摘　　要：密炼机转子(转子体与转子芯轴组成)采用热装配方法实现过盈配合,装配期间转子体热变形和热应力易引起转子体与转子芯轴间产生缝隙,从而导致转子漏水。针对GK320型密炼机转子热装配过程建立转子模型,采用ANSYS有限元软件对不同过盈量下的转子进行温度场分析,并将温度场作为条件进行转子体热变形和热应力分析,得到过盈量与转子体热变形和热应力之间的关系。本研究结果可为密炼机转子的设计、加工和装配提供参考。The interference fit of the mixer rotor(composed of the rotor body and rotor core shaft)could be achieved by thermal assembly;however,the thermal deformation and thermal stress of the rotor body during the assembling could easily cause cracks between the rotor body and the rotor core shaft,thereby causing water leakage.In this study,a rotor model was established for the thermal assembly process of GK320 mixer rotor,and the temperature field of the rotors with different interferences were analyzed by using ANSYS finite element.Then,the thermal deformation and thermal stress were analyzed using temperature field of the rotor body,and the relationship between the interference and the thermal deformation and thermal stress of the rotor was obtained.The results of this study could provide references for the design,processing and assembly of the mixer rotors.
