摘要: 文中简述了多种设计方案的对比和两级齿轮传动重叠系数的匹配。选择了齿轮法面模数m n=20mn的方案和采用了分析式的基本齿形。核算了强度的安全系数。运行了六年多,已轧制钢坯超过一千万吨,为原渐开线齿轮减速器的三倍多。实践证明该减速器承载能力高,运转平稳,噪声低,效率高。已取得了很大的经济效益。现在该机仍在正常使用。

Abstract: The present achievement in scientific research provides a new way for increasing the load-bearing capacity of large gear drives. A brief comparison of several existing designs and the matching of two-stage gearing drive overlapping factors are given. The design with normal module Mn= 20mm,and a stepped basic rack profiles are adopted. Safety coefficients of the strength calculation are also given in the paper. By the end of February 1988, this machine has been operating for more than six years. Tens of million tons ofs feel billets were successfully rolled using the new reduction gear. The outputs are more than three times of that produced by a reduction gear with involute profiles. It fully proves that the machine is higher in Load-bearing capacity, easier to manufacture, and guarantees more stable operation, lower noise, higher efficiency, than the reduction gear with involute profiles at the same operation condition. Bearing vibration also satisfies the specification as dictated by the standards of ISO, IS and VDI. Huge economic benefits have been gained since its installation, and this novel reduction gear is still functioning normally.
