Definition - A Top Shaft is a primary rotating shaft positioned at the upper part of a machine or mechanism that transmits power and motion to other components. Its purpose is to receive drive from a motor or input source and distribute rotation to gears, pulleys, or secondary shafts. Top shafts are commonly used in gearboxes, textile machinery, conveyors, and other industrial equipment where power needs to be transmitted from an upper drive position.
