摘要:
利用磁粒研磨加工工艺对轴承内圈进行光整加工实验，以降低其表面粗糙度值为目的，通过Ansoft Maxwell磁场模拟软件对磁极三种形状进行仿真分析，得到磁极开轴向槽磁场强度大，在此基础上研究了磨料粒径、磁极转速和研磨液用量对表面粗糙度值的影响。结果表明：当磨料粒径为185 μm时，磁极转速为600 r/min、研磨液用量为6 mL，光整加工60 min，轴承内圈的表面粗糙度值由原始的0.51 μm下降至0.10 μm，表面的划痕、刀微纹基本全部去除，表面形貌的均匀性较好，表面的显微硬度由原始的820 HV变为了900 HV，研磨后的表面强度增加了。
Abstract:
In order to reduce the surface roughness of bearing inner rings, the magnetic pole shape was simulated and analyzed by Ansoft Maxwell magnetic field simulation software. It was found that the magnetic field intensity of magnetic pole slot was high. Based on this, the influence of abrasive particle size, magnetic pole speed and the amount of grinding fluid on the surface roughness was studied. The results showed that when the abrasive particle size was 185 μm, the speed of magnetic pole was 600 r/min, the amount of grinding fluid was 6 mL and the finishing time was 60 min, the surface roughness of bearing inner ring decreased from 0.51 μm to 0.10 μm. The surface scratches and knife micro-lines were basically removed. The surface morphology was uniform. The surface micro-hardness changed from 820 HV to 900 HV, and the surface strength increased after grinding.
