过盈联接时，常用公差配合表选取过盈量，计算十分繁琐，且很难保证求得最佳设计尺寸，因此，在机械设计和设备维修中很少应用。倘若在配合零件的材质里和配合公称直径求得的过盈量列入表替代，传统的公差配合表就可以获得改进；这样能较好地发挥材料的强度性能，且可一次计算 Interference connection, the use of commonly used tolerance table to select the amount of interference, the calculation is very complicated, and it is difficult to ensure the best design dimensions, therefore, rarely used in mechanical design and equipment maintenance. If in the material with the parts and nominal diameter with interference calculated by the table included in the table, the traditional tolerances can be improved with the table; This will give better material strength performance, and can be a calculation
