Purchasing Resources for Worm Gears

Worm Gears

Choose worm gears for high-ratio speed reduction applications
By Ydalia Tolentino Worm gears are arrangements of gear sets that consist of worms that mesh or mate with worm wheels. In worm gear drives, the worm drives the worm wheel. Worm gears can be good choices for power transmission applications that need high- ratio speed reduction in minimal spaces utilizing 90 degrees, non-intersecting shafts. These gears can also multiply torque. Some examples of worm gears usage in applications include conveyors and pallet loaders. In worm gear design, some important specifications are diametral pitch, pressure angle, number of teeth, material choice and direction of tooth curve (right or left).

Manufacturers can offer different types of worm gear products such as a micro worm gear or a worm gear robotics kit. Material options for worm wheel gears include various metals and plastics. Some metal options are bronze, aluminum and steel, while some plastic choices are nylon, acetal and Delrin.

When you require worm gears for specific applications, some options to consider are:

1. Choose worm gear manufacturers that have a good selection of products.

2. Find a manufacturer that provides custom worm gears.

3. Search online for vendors of worm gears.
