Gear with Keyway Slot - Mechanical Component Diagram #4711 (License: Personal Use)

This vector-style image depicts a circular gear with evenly spaced external teeth and a prominent rectangular keyway cut into its hub area at the 12 o’clock position. The keyway allows precise rotational alignment with a keyed shaft, ensuring torque transmission without relative motion. The clean, monochrome rendering emphasizes functional geometry over realism, suitable for schematics or instructional materials.

Commonly used in mechanical engineering documentation, CAD libraries, educational textbooks, or online tutorials explaining gear-shaft assembly, power transmission systems, or machine design fundamentals. Matches user intent for technical diagrams, component identification, or learning about keyed connections.
