原650轧机压上装置传动结构如图1所示。 图1 650轧机原压上装置图 1-机架;2-铜螺帽;3-锯齿形压上丝杆;4-大齿轮 原压上装置存在下列问题:一是铜螺帽由于受巨大的轧制冲击力而易产生变形,与机架间出现楔形缝隙,并受水和氧化铁皮的侵蚀,或油泥和污垢充填,造成检修时拆卸困难;二是虽然有较完善的密 The original 650 mill pressure device transmission structure shown in Figure 1. Figure 1 650 mill original pressure on the device Figure 1 - 2-copper nut 3-serrated pressure on the screw 4-gear on the pressure device has the following problems: First, due to the huge copper nut Rolling impact and easy to produce deformation, wedge-shaped gap appears between the rack, and by the erosion of water and iron oxide skin, or sludge and dirt filling, resulting in disassembly difficulties when overhauling; Second, although there are more sophisticated
