Reduction Ratio

Gear reducers utilize double- or triple-reduction gearing; Fig. 3.112 shows a schematic of the most popular double-reduction unit. It contains three shafts: the high-speed input shaft, an intermediate shaft, and a slow-speed shaft. The high-speed shaft is driven by the prime mover through a V-belt sheave, and the slow-speed shaft drives the crank arms of the pumping unit.
