worms and worm gears provide an effective answer for power
transmission applications requiring high-ratio speed reduction
in a limited space using right angle (90°), non-intersecting
shafts. When properly applied, worms and worm gears provide
the smoothest, quietest form of gearing.
Because the efficiency of a worm gear drive depends on
the lead angle and number of starts on the worm - and because
increased efficiency is always a goal, the ratio should
be kept as low as possible. To run properly, worms and
worm gears used together must have the same diametral pitch
