- 摘要:
- 为解决轴承内圈滚道表面抛光困难及研磨不均匀的问题,选用了开槽仿形磁极对轴承内圈滚道表面进行光整加工。采用Ansys Maxwell对比分析了开槽仿形磁极和仿形磁极的磁场分布,选用控制变量法探讨了各试验参数对轴承表面光整加工的影响。结果表明,在磁性研磨粒子粒径为185 μm,轴承与磁极间隙为2 mm,工件转速为1200 r/min的条件下,加工时间40 min,表面粗糙度由1.35 μm下降为0.13 μm,表面缺陷得到有效去除。
- Abstract:
- In order to solve the problem of difficult polishing and uneven grinding of the inner ring raceway surface of the bearing, slotted profiling magnetic pole is selected to finish the inner ring raceway surface of the bearing. The magnetic field distribution of the slotted profiling magnetic pole and the profiling magnetic pole was analyzed by Ansys Maxwell and the influence of test parameters on bearing surface finishing was discussed by control variable method. The results show that when the particle size of the magnetic abrasive grains is 185 μm, the distance between the bearing and the magnetic pole is 2 mm, the workpiece rotation speed is 1200 r/min and the processing time is 40 min, the bearing surface roughness could reduce from 1.35 μm to 0.13 μm. Surface defects can be removed effectively.
