Worm Gearbox With Output Shaft

A gearbox designed using a worm and worm wheel is considerably smaller than one made from plain spur gears and has its drive axes at 90° to each other. With a single start worm, for each 360° turn of the worm, the worm-wheel advances only one tooth of the gear wheel. With spur gears, a gear of 12 teeth must match with a 240 tooth gear to achieve the same 20:1 ratio.
There are three different types of gears that can be used in a worm drive.
The first is a non-throated worm gear. It doesn't have a throat, or groove machined around the circumference of either the worm or worm wheel.
The second is single-throated worm gear, in which the worm wheel is throated.
The final type is double-throated worm gear, which has both gears throated. This type of gearing can support the highest loading.
