摘　　要：为解决滚齿加工中存在的齿面粗糙度不高问题,通过选择不同滚刀前刀面质量、顶刃圆角半径及滚刀刃口形状等进行滚齿加工实验,分析影响齿面粗糙度的具体因素及影响结果。研究表明,在加工材料和齿形轮廓无法优化的条件下,通过提高滚刀前刀面质量、增大滚刀顶刃圆角半径能获得较高的齿轮表面质量;采用大的刃口圆弧滚刀得到的齿轮零件表面质量要优于采用小的刃口圆弧滚刀。In order to solve the problem of low tooth surface roughness in gear hobbing,experiments are carried out by selecting different hob rake surface quality,top edge fillet and hob edge shape,and the specific factors and results affecting the tooth surface roughness are analyzed.The results show that when the machining material and tooth profile can not be optimized,higher gear surface quality can be obtained by improving the quality of hob rake face and increasing the fillet radius of hob top edge;The surface quality of gear parts obtained by using large edge arc hob is better than that by using a small edge arc hob.
