轧立式轧机减速机螺旋伞齿轮断齿原因分析

Analysis on reason of roll vertical rolling mill moderating machine spiral bevel wheel's broken teeth

湘钢一高速线材粗中轧立式机架减速机齿轮箱,第一级传动螺旋伞齿轮轮齿断裂。文章对2V、4V螺旋伞齿轮计算分析,找出减速机在结构上的不合理及制造安装缺陷,提出改进意见。

A high speed line material vertical rolling mill framework moderating machine gearbox of Hunan steel Co., Ltd, the gear teeth of the first transmission spiral bevel wheel were broken. The author analyses to 2V, 4V spiral bevel gear computational, finds out unreasonable structure and shortcoming of installing in moderate plane, puts forward the suggestion of improving.
