Φ400机组穿孔机用滚动接轴的改造设计

Reform design of the roll spindles of the punching machine in Φ400 tube rolling train

滚动接轴通过法兰间采用端面齿联接 ,花键副伸缩由液压机构完成 ,花键两端增设定心机构 ,且叉头为整体结构的改造设计后 ,具有联接简单 ,精度高 ,安全可靠的性能 ,能满足连续生产所需要的最低寿命。实践证明 ,此滚动接轴运转平稳 ,无冲击 ,振动小 ,寿命长 。

Under the new design that the terminal face tooth link is adopted, through a flange, to the roll spindle of punching machine in 400 tube rolling train, the spline pair flex is realized by hydraulic device, the centering device is added to the spline s two terminals and the jaw is redesigned to whole structure type, for the roll spindle, the connection becomes simple, the precision, safety and the credibility become higher, and it can meet the minimum life required by the continuous production. The practice proved that the new roll spindle has the features of smoothness, no-impact, less vibration, longer life and higher value of the use.
