Worm Wheel Gears

Worm Wheel Gears are a type of gear drive in which a screw-shaped worm meshes with a flat, toothed wheel. The worm has a higher reduction ratio than a spur gear, making it an efficient and quiet way to reduce speed. Worm Wheel Gears are often used in automotive transmissions, conveyor systems, and other applications where a large speed reduction is needed. They are also self-locking, meaning that they can hold a load without slipping.

Importance and Types of Worm Wheel Gears

Worm wheel gears are important in many types of machinery, as they provide a large gear reduction in a small package. They are especially useful when the shafts are parallel or when the gear ratio must be greater than 10:1. Worm wheel gears are also used in variable speed drives, as their design allows for smooth and quiet operation. 

Types

There are two main types of worm wheel gears: the single thread and the double thread. Single-thread worm wheels have a single thread that wraps around the circumference of the gear. These are used for applications requiring low speed and high torque. Double-thread worm wheels have two threads that wrap around the circumference of the gear. These are used for applications requiring higher speed and lower torque. Both types of worm wheels can be made with either a right-hand or a left-hand thread.
