球面蜗轮付,由于啮合齿数多,高压动力油膜形成好,以及具有双接触线等特点,因而具有承载能力大、体积小、寿命长等优点,国內外已广泛用于重型、矿山和冶金机械等低速重载传动中。我厂生产的JH2—14型回柱绞车,所用的中心距为300毫米的球面蜗轮付减速器,过去由于沿用苏联的落后的设计和制造方法,以致该减速器质量长期不过关,经常发生拉毛、胶合、发热、冒烟等现象,机械效率极低,电流超出额定指标30～40安培。针对这一情
Spherical worm gear, due to the meshing teeth, high-pressure power oil film formation, and with double contact lines and other characteristics, which has a bearing capacity, small size, long life, etc., both at home and abroad have been widely used in heavy mining, metallurgical machinery and so on Low-speed heavy-duty transmission. I produced the factory JH2-14-type column winch, the center distance of 300 mm spherical worm reducer, the past due to the Soviet Union’s backward design and manufacturing methods, so that the quality of the gear unit for a long time, often occur in the hair , Gluing, fever, smoke and other phenomena, the mechanical efficiency is very low, the current exceeds the rated target of 30 to 40 amps. Against this situation
