【摘要】 讨论了能满足高精度要求的滚动轴承结构设计问题．采用使滚动体限定在给定的轨道内的“限位轴承”，达到摆动误差０．３～０．６″、主轴偏移量ｅ为０．５μｍ的指标．文中给出了计算示例．更多还原

【Abstract】 The construction design of precise axial system in engineering and calculation weresolved. It was put forward that by use of the position-restricting bearing which limited the rolling elements in given orbits, the indexes of oscillating angle within 0.3-0.6" and deviation ofprincipal axis being 0.5 μm could be achieved. A calculating example was given.更多还原
