Worm screw liftTransmission characteristics: The transmission is composed of a worm and a worm gear, which is used to transmit the motion and power between the staggered shafts. Usually, the staggered angle of the two shafts is 90°. In the general worm drive, the worm is used as the driving part.Worm screw liftThe cross section that passes through the worm axis and is perpendicular to the worm wheel axis in the meshing transmission.
1. The meshing of the worm and the worm gear in the main section is the meshing of the involute rack and the gear.
2. The involute rack and pinion of the worm gear and screw lift are meshed, but regardless of the shape of the meshing tooth profile, the worm and worm gear transmission is stable, the vibration noise is small, and the bearing capacity is high.
3. There are basic parameters in the worm gear lifter: modulus and pressure angle.
4. The worm and worm gear drive can obtain a larger transmission ratio.Because the worm has fewer teeth, the worm gear can have many teeth.
