随着轧钢设备的发展以及对老轧机改造的需要,要求轧钢机主传动接轴必须具备大扭矩、大倾角、高效率和安全可靠、维护简单等特点。 近年来,国外将用于汽车上的十字万向接轴用作轧钢机主传动接轴,取得了良好效果。日本中村公司研制了传递扭矩达969吨·米的重型十字万向传动接轴。1974年,日本光洋公司给新日铁室兰厂改造六机架热连轧主传动轴,采用十字万向接轴后,能连续运转40个月以上,每年可节省各种费用约一亿三千八百万日元,获得了很好的经济效益。
With the development of rolling equipment and the need for the transformation of old rolling mills, it is required that the main driving spindles of rolling mills have the characteristics of high torque, large inclination, high efficiency, safety and reliability, and simple maintenance. In recent years, foreign countries will be used for automotive universal cross shaft used as the main drive rolling mill shaft, and achieved good results. Japan’s Nakamura company developed a transmission torque of 969 tons of heavy-duty universal cross universal shaft. In 1974, Koyo Co., Ltd., Japan, renovated the main drive shaft of the hot-rolled six-stand hot rolling mill for the Nippon Steel Muroran Plant. After adopting universal cross spreader, it can operate continuously for more than 40 months, saving about 300 million yuan Thousands of millions of yen, get a very good economic returns.
