| 为了探究轴承与壳体压装过程中压机的选型问题，课题组基于弹性力学理论对压装力的大小进行理论计算，采用Inventor三维软件建立壳体和轴承三维模型，应用Workbench软件进行压装过程仿真，得出了过盈装配应力应变情况以及轴承、壳体装配时压装力 位移曲线关系。通过伺服压机的压装试验，分析并验证轴承壳体压装力和位移的理论关系以及压装力 位移曲线实时变化规律。研究结果表明：压装过程中力的理论计算和仿真分析可计算出最大压装力，根据最大压装力的大小和压装性能要求来确定压机型号；根据确定的方案进行工艺试验，并将试验结果与理论分析进行对比，验证了方案的可行性及准确性。分析结果可为轴承壳体压装动力源的选型提供参考。 |

| In order to investigate the selection of pressing joining device in the assembly process of bearing and housing , the stress strain of interference assembly and the relationship between press joining force and displacement curve of bearing and housing assembly were obtained by the theoretical calculation of the press joining force based on the theory of elasticity, the establishment of bearing and housing 3d models by Autodesk Inventor Professional and the simulation of the pressing process by Workbench. Through the press fit test of the servo press, the theoretical relationship between the press joining force and displacement of the bearing housingand the real time change law of the press joining force displacement curve were analyzed and verified. The research results show that the maximum press force can be calculated by theoretical calculation and simulation analysis of the force in the pressing process, and the type of the pressing joining device is determined according to the maximum press joining force and the requirements of press performance. The process tests were carried out according to the determined scheme, and the test results are compared with the theoretical analysis to verify the feasibility and accuracy of the scheme. The analysis results provide a reference for the selection of power source for bearing housing press joining. |
