PWS型平面二次包络蜗杆减速机详细介绍

I. Overview
    PW系列平面包络减速机(GB／T16449一1996)其蜗杆齿面是以一个平面为母面，通过相对圆周运动，包络出环面蜗杆的齿面，再从蜗杆的齿面为母线，通过相对运动包络出蜗轮的齿面，称为平面二次包络环面蜗杆副。包括：PWU、PWO、PWS型三种型式，适用于治金、矿山、起重、运输，石油，化工、建筑等行业机械设备的减速传动。
    Working conditions: The angle of intersection of the two axes is 90. I The worm speed does not exceed 1500r/rain, and the working environment temperature is 40～0℃. When the environment temperature is lower than 40℃ or higher than XNUMX℃, the lubricating oil should be heated or cooled correspondingly before starting; the worm shaft can run forward and reverse. .
