摘　　要：针对齿轮工件几何形状的复杂性和现有抛光方法的局限性,开展了电解质等离子体抛光齿轮的实验研究,观察抛光过程中气层的动态变化,分析齿轮的几何形状变化和表面微观形貌,最后通过有限元仿真揭示了齿轮及其附近电解液的电势和电场分布规律。实验结果表明,电解质等离子体抛光技术能有效改善齿轮表面质量,表面粗糙度由Sa0.556 μm降至Sa0.362 μm,但针对粗糙度值较高的轮齿表面,该方法不具备轮齿修形能力。仿真结果表明,电压降主要集中在齿轮工件附近,齿轮工件附近电场整体分布均匀,但齿轮轮廓上曲率突变的位置有一个较大的电场波动。In response to the complexity of the geometric shape of gear workpieces and the limitations of existing polishing methods,experimental research on gear electrolytic plasma polishing was conducted.The dynamic changes of the gas layer during the electrolytic plasma polishing process were recorded,and the geometric shape changes and surface microstructure of the gear were analyzed.Finally,finite element simulation was carried out,revealing the potential and electric field distribution laws of the gear and its surrounding electrolyte.The experimental result showed that electrolytic plasma polishing technology can effectively improve the surface quality of gears,reducing the surface roughness from Sa0.556μm to Sa0.362μm.But for gear tooth surfaces with higher roughness,this method does not have the ability to modify gear teeth.The simulation result showed that the voltage drop is mainly concentrated near the gear workpiece,and the overall distribution of the electric field around the gear workpiece is uniform.However,there will be a large electric field fluctuation at the position of curvature mutation on the gear profile.
