Worm gear sets may be either single- or double-enveloping. In a single-enveloping set, the worm wheel is cut into a concave surface, thus partially enclosing the worm when meshed. The double-enveloping worm gear is similar to the single-enveloping gear; however, the worm envelopes the worm gear....

Worms and Wheels Manufacturer A worm drive is a gear arrangement in which a worm, a gear in the form of a screw, mates with a worm gear, smaller in appearance than a spur gear and also called a worm wheel. Like other gear arrangements, a worm drive can reduce rotational speed or enable higher...

Dual lead worm gears, as their name suggests, are constructed with two leads. One flank of the worm thread and its mating sides of the wheel teeth are manufactured with one lead, and the other flank and its mating wheel teeth to a slightly different lead. As far as the worm is concerned this had...

The lowest cost and shortest delivery schedules are normally achieved through the use of standard worm and gear sets. In addition to using standard shaft center distances, ratios, and bearing mounting parts, designs should include standard bores, flanges, and bolt circles where possible. Since...
