Double-enveloping worm gear sets have both members throated and wrapped around each other Crossed axis helical gears are not throated and are sometimes referred to as non-enveloping worm gear sets The worm teeth may have a variety of forms and are not standardized in the way that parallel axis gearing is but the worm wheel must have

There are two types of worm and wheel gear sets depending on whether the teeth of one or both wrap around each other • • Single enveloping worm and wheel gear sets see Figure 11 4 and Double enveloping worm and wheel gear sets see Figure 11 5 442 Chapter 11 Pitch diameter d w Helix Worm Root diameter Pitch cylinder Helix angle ψ w

Worm gears possess a unique feature: when connected to the drive motor they can easily turn the gear but the gear finds it difficult to turn the worm This happens because the angle on the worm is very shallow and when the gear connected to the FCE tries to rotate it the frictional force between the gear and the worm does not allow any worm
