Worm gear and structure are often used to transmit the motion and power between two staggered shafts. Worm gear and worm are equivalent to gear and rack in the median plane, and the shape of the worm is similar to that of the screw.
Characteristics of the worm gear and worm shaft
1. A large transmission ratio, which is more compact than the staggered helical gear mechanism, can be obtained.
2. The meshing tooth surfaces of two wheels are in line contact, and their bearing capacity is much higher than that of the staggered helical gear mechanism.
3. Worm transmission is equivalent to spiral transmission, a multi-tooth meshing transmission, so the transmission is stable, and the noise is very low.
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 is self-locking and can achieve reverse self-locking; that is, only the worm can drive the worm, but not the worm. For example, the reverse self-locking of the self-locking worm mechanism used in hoisting machinery can play a role in safety protection.
5. The axial force of the worm is large.
Worm gear and mechanism are often used when two shafts are staggered; the transmission ratio is significant, and transmission power is small or intermittent.
