一、引言如系统的实验巳能表明的那样,在采用一个未经修正的轧轮的时候,只要适当地设计轧轮并选择最佳的加工条件,就能够收到显著改善精轧圆柱齿轮质量的效果[1、2]。但是由于在未经修正的轧轮进行啮合的周期内,齿的弹性挠度是变化的,所以通常是不可能达到更高的啮合质量。在用未修正的轧轮(即所谓标准磨削的轧轮)作滚轧实验时,由于齿面滑动摩擦的大小不同,方向交变,所以,可以估计齿面金属材料一定会有不均匀的塑性流动。然而,
I. INTRODUCTION As systematic experiments have shown, when using an unmodified rolling wheel, the proper design of the rolling wheel and the selection of the optimum machining conditions can lead to significant improvements in the quality of the finished cylindrical gear The effect of [1,2]. However, since the elastic deflection of the teeth varies during the period of engagement of the unmodified rolling wheel, it is generally not possible to achieve a higher meshing quality. In the unmodified rolling wheel (the so-called standard grinding wheel) for rolling experiments, the sliding friction due to the tooth surface of different sizes, the direction of change, it can be estimated that the tooth surface metal material must be uneven Plastic flow. however,
