WH圆弧齿圆柱蜗杆减速机，包括WHT（通用型），WHX（蜗杆在蜗轮之下），WHS（蜗杆在蜗轮之上）和WHC（蜗杆在蜗轮之侧）四个系列，主要用于冶金、矿山起重、运输、化工、建筑等各种机器设备的减速传动,工作环境温度为0℃~45℃,高速轴可正反向运输,蜗杆转数≤1500r/min。
WHT型蜗轮蜗杆减速机是采用轴截面为圆弧形的圆柱蜗杆，蜗轮齿形与蜗杆相共轭的圆弧，由于蜗轮与蜗杆是凸凹啮合，在啮合区的绝大部分综合曲率半径大，因而降低了齿面应力，增加了齿面强度，提高 了承载能力，同时该齿形合理地减薄了蜗杆齿厚，增加了蜗轮齿板厚，因而蜗轮齿板抗弯强度增大，传递能力增大，还有接触线与圆周速度夹角绝大部分在40°～90°之间，容易形成液体润滑，齿面间摩擦系数小，所以效率高，温度底。该产品符合JB2318-79标准）WHT－蜗杆可以在蜗轮之下、之上、之侧的通用型圆弧齿圆柱蜗杆减速器。适用于冶金、矿山、起重、运输、化工、等建筑各种机械设备的减速传动。本系列减速器输入功率范围在0.4～163KW之间；输出扭矩在11～2600kgf·m之间，输入轴转数一般不大于1500转/分；高速轴可正反两向运转；工作环境温度为-40℃～45℃；当工作环境温度低于0℃时，启动前润滑油_加温到0℃以上。WHT型的中心距有四种即：42、65、80、100，速比有：8、10、12.5、16、20、25、35、40、50九种，装配形式有八种。
