介绍一下轴承的公差符号, 方便大家在看样本时更好的理解数据。
d/ds公称内径/单一内径(Nominal bore diameter/Single bore diameter)
dmp单一平面平均内径(Mean bore diameter;arithmetical mean of the largest samallest single bore diamerers measured in one radial plane)
△dmp单一平面平均内径偏差(dmp-d;Deviation of mean bore diameter from the nominal dimension)
△ds单一内径偏差(ds-d;deviation of single bore diameter from the nominal dimension)
Vdp单一径向平面内径变动量(Bore diameter variation;difference between the largest & smallest single bore diameters in one radial plane)
Vdmp平均内径变动量(dmp max-dmp min;Mean bore diameter variation;difference between the largest & smallest mean bore diameters)
D/Ds公称外径/单一外径(Nominal outside diameter/Single outside diameter)
Dmp单一平面平均外径(Mean outside diameter;arithmetical mean of the largest & smallest single outside diameters in one radial plane)
△Dmp单一平面平均外径偏差(Dmp-D;Deviation of mean outside diameter from nominal dimension)
△Ds单一外径偏差(Ds-D;Deviation of mean outside diameter from nominal dimension)
VDp单一径向平面外径变动量(Outside diameter variation;difference between the largest & smallest single outside diameter in one radial plane)
VDmp平均外径变动量(Dmp max-Dmp min;Mean outside diameter variation;difference between the largest & smallest mean outside diameters)
Bs/Cs内圈/外圈单一宽度(Single inner ring/outer ring width)
△Bs内圈单一宽度偏差(Bs-B; Deviation of a single inner ring width from nominal dimension)
△Cs外圈单一宽度偏差(Cs-C; Deviation of a single outer ring width from nominal dimension)
VBs内圈宽度变动量(Bs max-Bs-min; Variation of inner ring widths; difference between the largest & smallest single inner ring width)
VCs外圈宽度变动量(Cs max-Cs min; Variation of outer ring widths; difference between the largest & smallest single outer ring width)
B,C,T轴承公称宽度/高度(Nominal bearing width/height)
Ts轴承实际宽度/高度(Actual bearing width/height)
△Ts轴承实际宽度/高度偏差(Deviation of the actual bearing width/height)

Kea成套轴承外圈径向跳动(Radial runout of assembled bearing outer ring)
Sd内圈基准端面对内圈的跳动(Side face runout of inner ring with reference to bore)
SD外表面母线对基准端面倾斜度变动量(Variation in inclination of outside cylindrical surface to outer ring side face)
Sia成套轴承内圈轴向跳动(Axial runout; assembled bearing inner ring face runout with raceway)
Sea成套轴承外圈轴向跳动(Axial runout;assembled bearing;outer ring face runout with raceway)
r公称倒角尺寸(Norminal chamfer dimension)
rs径向/轴向单一倒角尺寸(Radial/axial single chamfer dimension)
rs min最小径向/轴向单一倒角尺寸(Smallest radial/axial single chamfer dimension)
rs max最大径向/轴向单一倒角尺寸(Largest radial/axial single chamfer dimension)
