Worm reducers are gearboxes that reduce the speed of a rotating shaft. They can be used in a variety of applications and industries. They have a high rate of efficiency and can be installed in tight spaces. Worm reducers can be up to 1.5 times more efficient than two-stage gearboxes. They are available with a variety of features, including a wide range of gear ratios and torque limits.

Worm gears have a relatively small number of moving parts compared to other types of gears. Because of this, they can be more reliable and can handle heavy loads. Worm gears are also widely used in lifts and elevators. Worm gears are soft in nature, which facilitates simple shock absorption and helps reduce failure rates. This is an important consideration for heavy-duty applications such as rock crushers.

Worm gears should be lubricated properly to avoid premature failure. Worm gear manufacturers furnish approved lists of lubricants. These lubricants have been thoroughly tested and the manufacturer knows which ones are best for the reducer. Using unapproved gear oil can cause the reducer to fail. The right lubricant for a specific application is dependent on loads, speeds, duty cycle, and operating temperature.

Worm gears can reduce a torque of up to ten times their initial value. However, this high reduction ratio requires many revolutions of the input gear. This can lead to an increased amount of friction. Worm reducers have a high efficiency factor, but they are not as efficient as hypoid gears. Hypoid gears are usually more efficient, but they are also more expensive than worm gears.

Worm gear reducers are used in various types of power transmission systems. For example, they are used in elevators, security gates, and medical testing equipment. They are also used in tuning instruments. In fact, many of these devices have a high torque output multiplier. You can also find worm reducers in conveyor belts and elevators.

A worm gear reducer is a gearbox with a large worm gear driving a helical gear-equipped output shaft. This gear provides a high mechanical advantage for a small size, and worm gears have excellent shock-loading properties. Moreover, worm gears are space-saving, which is a great benefit when space is limited.

The KHK company has two types of worm reducers, the SW2-R1 and the SW2-R2. The SW2-R1 has one thread while the SW2-R2 has two threads. The threads on the worm gears differ in their advancing angles. If you are planning to install a worm gear reducer on your machine, it would be best to consider a hardened gear with a longer lifespan.
