滚动轴承的内圈与轴、外圈与轴承座选择适当的配合是非常重要的。虽然有关资料对滚动轴套的配合选择有专门的介绍,但查阅比较麻烦,不易抓住重点。特别是1980年新的“公差与配合”国家标准颁布以来,还没有见到有关使用新国标选择滚动轴承配合的资料。本文试图用简明的概念和一些选择原则,并以新国标为对象,给设计人员提供一条选择滚动轴承配合的方便途径。 Rolling the inner ring and shaft, outer ring and bearing seat to choose the appropriate fit is very important. Although the relevant information on the choice of rolling sleeve with a special introduction, but access to more trouble, not easy to grasp the key. Especially since the promulgation of the new national standard “Tolerance and Cooperation” in 1980, there has not been any information on how to use the new national standard to choose a rolling bearing. This article attempts to use a concise concept and some selection principles, and the new national standard for the object, to provide designers with a choice of rolling bearings with a convenient way.
