齿轮机座是轧钢机的重要传动设备,共质量好坏、寿命长短与产量和经济效益密切相关。据有关部门统计,我国冶金企业从1958年至1981年间,因齿轮机座发生事故影响轧钢生产共1900多个小时,占轧钢机械设备总事故的15％。我厂三辊劳特式精轧机的齿轮机座在设备改造前的1976、1977两年中,两次发生重大事故,共停产319小时,经济损失在120万元以上。目前,国产轧钢机齿 Gear base is an important transmission equipment rolling mill, the total quality is good or bad, the length of life and yield and economic benefits are closely related. According to statistics from related departments, from 1958 to 1981, China’s metallurgical enterprises affected more than 1,900 hours of rolling production due to the accident of gear base, accounting for 15% of the total accident of rolling machinery and equipment. In the two years of 1976 and 1977 before the transformation of the equipment, the gear frame of the three-roller Loughing finishing mill of our factory had a total of 319 hours of suspension and a total economic loss of over 1.2 million yuan. At present, domestic rolling mill teeth
