Precision ball bearings are widely used in military and civilian products. Due to technical blockades and other reasons, the domestic precision ball bearing market is in short supply, and even in some high-end compact ball bearings, it is in a blank state. How to manufacture high-precision and durable ball bearings has always been one of the difficult problems solved by domestic and international bearing manufacturers and even scientific research institutions.
The UGS software produced by UGS is a high-end 3D CAD software that integrates CAD/CAM/CAE. It includes modules for part design, 2D engineering drawings, part machining and simulation, and finite element analysis. Through the seamless integration between the modules, the three-dimensional information of the parts is shared between the design, the numerical control processing and the finite element analysis module, which is characterized by convenient design modification and rapid update.
In this paper, we take a grinding process of a high-precision ball bearing inner ring as an example, and carry out three-dimensional modeling through UG, and then carry out the necessary finite element analysis to determine a reasonable processing technique. Finally, the numerical control cylindrical grinding machine is used to realize the grinding production of high-precision ball bearing by numerical control interpolation, and the numerical control grinding program is programmed by UG software. The inner ring size of the ball bearing is shown in Figure 1. As can be seen from the figure, the part has high dimensional tolerance and shape tolerance requirements, all within μm level, and the surface roughness requirement is also high, at Ra0. Within .2μm.
