Like a ball screw, the worm in a worm gear may have a single start or multiple starts meaning that there are multiple threads, or helicies, on the worm. For a singlestart worm, each full turn (360 degrees) of the worm advances the gear by one tooth. So a gear with 24 teeth will provide a gear reduction of 24:1.

When used with Boston Gear worms, Boston Gear's worm gears provide effective power transmission in applications requiring highratio speed reduction in a limited space using right angle (90°), nonintersecting shafts. They are also the smoothest, quietest form of gearing when properly applied.

The worm, commonly used by most industrial equipment applications, is a helical thread that contains a shaft on the end. The worm is used to combine a part with a wheel that has teeth in it. These gears are used to reduce the size of the original gear. The worm gears causes the wheel to rotate, but it will not allow it to come back around.

Highperformance gears have a much higher level of efficiency compared with standard worm gears with the same level of safety against backdriving. The higher efficiency results in a significant reduction in turns while remaining below acceptable rim pull requirements. Optimizing for number of turns, rim pull, or both can provide a manual ...

A worm is meshed with a worm wheel, which looks similar to a spur gear. Wormandgear sets are a simple and compact way to achieve a high torque, low speed gear ratio. For example, helical gears are normally limited to gear ratios of less than 10:1 while wormandgear sets vary from 10:1 to 500:1.

A common worm gear reducer can deliver over 60:1 gear reduction, which is fantastic compared to other gear reducers, like a helical gear reducer that would require three stages of gearing to provide the same speed reduction. Other than that, worm gear reducers, having much more efficiency than the rest, are pretty economical as well.

Types of Gears. There are many types of gears such as spur gears, helical gears, bevel gears, worm gears, gear rack, etc. These can be broadly classified by looking at the positions of axes such as parallel shafts, intersecting shafts and nonintersecting shafts. It is necessary to accurately understand the differences among gear types to ...

Worm and worm wheel. A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear).The two elements are also called the worm screw and worm terminology is often confused by imprecise use of the term worm gear to refer to the worm, the worm wheel, or the worm drive as a unit.
