摘要
珩齿已经成为齿轮精加工的一种重要方法。研究珩齿加工机理,准确把握珩削速度和磨粒粒度等因素对齿面粗糙度的影响大小,对于提升被加工齿轮表面质量有着重要意义。根据内齿珩轮强力珩齿加工特点,通过对内齿珩轮和工件相对运动的分析,建立了内齿珩轮与加工工件表面各点运动线速度方程;基于实际加工参数,应用经典磨削理论实现对珩齿加工工件粗糙度的预测,探究齿面不同齿高处粗糙度变化规律;使用三维形貌仪对内啮合珩齿工件齿轮表面粗糙度进行测量,并将粗糙度预测结果和测量结果进行了对比分析,验证了该规律的正确性。研究对提升珩齿加工质量具有重要意义。
Honing has become an important method of gear finishing.It is of great significance to study the honing mechanism and accurately grasp the influence of honing speed and particle size on the roughness of the tooth surface in order to improve the surface quality of the machined gear.According to the characteristics of strong honing of inner gear honing gear,through the analysis of the relative motion of inner gear honing gear and workpiece,the linear velocity equation of each point on the surface of inner gear honing gear and machined workpiece is established.Based on the actual machining parameters,the classical grinding theory is applied to predict the roughness of honing workpiece,to explore the variation of roughness at different tooth heights on tooth surface,and to use three-dimensional morphology.The surface roughness of the gear of the internal mesh⁃ing honing workpiece is measured,and the roughness prediction results and the measurement results are com⁃pared and analyzed.The results verify the law,which is of great significance to improve the honing quality.
