配合概率极限间隙和概率极限过盈的计算

Calculation of Probability Limit Clearances or Probability Limit Interferences

介绍了采用大批量生产方式生产的孔、轴实际尺寸的分布规律及由这些孔、轴组成配合后,其配合间隙和过盈的分布规律。定义了概率极限间隙和概率极限过盈,并推导出了它们的计算方法。另外,通过示例介绍了概率极限间隙和概率极限过盈在配合选择中的应用。

The paper introduced the law of Distribution of the actual sizes of the holes or the shafts that they were mass production; and the law of the actual fit clearances or the actual fit interferences after fitting these holes and shafts. Probability limit clearances and probability limit interferences were defined. Then deduce the way that to calculation the probability limit clearances and the probability limit interferences. In addition, the paper also introduced the application of the probability limit clearances and the probability limit interferences in the selection of fit via the typical example.
