worms and worm gears provide an effective solution for power transmission worm & worm wheel applications requiring high-ratio quickness reduction in a limited space using right angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest type of gearing.
Because the efficiency of a worm equipment drive depends upon the lead angle and quantity of starts on the worm – and because increased effectiveness is always an objective, the 
ratio ought to be kept as low as possible. To run properly, worms and worm gears used together must have the same diametral pitch and threads.
Our complete type of worms and worm gears could be ordered through the Boston Equipment Guaranteed Same Day Shipment Program for the fastest delivery possible.
