砂带磨损对螺杆转子磨削去除深度影响分析
Analysis of the influence of abrasive belt wear on the removal depth of grinding screw rotor
摘要
Abstract
To ensure the uniformity of material removal during surface grinding of screw rotors,a mathematical model for the material removal depth of screw rotors is established,considering the impact of abrasive wear on grinding re-moval depth.Based on the theory of elastic-plastic deformation and the wear pattern of abrasive particles during grind-ing,a theoretical model for the removal rate of single abrasive material is established.The wear of abrasive particles is divided into two stages:the rapid wear stage and the stable wear stage.Based on the number of abrasive particles per unit contact area and the rule of abrasive cutting edge,the maximum cutting depth of abrasive particles is calculated by numerical integration and contact pressure,and the mathematical model of macroscopic material removal rate based on abrasive belt wear is established.The model consideres the wear of the sand belt.The maximum error of the predicted value is 9.6%,and the minimum error is 4.1%compared with the experimental value.The experimental data fully veri-fy the effectiveness of the model,and can provide a theoretical basis for ensuring the profile accuracy of the screw rotor.关键词
