摘要
介绍设计过程中选用过渡配合时 ,应用概率统计理论 ,精确设计过渡配合中需要出现过盈、间隙配合概率的方法。在选用过渡配合时 ,准确计算出现过盈、间隙配合的概率。并介绍了大批量生产及中小批量生产时出现过盈、间隙配合概率的计算方法 ,为要求较严格配合公差时的过渡配合公差选用提供了计算方法 。
This chapter introduces a way by which interference fit or clearance fit probability needed in transition fit can be exactly designed,when selecting transition fit and applying probability statistic theory.Meanwhile a calculating means is introduced too,which is applied in massive batch production and middle-small batch production where interference fit or clearance fit probability appears.A calculating means is provided for transition fit tolerance selection when requiring strict fit tolerance,which makes transition fit tolerance selection has higher precision and theory basis.
