worms and worm gears provide an effective solution for power transmission applications requiring high-ratio swiftness reduction in a restricted space using right position (90°), worm & worm wheel non-intersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest kind of gearing.

Because the efficiency of a worm gear drive depends on the lead angle and amount of starts on the worm – and because increased efficiency is always a goal, the ratio should be kept only possible. To run correctly, worms and worm gears used together must have the same diametral pitch and threads.

Our complete type of worms and worm gears can be ordered through the Boston Gear Guaranteed Same Day time Shipment System for the fastest delivery possible.
