Shanghai Metal Corporation is a professional manufacturer and supplier of Worm Gear and Worm Shaft with high quality and reasonable price.

Worm gears, as small yet capable of achieving high speed ratios, are commonly used in reduction devices. In addition, according to the installation position of the gear shaft, worm gears and helical gears with staggered shafts belong to the category of staggered shafts.

A gear with threads cut on a cylindrical material is called a worm gear, a gear that meshes with it at a 90 degree axis angle is called a worm wheel, and when used in combination, it is called a worm gear pair. The application history of worm gears is long, according to Archimedes' account, they existed around 250 BC.

Worm gears can be roughly divided into two categories. One type is a cylindrical worm gear and a worm wheel that meshes with it, known as a cylindrical worm gear pair. Another type is the drum shaped worm gear and the worm wheel that meshes with it, known as the drum shaped worm gear pair.

Worm gears have a smaller volume than spur gears (cylindrical gears/spur gears) and can achieve a larger reduction ratio, making them more suitable for narrow spaces. The reduction ratio is determined by the number of teeth on the worm gear and the number of teeth on the worm wheel. The maximum reduction ratio of the worm gear is 1/120.
