O-RING密封设计规范及压缩量计算模板

INPUT VALUES:A cylinder bore diameter （与ORING 配合的孔径）(inches)

B groove diameter （装ORING 的槽径）(inches)D o-ring cross-sectional diameter （ORING 的线径）(inches)ID inside diameter of o-ring （ORING 的内径）

(inches)

CALCULATED VALUES:ST Percent of stretch of o-ring onto groove diameter(ORING 延伸率百分数）Y Reduction in cross-section factor based on stretch （ORING 装到槽上后受拉伸后的断面收缩率）D'effective o-ring cross sectional diameter after stretch （ORING 装到槽上受拉伸后的线径）(inches)

S squeeze on o-ring (0.007" is recommended minimum)（ORING 压缩量，建议静态时大于0.007″）

(inches)

Calculations for Min. Squeeze:最大压缩量

ST = [(Bmax - ID min)/ID min]*100155.885t

Calculations for Max. Squeeze:

Y = 1 - 10 / sqrt(100+ST)0.37486ST = [(Bmin - ID max)/ID max]*100150.2493D'min = Dmin - Y*Dmin

1.06899Y = 1-10 / sqrt(100+ST)0.367860.56899

D'max = Dmax - Y*Dmax 1.169460.66946
