NJ系列圆柱滚子轴承双挡边超精工艺改进

摘要

The current processing method is introduced for double ribs on outer rings of NJ series cylindrical roller bearings,and the causes is analyzed for deficiency superfinishing of upper and lower ribs near raceway side.The superfinishing quality of double ribs is guaranteed by changing position of oilstone and contact shape,adjusting oscillation amplitude of oilstone.%介绍NJ系列圆柱滚子轴承外圈双挡边目前的加工方法,分析上、下挡边出现靠近滚道侧超精不到边原因,通过改变油石位置、接触形状,调整油石振荡幅度,保证了双挡边的超精质量.
