Exploring The Basics Of Worm Gear Motor

Worm gear motor is known mainly for its compact design and its ability to generate excellent torque in spite of its size. But what is the basic mechanism of this type of gear motor? What are some different ways in which a shaft is attached to a worm gear motor? Lastly, what are some of its other advantages? This blog will answer all these questions in detail.

What Are Worm Gears?

A worm gear assembly used in a gear motor has two basic components: a threaded screw and a modified spur gear whose teeth are slightly curved. The teeth of the gear fit snugly into the threaded screws enabling appropriate power transfer.

There are three main shaft configurations for this type of gear motor:

- Right angle gearing
- Left angle gearing
- Hollow shaft gearing

Of the three, the right angle gearing is the most prominent. This is why worm gears are also known as right-angle gear motors in some cases, although there are other types of gearing that also fit this description. Right-angle gearing is primarily used in applications where there is a need for rapid speed reduction or rapid torque increase in a very confined space.

Advantages Of Worm Gear Motors  

Now, what sets worm gear motors apart from other simpler types of gear motors? Here are two primary differences:

Huge Reduction Ratio: The reduction ratio of worm gear motors is quite impressive. This means with a small turn of the worm gear, the main gear will rotate far more. Therefore, worm gear motors can single-handedly achieve the output of several regular gears.

Rigidity To Reversing: Worm gear motors can’t be reversed. Hence, they only travel in one direction. This eliminates the need for a backstop, which has to be added to other gear motors to prevent reversal, thereby increasing the components. This is a luxury not available in compact spaces. This is why worm gear motors are further justified in constrained spaces.
