Product details

PWS plane envelopetorusworm reducer(GB/T16449-1996) Its worm gear surface is formed by a plane as the mother surface, enveloping the tooth surface of the toroidal worm gear through relative circular motion, and then enveloping the tooth surface of the worm gear through relative motion using the tooth surface of the worm gear as the generatrix, which is calledPlanar enveloping toroidal wormVice-. 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.
