An internal gear is a cylindrical gear with its teeth located on the inner surface of its rim. It meshes with an external gear, rotating in the same direction, which enables compact designs. Internal gears are widely used in planetary gear systems, industrial clutches, automotive transmissions, and aerospace drives, offering high reduction ratios, high torque capacity, and precise power transmission.
