摘要

The grinding process of bearings exhibits low energy efficiency and high grinding temperatures, while the utilization of grinding fluids results in significant electrical energy and resource consumption. These make it a machining method characterized by high resource consumption, energy consumption, and emissions. Therefore, this paper analyzed the grinding motion contact of the bearing ring and established a single-grain tangential grinding force model and grinding energy consumption and carbon emission model considering no-load power and load power. On this basis, the theoretical model of the maximum grinding temperature considering the heat source distribution was established. In addition, the finite element simulation of the grinding temperature field of the bearing ring was carried out by using ANSYS. The grinding experiment platform of the bearing ring (inner ring) was built. The single factor experiment of grinding was designed. The effects of grinding process parameters on grinding force, Maximum grinding temperature, grinding energy consumption, and carbon emissions were analyzed, and the relationship between them was explored. The errors of the simulation results and the calculation results with the actual experimental results are within 10%, which proves the correctness of the theoretical simulation model. The model can effectively guide the bearing grinding processing to realize the development concept of green manufacturing and clean production.
