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.
