摘要: 为了探究成形法磨削齿轮的磨削温度生成机制与变化规律,构建了单位接触宽度齿面磨削力与成形法磨齿温度的理论模型,揭示了它们与砂轮特性、齿轮规格、磨削用量与材料特性的内在关系。成形磨齿温度随着砂轮磨刃密度、磨削速度、径向进给量的增大而增大,却随着砂轮直径、齿轮压力角增大而减小。齿轮的模数对齿廓磨削温度的影响较弱,而齿数对齿顶与齿根两处磨削温度的影响态势却截然相反。成形法磨削齿轮的砂轮特性系数τ越大,则磨削性能越差,并在一定程度上决定了轴向进给速度对磨削温度的影响规律。此外,通过正交试验回归模型分析法证实了成形法磨齿温度理论模型具有较好的实际适用性,且微晶刚玉砂轮的磨削性能优于白刚玉砂轮。

Abstract: To explore the generation mechanism and variation law of grinding temperature in gear grinding by forming method, the theoretical models of grinding force per unit contact width and form grinding temperature are established, and the internal relations with grinding wheel characteristics, gear specifications, grinding parameters and material characteristics are revealed. With the increase of grinding wheel density, grinding speed and radial feed rate, the temperature of gear grinding increases, but decreases with the increase of grinding wheel diameter and gear pressure angle. The influence of gear modulus on the grinding temperature of tooth profile is weak, while the influence of tooth number on the grinding temperature of tooth top and tooth root is opposite. The larger the wheel characteristic coefficient τ, the worse the grinding performance, which determines the influence of axial feed speed on grinding temperature. In addition, the regression model analysis method of orthogonal experiment proves that the theoretical model of gear grinding temperature of forming method has good practical applicability, and the grinding performance of microcrystalline corundum wheel is better than that of white corundum wheel.
