Interlocking Gears Illustration - Mechanical Engineering Diagram #3259211 (License: Personal Use)

This black-and-white engraved-style illustration depicts two spur gears in direct mesh: a large gear with radial spokes and a central hub, and a smaller gear with a solid hub and concentric rings. The teeth are uniformly shaped and precisely interlocked, emphasizing mechanical power transfer. Fine linework conveys depth, texture, and functional realism typical of 19th- to early-20th-century engineering manuals.

Commonly used in educational materials on mechanics, physics textbooks, industrial design blogs, or historical engineering archives; serves users seeking visual explanations of gear systems, torque transmission, or retro technical aesthetics.
