摘要
压配合联按计算是以厚壁圆筒计算原理为基础的,它与配合件的机械强度和热处理状态没有联系。但生产实践中却发现压配合的压入力不仅与过盈量有关,而且与配合件的机械强度和热处理状态有密切关系,这表明压配合过程并非纯弹性变形过程,而是弹塑性变形过程,致使二次压装时出现压入力上升的现象。
The calculation of force fit connection is based on thick-wail cylinder princ-ple,it has nothing to do with the mechanical strength and heat treatment condition of fittingpiece. But the practice shows that force fit process is not elastic deformation process,it re-sults in the increasement of press fit force as twice pressing.
