高刚度短应力线轧机, 承载能力大, 设备结构紧凑, 重量轻; 整机架换辊, 换辊时间短; 轧辊轴承采用四列短圆柱轴承(用以承受径向力)及推力辊子轴承或四点角接触轴承(用以承受轴向力)。
With high rigidity and short stress line, the rolling mill has a large bearing capacity, a compact structure and a light weight; roller replacement can be performed within a short period of time for the whole frame; roller bearings shall be four-row short cylindrical roller bearing (to absorb radial forces) and roller thrust bearings or four-point-angular-contact bearings (to absorb axial force).
减速机箱体采用钢板焊接结构。全部齿轮轴由滚动轴承支承(全部轴承选用进口轴承SKF或FAG), 齿轮材质采用优质钢(齿轮20CrNi2MoA, 轴42CrMo)渗碳、淬火、磨齿, 精度6级。集中循环稀油润滑系统对滚动轴承和齿面进行冷却和润滑北京英语翻译。
The reducer box body has a welded structure with steel plates, and all the gear shafts are supported by rolling bearings (all the bearings shall be imported SKF or FAG); the gear shall be made of high quality steel (gear: 20CrNi2MoA; shaft: 42CrMo), carburized, quenched and ground, with an accuracy of Grade 6. The centralized circulative oil lubricating system will cool and lubricate the rolling bearings and the gear surface.
轧机压下装置采用液压马达自动压下和手动压下两种形式。液压马达进回油口设快换接头。轧辊压下装置通过蜗轮, 蜗杆和压下螺丝连续完成。传动侧和操作侧可单独和同时压下。压下量显示设有可视的刻度盘翻译公司。
The press-down device of the rolling mill has two working modes: automatic press-down by a hydraulic motor or manual screw-down; a quick coupler is arranged at the oil feed and oil return ports of the hydraulic motor. The press-down device runs continuously through the worm wheel, the worm gear and the press-down screw. The transmission side and the operation side can be pressed down separately and simultaneously; a visible dial is provided to show the extent of press-down.
