摘　　要：针对目前主轴轴心位置的表征存在明显误差的问题,分析了误差产生的原因,提出了轴心位置的精确表征方法。通过厘清主轴轴心与轴承中心的几何位置关系,分2种情况建立轴心实际位置(Δ_(x0),Δ_(y0))与轴承表面偏移量Δ_(x)和Δ_(y)之间的映射关系,实现了主轴轴心位置的精确表征,并通过算例验证了本文所提方法的有效性。Aimed at obvious errors existed in characterization of axis position of spindle,the causes of errors are analyzed,and an accurate characterization method for axis position is proposed.By clarifying geometric position relationship between spindle axis and bearing center,the mapping relationship between actual position of axis(Δ_(x0),Δ_(y0))and surface offset of bearing(Δ_(x) andΔ_(y))is established in two cases.The accurate characterization of axis position of spindle is realized,and the effectiveness of proposed method is verified by an example.
