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.
