worms and worm gears provide a highly effective solution for power transmission applications requiring high-ratio velocity reduction in a limited space using right position (90°), non-intersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest kind of worm & worm wheel gearing.
Because the efficiency of a worm gear drive depends upon the lead angle and number of begins on the worm – and because increased performance is always an objective, the ratio should be kept only possible. To run correctly, worms and worm gears utilized together must have the same diametral pitch and threads.
