VE5 Single Axis 24V Electric Planetary Motor Worm Gear Slew Drive

Worm Gear Slew Drive​ Description

A worm gear, also known as a worm drive, is a mechanical gear system that consists of a toothed wheel, called the worm gear, meshing with a spiraling screw-like gear, called the worm. The worm gear resembles a screw thread, while the worm gear resembles a cylindrical gear with teeth that wrap around it.

The worm gear and worm have perpendicular shafts, and when the worm is rotated, it engages with the teeth of the worm gear, causing it to rotate as well. The angle of the helical teeth on the worm creates a sliding action, which results in the gear reduction between the two components. The reduction ratio is determined by the number of teeth on the worm gear and the number of threads on the worm.

Applications

Worm gears are commonly found in various machinery and equipment, including conveyor systems, packaging machinery, lifts and elevators, automotive steering mechanisms, and industrial applications where controlled motion and torque transmission are required.

Features

Some of the advantages of worm gears include:

High gear reduction: Worm gears offer high gear reduction ratios, allowing for significant speed reduction between the input and output shafts. This makes them suitable for applications where high torque and low-speed output are required.

Compact design: The compact nature of worm gears makes them ideal for applications where space is limited. Their axial arrangement results in a smaller footprint compared to other gear systems.

Self-locking feature: Worm gears possess a self-locking feature, meaning the worm gear cannot easily drive the worm. This characteristic makes worm gears useful in applications where maintaining position or preventing back-driving is necessary.

High shock load resistance: Worm gears are capable of handling high shock loads due to the large contact area between the worm and worm gear teeth. This makes them suitable for heavy-duty applications.
