Difference between Worm Gear and Helical Gear Speed Reducers

 

Speed reducer is a useful tool that is used to amplify the machine and motor gear pair and control the output speed. The range of types of reducers depends on the intended purpose, including applications such as elevator systems or power transmission systems.

Worm Gear Reducer:-

The worm gear reducer consists of a screw (called a worm) that interlocks with a much larger gear. The gear rotates when the worm is tightened. This allows the driver to determine the speed at which the gear rotates.

Since the worm gear only works in one direction, the worm can rotate the gear, but the gear cannot turn to rotate the worm, this option provides a natural locking mechanism when it stops working.

Application of Worm Gear Reducer:-

Worm gear reducers can usually be found here:

·         Transport system

·         Elevator

·         Packaging

·         Small electric motor

·         Lift / pull (crane, winch, hoist)

·         Agitator and Mixer

·         Metal processing

Helical Gear Reducer:-

Unlike worm gears, helical gears can move in both directions. Helical gears, which are generally cut at an angle of 15 ° to 30 °, get their name from the interaction between the two gears.

It is known to work smoothly and quietly, the helical gear uses a unique design to generate a significant amount of thrust .Helical gear reducers are generally considered ideal for heavy load applications, as many teeth come into contact at the same time to distribute the load and maintain stability.

Application of Helical Gear Reducer:-

Compared to the worm gear option, the helical gear reducer has a narrow application range and is mainly used in the automotive field due to its quiet characteristics and high thrust capacity. The field of application of the helical reducer is as follows:

·         Transport system

·         Packaging

·         Lift / pull (crane, winch, hoist)

·         Agitator and Mixer
