Abstract
A miniaturized motor includes a DC motor, a worm, a pinion gear, a worm gear, at least one cluster gear, an output gear and an output shaft. The gears form a gear train extending from the DC motor to the output shaft. A boss stabilizes the pinion gear by extending downwardly from inside the cover. Acoustical chambers packed with grease suppress noise generated by the gear train. A PC board is also provided on the cover to energize the DC motor. The output shaft may drive either a product mover for beverage cans inside a vending machine or another type of electromechanical unit requiring the application of high torque in a small space. A cradle bearing inside a cover holds a hub of the worm and prevents the worm from bending, thus assuring a good mesh of the worm with the pinion gear. A nest encapsulates the worm, the pinion gear and the worm gear to ensure protection and structural integrity of the miniaturized motor within the small space.
