摘要

针对表面粗糙度和螺距误差对滚珠丝杠性能的影响,通过正交试验对磨削过程中影响滚珠丝杠粗糙度和螺距误差的因素:砂轮转速、修整进给速度、丝杠转速、磨削深度进行试验探究,确定各因素对滚珠丝杠性能影响的主次顺序和最佳组合。研究发现,磨削过程中,粗糙度最小的工艺参数组合为砂轮转速1 144 r/min,修整进给速度208 mm/min,丝杠转速16 mm/min,切削深度2μm。以上参数影响滚珠丝杠表面平均粗糙度的主次顺序为:砂轮转速→修整进给速度→磨床丝杠转速→切削深度。螺距误差最小的工艺参数组合为砂轮转速1 144 r/min,修整进给速度208 mm/min,丝杠转速16 mm/min,切削深度1μm。以上参数影响滚珠丝杠螺距误差的主次顺序为丝杠转速→磨削深度→修整进给速度→砂轮转速。

Abstract

Aiming at the influence of surface roughness and screw pitch deviation on the performance of ball screw,through orthogonal experiment method,the influence factors of grinding wheel speed,trimming feed rate,screw rotation speed and grinding depth on roughness and pitch deviation are explored,the primary and secondary order influencing on the performance of ball screw is determined. The research finding,in the process of grinding,the best combination of various processing parameters for roughness is that the grinding wheel speed takes 1 144 r/min,trimming feed rate takes 208 mm/min,screw rotation speed takes 16 mm/min,grinding depth takes 2 μm. The rank of each parameter variation from its maximum to minimum value is grinding wheel speed,trimming feed rate,screw rotation speed and grinding depth. The best combination of various processing parameters for pitch deviation is that the grinding wheel speed takes 1 144 r/min,trimming feed rate takes 208 mm/min,screw rotation speed takes 16 mm/min,grinding depth takes 1 μm. The rank of importance of each parameter variation from its maximum to minimum value is screw rotation speed,grinding depth,trimming feed rate,grinding wheel speed.
