E3立辊轧机侧压装置系统设计
摘要
立辊轧机的侧压装置每侧都有两根侧压螺丝,两台侧压电机通过蜗轮蜗杆减速机分别带动两侧的侧压螺丝完成辊缝调整工作。辊缝调整速度即一对立辊同时靠拢或张开的速度,对不同类型的立辊轧机差别较大。侧压速度取决于立辊开口度的变化范围,若开口度变化范围较大,则侧压速度要选得较大。现代的立辊轧机左右两个侧压装置之间都没有机械连接,完全采用电气同步,这省去了同步轴、离合器等一套复杂笨重的机械同步机构,并给轧辊的对中和换辊操作带来了很大的方便。平衡装置是通过放置在单侧两根侧压螺丝间的平衡液压缸,将轧辊拉靠在侧压螺丝上,以消除侧压螺丝和侧压螺母和其它承压件之间的间隙。
本设计通过计算对立辊轧机的侧压系统的机械结构和工作原理做了简略的分析，明确了该系统的优劣。为立辊轧机的侧压系统从而到整个机构的优化设计提供了基矗

Abstract
Vertical roller mill side pressure device has two lateral pressure screws on each side, two side pressure throughworm gear motors are driven by lateral pressure screws on both sides to complete the roll gap adjustment. Roll gap adjustment speed that a close or open at the same time opposing roller speed differences for different types ofvertical roller mill is large. Side pressurevaries depending on the speed of the opening degree ofvertical roll, if the opening of the large range ofvariation, the lateral pressure to choose a larger rate. Modern edger between right and left side pressing device is no mechanical connection, electrical completely synchronized,which eliminates the synchronizing shaft, clutch a complex bulky mechanical synchronizing mechanism, and a pair of rolls and roll change operation has brought great convenience. Balancing device is placed in equilibrium by two hydraulic cylinders unilateral lateral pressure between the screwwill pull the roll against the side pressure screw to eliminate the gap between the lateral pressure side pressure screw and nut and other pressure parts.
This design by calculation E_3 edger mill manometry system mechanical structure andworking principle madea brief analysis of the pros and cons of the system clear. Vertical roller mill manometry is thus to optimize the design of the system provides the basis for the entire organization.
