滚动轴承的种类繁多,装配与调整方法也各有差异,本文仅闸明若干基本概念和主轴等重要部位轴承的装配与调整要领。一、滚动轴承的精度按GB307-77《滚动轴承技术条件》规定,滚动轴承的精度为G、E、D、C四级,C级最高,G级最低。G级为普通级,又称标准级,在轴承上不作标记。因此,凡没有标明精度等级的轴承,就是G级。 A wide range of rolling bearings, assembly and adjustment methods are also different, this article only a few basic concepts and main shaft spindle and other important parts of the bearing assembly and adjustment essentials. First, the accuracy of rolling bearings According to GB307-77 “technical conditions of rolling bearings,” the accuracy of rolling bearings G, E, D, C four, C-level highest, G-level minimum. G-class for the general level, also known as the standard level, not marked on the bearing. Therefore, where there is no indication of the level of precision bearings, is G-class.
