粗轧机人字齿轮座轴瓦的研磨与控制

Grinding and Control of Herringbone Gear Block Bearing bush for Roughing Mill

论述粗轧机双轴式人字齿轮轴瓦存在的检修工作量大、寿命短、齿轮容易跳动、轮齿异常磨损等缺陷。分析其产生的原因,并立足于人字齿轮座存在的刚度很大的牌坊,提出相应的解决对策,取得了较满意的结果。

The biaxial-type roughing mill herringbone gear bearing bush exists heavy overhaul workload,short life,gear easily beating,abnormal tooth wear and other defects.By analysis of their causes,and the arch based on the existence stiffness of herringbone gear block is very large,appropriate improve measure is put forward and more satisfactory results is achieved.
