Worm Gear

Worm gears resemble screws. A worm gear is usually meshed with an ordinary looking, disk-shaped gear, which is called the gear, wheel, or worm wheel. Worm gears are used when large gear reductions are needed. It is common for worm gears to have reductions of 20:1, and even up to 300:1 or greater. Many worm gears have an interesting property that no other gear set has: the worm can easily turn the gear, but the gear cannot turn the worm. This is because the angle on the worm is so shallow that when the gear tries to spin it, the friction between the gear and the worm holds the worm in place. This feature in the worm gear is useful for machines such as conveyor systems, in which the locking feature can act as a brake for the conveyor when the motor is not turning. There are three types of worm gears. The first are non-throated worm gears. An enveloping (hourglass) worm has one or more teeth and increases in diameter from its middle portion toward both ends and is the second type of worm gear. And the third worm gear is double-enveloping worm gearing comprises enveloping worms mated with fully enveloping worm gears. It is also known as globoidal worm gearing. These are made available by Pinak industries without compromising on any of the above listed aspects at market leading prices.

Pinak Industries was incorporated in the year 1986. They specialize in the design and manufacturing of distinct categories of gears. These gears are manufactured with stringent quality norms followed globally.
