Worm Gear Reducers are right-angle mechanical speed reducers that utilize a threaded worm screw driving a perpendicular worm wheel to achieve high gear reduction ratios in a single compact stage. Known for their smooth and quiet operation, many high-ratio configurations offer self-locking capabilities that prevent the output shaft from driving the input shaft backward. Key hardware features typically include cast iron or aluminum housings, hardened ground steel worm shafts, bronze worm gears, integrated oil seals, and hollow or solid output shafts.
