniform spacing and precise alignment of all teeth along the pitch circle. This approach ensured that the gear maintains correct tooth distribution and rotational symmetry, which are essential for smooth meshing with mating gears. The design includes important structural features such as the hub, inner bore for shaft mounting, and the outer toothed rim. Proper dimensional control was maintained to ensure that the gear could be used in mechanical power transmission systems, such as gearboxes, machine drives, and automated equipment. The modeling process also involved feature tree management, parametric sketching, extrusion operations, and pattern generation, allowing the gear geometry to be easily modified by changing key parameters such as number of teeth, module, and gear diameter. This project demonstrates proficiency in mechanical component design, parametric modeling, and CAD-based gear geometry development using PTC Creo.
