worms and worm gears provide an effective solution for power transmitting applications requiring high-ratio velocity reduction in a restricted space using right angle (90°), nonintersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest type of gearing.

Because the effectiveness of a worm equipment drive depends upon the lead angle and number of starts on the worm – and because increased performance is always a goal, the ratio should be kept as low as worm & worm wheel possible. To run correctly, worms and worm gears utilized 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 Time Shipment System for the fastest delivery possible.
