【摘要】：基于卧式研球机在研磨时钢球与研磨盘之间不发生打滑现象,建立钢球的研磨运动方程,并通过MATLAB软件求解揭示其运动规律。为使钢球在转动盘牵引力的作用下不发生打滑,从垂直沟槽面和沿沟槽面分别对其进行动力学分析,推导出研磨压力及研磨盘转速的取值范围。以研磨盘材料HT300和钢球材料GCr15为例,给出摩擦因数和钢球大小对研磨曲线的影响,并说明沟槽偏置时α与β的选择原则,为改善钢球的表面质量提供参考。研究结果表明:通过增大盘径来减小迹线间距的差值,进而使钢球表面的迹线分布更加均匀化。
[Abstract]:Based on the fact that the horizontal ball grinder does not slip between the ball and the lapping disk, the motion equation of the ball grinding is established, and the motion law is revealed by MATLAB software. In order to prevent the steel ball from slipping under the action of the traction force of the rotating disc, the dynamic analysis of the ball is carried out from the vertical groove surface and along the groove surface, and the range of the grinding pressure and the rotating speed of the grinding disc is deduced. Taking HT300 and GCr15 as examples, the effects of friction factor and ball size on the grinding curve are given. The selection principle of 伪 and 尾 when groove bias is explained, which provides a reference for improving the surface quality of steel ball. The results show that the difference between the trace lines is reduced by increasing the diameter of the disk, and the distribution of the trace line on the surface of the steel ball is more uniform.
