摘　　要：分析了3500mm中厚板四辊轧机机架辊损坏的原因,并对其齿轮的结构参数进行了校核。经过分析发现:齿轮箱内部结构不合理是导致机架辊损坏的主要原因。通过改进箱体的结构,使其工作环境得到了改善,降低了维修和轧制的成本。The damage cause of framework roller of a 3 500 mm 4-h plate mill was analyzed, and the structure parameters of gear- box was checked. The main reason of this roller damage was turned out to be unreasonable gearbox structure. The solution to im- prove the gearbox structure was put into practice, then the working condition of framework roller was improved and maintenance cost was decreased.
