Introduction about Worm gear & Helical gear
Worm gears are able to withstand high shock loads, low in noise level and maintenance-free but are less efficient than other
gear types. Worm gears can be used in right angle configuration. The worm gearbox configuration allows the worm to turn the
gear with ease; however, the gear cannot turn the worm.The prevention of the gear to move the worm can be used as a braking
system. When the worm gearbox is not active, it is held in a locked position.
Worm gears are typically constructed of aluminum, stainless steel and cast iron.The material used varies depending on the manufacturer.
Helical gears are cut at angles which allow for gradual contact between each of the helical gear teeth. This type of innovation
provides for a smooth and quiet operation. Gearboxes using helical gears are applicable in high horsepower and efficient
Helical gears are typically constructed from cast iron, aluminum allow or iron material but may vary depending on the
