Worm Gear Reducers

A worm gear reducer is a type of reduction gear that is used to convert high motor speed input into lower speed output while also maintaining high torque. The worm producer consists of a gear in the form of a screw meshed into the machine which outputs in the right angle orientation. The worm gear gearbox is mostly made of bronze with steel or stainless steel worm. The size of the worm gear reducer is very small and sleek compared to other gear reducers, which makes it very handy for rated motor speed and space problems.

Uses of Worm Gear Reducers

The worm gear reducers are applied in fields like tuning instruments, elevators, escalators, conveyor belts, medical equipment, power transmission systems, and security gates. Worm gears are commonly used in lifts and elevators to control the speed of a load so that it does not free-fall. The efficiency of a worm gear reducer is generally much higher than that of a helical one. A high-efficiency helical gearbox will cost $300 more than a standard worm gearbox. While worm gears are more efficient for machines with lower horsepower, they are also less efficient for high-torque applications. The price difference between a helical gearbox and a worm gear reducer can be offset by the amount of power dollars they store.

Types of Worm Gear Reducers

Here are several common types including aluminum worm gearbox, cast iron worm reducer and stainless steel worm reducer. While the efficiency of each type depends on its size, all three have the same purpose: to reduce the speed of a machine. While the worm gear is often used as a speed reducer in low-speed applications, it can also be used as a secondary braking device in high-speed machinery.

Worm Gear Reducers FAQs

What is the worm gear reducer used for?
A worm gear (or worm drive) is a specific gear composition in which a screw (worm) meshes with a gear/wheel similar to a spur gear. The set-up allows the user to determine the rotational speed and also allows for a higher torque to be transmitted.

How does a worm gear work?
An electric motor or engine applies rotational power via the worm. The worm rotates against the wheel, and the screw face pushes on the teeth of the wheel. The wheel is pushed against the load.

Can a worm gear go in both directions?
Worm drives can go either direction, but they need to be designed for it. As you can imagine, turning the worm shaft under load will create a thrust along the axis of the screw. However, if you reverse the direction, the direction of thrust will also reverse.

How do you find the gear ratio of a worm gear?
Number of Threads in Worms
The number of threads in a worm is the number of teeth in a worm. The speed transmission ratio of a worm and worm gear set is obtained by dividing the number of teeth of the worm gear by the number of threads of the worm.

These are further available in different ratios. The RV reducers are available in the ratios of 5:1 to 100:1. The worm gearboxes are also classified according to their uses and structure. Some of them are – Shaft to bore, flange mount, NEMA flange, miniature, high-ratio reduction, compact, and molded glass-filled housing. You can also get it modified according to particular needs.

Benefits of Worm Gear Reducers

The primary benefit of the small worm drive gearbox is that it produces an output of ninety degrees to the input with higher torque and lower speed. In addition to the benefits of high-speed reduction and torque multiplication, the worm gearbox also provides for shock absorption, quiet operation, smaller size, and the adjustable mounting position. This makes the worm gear reducer the best quality reducer for heavy applications.
