Large Diameter Nylon Plastic Injection Molded Spur Worm Gear
Worm gear
Worm gear mechanisms are often used to transmit motion and power
between two staggered shafts. The worm wheel and the worm are
equivalent to the gear and the rack in their mid-plane, and the
worm is similar in shape to the screw. If you want to get a larger
gear reduction ratio, you need to use a worm gear. The gear
reduction ratio of a worm gear is generally 20:1, sometimes as high
as 300:1 or more.
Features of worm gears
1. A large transmission ratio can be obtained, which is more
compact than the staggered shaft helical gear mechanism.
2. There is a line contact between the meshing tooth surfaces of
the two wheels, and its bearing capacity is much higher than that
of the staggered shaft helical gear mechanism.
3. The worm drive is equivalent to a screw drive, which is a
multi-tooth meshing drive, so the drive is stable and the noise is
small.
4. It is self-locking. When the lead angle of the worm is less than
the equivalent friction angle between the meshing gear teeth, the
mechanism has self-locking properties and can achieve reverse
self-locking, that is, only the worm can drive the worm, but not
the worm. Such as the self-locking worm mechanism used in its heavy
machinery, its reverse self-locking can play a role in safety
protection.
