Several types of power transmission systems use worm gears. They include conveyor belts, elevators, security gates, and medical testing equipment. They are also used in farming, automotive, and shipbuilding.

Worm gears are also used as secondary braking devices. They have a low vibration, and are relatively quiet. They are durable, and improve with prolonged use. They are also known for their smooth operation. However, they are not the most efficient type of gear. They are difficult to lubricate, and need special lubricants. They also have limited horsepower ratings. These low ratings can lead to lower long-term efficiency ratings.

A worm gear speed reducer is a type of speed reducer that uses a worm wheel. The worm wheel is the part of the gear that applies the load to the drive shaft. The worm wheel is designed to rotate in accordance with the designed reduction ratio. This reduces the input rotational speed, and increases the output torque.

Worm gear speed reducers are very compact. They can be used on solid or hollow output shafts. They are also very flexible. They can be used in many applications, including automobile manufacturing, power transmission, farming, and medical testing. They can also be used in mobile applications. Besides offering improved torque, worm gear speed reducers are also space-saving.

Worm gears offer a high reduction ratio. Their design offers excellent shock-loading qualities. However, they are not reversible. This is due to the friction between the worm wheel and the wheel. Because of this, it is impossible to reverse the direction of the power. In addition, worm gears are difficult to lubricate, and require specialized lubricants.

Besides being durable, worm gears offer some advantages over standard gears. The most notable advantage is that it is possible to achieve high reduction ratios without a lot of work. Unlike conventional gearsets, which require several reductions to achieve the same reduction level, a worm gear requires only one reduction.

There are three major types of worm gears. The two main types are internal helical gears and external helical gears. The internal helical gear needs the same hand for both parts. However, the external helical gears need to have opposite hands.

Worm gears are usually lubricated with a mineral-based compounded gear oil. This lubricant is usually high viscosity. This lubricant requires a slow operating pump, and requires a large surface area filter. A combination of natural or synthetic fatty additives results in additional protection from metal-to-metal contact.

In addition, worm gears offer a high torque multiplier, which is beneficial in increasing the output torque. Because worm gears offer a high reduction ratio, they are also used in power transmission applications. They are also used in certain industrial applications, including lifts, medical testing equipment, and tuning instruments. The right angle worm gear is the most common type of worm gear used for speed reduction. This type of worm gear is highly durable, and is tolerant of shock loads.

The right angle worm gear has several benefits over other types of worm gears. It is cost-effective, durable, and versatile.
