|When used with
worm gears, Boston Gear worms provide an effective answer
for power transmission applications requiring high ratio
speed reduction in a limited space using right angle (90°),
non-intersecting shafts. Manufactured from acetal, nylon,
and hardened and unhardened steel, they offer the smoothest,
quietest form of gearing when properly applied.
Because the efficiency of a worm gear drive depends on
the lead angle and number of starts on the worm, it's important
to keep the ratio as low as possible. It is equally important
that worms and worm gears used together must have the same
diametral pitch and threads.
