Helical gear

A single cylindrical helical gear shown in slight perspective or front three-quarter view so the helix direction is clearly visible. The gear has a broad, uniformly thick, solid disk-like steel-gray metallic body with smooth machined circular side faces, crisp tooth edges, a central round bore, and a subtle machined hub. Evenly spaced external teeth are cut at a clear diagonal helix angle across the face width, with slanted tooth traces and angled tooth flanks wrapping around the outer rim in a continuous twisted spiral pattern, clearly distinguishing it from a spur gear.
