低温(深冷)过盈联接装配的应用是改善装配过程的先进方法之一。如被联接的零件上镶有防腐层时,只有使用冷却法,因为加热零件是不可能的。 用冷却法压装零件与其他压装法相比有许多优点:具有高的联接强度;不存在被联接表面在机械压入时产生的局部裂纹;没有因为加热出现的不良热
The use of cryogenic (cryogenic) interference fit assemblies is one of the advanced ways to improve the assembly process. If the parts to be joined are coated with a coating, use only the cooling method because it is not possible to heat the part. Press-fitting of parts by cooling has many advantages over other press-fitting methods: high joint strength; no localized cracks on the joining surface caused by mechanical press-in; absence of undesirable heat due to heating
