Product details
PWU平面包络环面蜗杆减速机
PW typePlanar enveloping toroidal wormThe worm gear surface of the reducer (GB/T16449-1996) is based on a plane as the mother surface, and through relative circular motion, it envelops the tooth surface of the toroidal worm gear. Then, using the tooth surface of the worm gear as the generatrix, it envelops the tooth surface of the worm gear through relative motion, which is called a planeEnveloping toroidal worm gearVice-. It includes three types: PWU, PWO, and PWS, suitable for deceleration transmission of mechanical equipment in industries such as metallurgy, mining, lifting, transportation, petroleum, chemical, and construction.
