PW series plane double enveloping toroidal worm reducer (GB/T16449-1996), the worm tooth surface is based on a plane as the mother surface, through relative circular motion, the tooth surface of the toroidal worm is enveloped, and then from the worm The tooth surface is the generatrix, which envelops the tooth surface of the worm wheel through relative motion, which is called a plane double enveloping toroidal worm pair.Including PWU, PWO, PWS three forms, suitable for the reduction transmission of machinery and equipment in metallurgy, mining, lifting, transportation, construction, petroleum, chemical and other industries.

    工作条件：两轴交角为90°；蜗杆转速不超过1500r/min;工作环境温度为0-40℃，当环境温度低于0℃或高于40℃时，启动前润滑油要相应加热或冷却；蜗杆轴可正反向运转。
