轴承沟道低粗糙度旋转磁场磁粒研磨研究
Research on low roughness rotating magnetic field magnetic particle grinding of bearing channels
摘要
Abstract
To reduce the surface roughness of bearing grooves,this paper designs a magnetic particle grinding device capable of generating a rotating magnetic field based on the alternating current excitation method.The bearing grooves are then polished,and orthogonal experiments are conducted to investigate the effects of four process parameters,namely SiC particle size,Fe particle size,machining gap,and workpiece speed on the surface roughness of the bearing grooves.The optimal combination of process parameters is obtained and the machining of the bearing grooves is verified under these conditions.The orthogonal experimental results show,under the experimental conditions of SiC particle size number 400#,Fe powder particle size number 115#,machining gap of 0.5 mm,and workpiece speed of 1 200 r/min,the surface roughness Sa of the sample reaches 0.056 μm;An analysis of the results of the orthogonal experiment using the range analysis method suggests the SiC particle size has the greatest impact on the surface roughness Sa of the sample channel while the Fe particle size the smallest.The optimal process parameter combination is:SiC particle size number 600#,Fe powder particle size number 120#,machining gap 1 mm,workpiece speed 1 200 r/min.By conducting a rotating magnetic field magnetic particle grinding test with this process parameter combination,the surface roughness Sa of the bearing groove is reduced to 0.044 μm.关键词
