The Relevant Technical Studies In Precision Retentivity Experiment Table Of Scroll Functional Components

Scroll functional components has many advantages, such as high precision, high efficiency, long life and so on. It’s widely used in machine tools, medical, aerospace, automotive and other fields.There is still a large gap between our country and some developed countries in scroll functional components precision retentivity.For studying the domestic scroll functional components precision retentivity, in this paper, the precision retentivity experiment table of scroll functional components was builded based on Shenyang Machine Tool Group’s products and analysis the Thermodynamic deformation. The experiment table is used to measure the linear rolling guide and ballscrews temperature variation、thermal deformation and positioning accaracy and etc.When the Linear rolling guide and ballscrews in the running, the friction will generate a lot of heat and generate thermal deformation the scroll functional components and experiment table may not be able to meet the requirements of precision machining. Based on the analysis of heat conduction and forces, the temperature field and thermo-mechanical coupled deformation of ballscrews and support of linear rolling guide were calculated on SolidWorks Simulation. The results show that the thermo-mechanical coupled deformation meet the accuracy requirement of the experiment. On the other hand, based on the analysis the ballscrews temperature field and thermal deformation under continuous lubrication conditions, the result show that continuous lubrication is an effective method to drop temperature.
