1、光滑极限量规设计一、概念（单向磨损量规）检跄工件最大实体尺寸（即孔为最小，轴为最大极限尺寸）的量规称为通规。检跄工件最小实体尺寸（即孔为最大，轴为最小极限尺寸）的量规称为止规。二、量规公差带图光滑量规的通规应等于或接近工件的最大实体尺寸;光滑量规的止规应等于或接近工件的最小实体尺寸:三、量规偏差计算公式1、孔用量规计算公式：通规上偏差Ts=EI+Z+T2通规下偏差Ti=EI+Z-T2通规磨损极限Tu=EI止规上偏差Zs=ES2、轴用量规计算公式通规上偏差Ts=es-Z+T2通规下偏差Ti=es-Z-T2通规磨损极限Tu=es止规上偏差Zs=ei+T止规下偏差Zi=ES-T止视下偏差Zi=ei标
