worms and worm gears provide a highly effective solution for power transmission applications requiring high-ratio rate reduction in a restricted space using right position (90°), nonintersecting 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 
begins 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 will need to have the same diametral pitch and threads.
