摘　　要：在钢坯修磨机砂轮加载机构受力分析的基础上,对修磨机结构进行了优化.针对目前采用比例溢流阀和伺服阀加载存在的不足,提出在钢坯修磨机上采用比例三通减压阀加载.通过仿真研究及实际应用表明,在修磨机上采用这种电液比例加载系统可取得较好的修磨效果.On the basis of force analysis on grinding wheel loading mechanism, structural optimization of grinding machine is carried out. Aiming at the disadvantages of present loading system applying proportional relief valve or servo valve, loading system with 3 way proportional pressure reducing valve is proposed. By simulation and practical application, it can be concluded that taking this means can acquire better grinding effects.
