轧钢机等的大齿轮,以前在齿面点蚀及磨损严重的情况下即作报废处理。我厂试验了修复再用的办法,于一九八二年将一因此报废的轧钢机齿轮用变位原理进行修复。投入使用一年多表明:这一方法在技术上是可行的,经济效益是明显的,可供有关单位参考借鉴。本文内容包括:关于疲劳问题的探讨;变位系数的选择;对所取变位系数的验算;小齿轮热装及有关事项,大齿轮加工注意事项等等。 Rolling mills and other large gear, the former in the tooth surface pitting and serious wear and tear that is scrapped. I tested the factory repair and reuse approach, in 1982 will therefore be scrapped rolling mill gear with displacement principle to repair. Put into use more than a year shows that: This method is technically feasible, economic benefits are obvious, available for reference by the relevant units. This article includes: On the fatigue problem; Selection of coefficient of variation; Check on the coefficient of variation; Pinion heat installed and related matters, Gear processing precautions and so on.
