3d Gear Generator May 2026

Author: [Your Name/Affiliation] Date: [Current Date] Abstract The design of mechanical gears requires precise mathematical calculations involving module, pressure angle, and tooth profile to ensure proper meshing. Manual 3D modeling of gears is tedious and error-prone. This paper presents the development of a 3D Gear Generator —a software tool that automates the creation of ready-to-print 3D gear models (Spur, Helical, and Herringbone) using parametric inputs. The system utilizes the Involute Curve equation to generate accurate tooth profiles and exports standard file formats (STL/STEP) for additive manufacturing. Validation through 3D printing shows that the generated gears exhibit a deviation of less than 0.1 mm from theoretical specifications. 1. Introduction Gears are fundamental to power transmission in machinery. While traditional subtractive manufacturing (hobbing, milling) remains standard, Additive Manufacturing (AM) has enabled rapid prototyping of custom gears. However, a bottleneck persists: the gap between gear design theory (DIN 3977, AGMA) and CAD software. Most engineers manually sketch or import tooth profiles, a process lacking repeatability.
