Abstract and Keywords

Abstract: This paper established the prediction model of honing force of internal gear power honing. Firstly, the mathematical model of contact line and cutting thickness in honing meshing process was derived, and the grinding edge of honing wheel was separated into micro-element grinding edge based on this model. Then, the micro-element grinding edge model of honing wheel was established based on the plane grinding model, the honing force prediction model was established, and the variation law of honing force with process parameters was analyzed. Finally, based on Fassler HMX-400 CNC internal gear honing machine and its built-in Kistler force sensor, the honing force measurement experiment was carried out. The experimental results show that the numerical value and variation trend of the predicted honing force agree with the experimental measurement results, which verifies the validity of the method.

Keywords: internal gear power honing; honing force; plane grinding model; grind

摘要: 文章建立了内齿珩轮强力珩齿珩削力的预测模型。首先推导珩齿加工啮合过程中接触线和切削厚度数学模型，并基于此模型将珩磨轮的磨削刃离散为微元磨削刃；然后由平面磨削模型构建珩磨轮的微元磨削刃模型，建立珩齿珩削力预测模型，并分析珩削力随工艺参数的变化规律；最后结合Fassler HMX-400数控内齿珩轮强力珩齿机及其内置的Kistler力传感器进行珩齿珩削力测量实验。实验结果表明，预测的珩削力的数值和变化趋势与实验测量结果相符，该珩削力预测方法有效。
