设计过盈联接时,常用公差配合表选取过盈量,要转换与材质的关系(强度校核)十分繁琐,且很难求得最佳设计尺寸。因此,在机械设计和设备维修中,应用甚少。本文提出过盈量等于或小于材质屈服强度不用强度校核,配合部位也是安全的,即δmax≤σs。1过盈配合表的改进之一根据弹性定律( Design interference connection, the commonly used tolerance table selection interference, to convert the relationship with the material (strength check) is very complicated, and it is difficult to find the best design size. Therefore, in mechanical design and equipment maintenance, rarely used. In this paper, the interference is equal to or less than the material yield strength without strength check, with the site is also safe, that δmax ≤ σs. 1 interference with one of the table improvement According to the law of elasticity (
