四机架冷连轧机6#张力辊齿轮联轴节故障分析与改进

Fault Analysis of Gear Shaft Coupling for Tensile Roll No.6 at the 4 stand cold Rolling Mill Machine

本文对冷轧厂四机架冷连轧机6#张力辊齿轮联轴节多次出现滚齿故障进行研究分析,并根据工况对原设计进行了改进和强度校核,改进后使用寿命大大地提高了。

The paper analyses the hobbing faults frequently occurred on the gear shaft coupling of tensile roll No.6 at the 4 stand cold rolling mill machine,and makes improvement and strength check based on ordinary dsign.As a result,it greatly increases the operating life of coupling.
