大模数(m10)圆弧面蜗杆,通常用于低速重载机械设备中,其齿形在轴向截面内为直线,蜗杆直径及螺旋角是变化的。这种蜗杆通常在大型滚齿机上加工。 图1所示为苏制九吨高压水泵中的圆弧面蜗杆,其分度圆导程为 36π,头数 K=2,工作转速为 980 r/min。我们附加一套装置可在车床上加工 Large modulus (m10) arc worm, usually used in low-speed heavy-duty machinery and equipment, its profile in the axial cross-section of a straight line, the worm diameter and helix angle is changing. The worm is usually machined on a large gear hobbing machine. Figure 1 shows a nine-ton high-pressure water pump in the Soviet Union arc worm with a pitch of 36π, the first number K = 2 and a working speed of 980 r / min. We add a set of devices can be processed in the lathe
