一、前言在叙述正文之前,让我们回顾一下下面几种情况:(1)机器的质量与轴承的设计和结构有关。要解决轴承问题,首先要决定该选用哪一种轴承——滚动轴承或滑动轴承,而这只有在详细分析了工作条件和要求之后才能决定。每种轴承皆有其特点,虽则目前滚动轴承无论在技术上和生产上都已达到高度发展阶段,然而在机械中仍有一定的场合非采用滑动轴承不可。滚动轴承还不可能完全取代滑动轴承。(2)滚动轴承之所以为设计者广泛采用,除了它本身具有某些优点之外,—部分原因应归功于它的计算方法简单化、图表化,设计者便于结合工作条件而正确选用。滑动轴承则直至不久以前尚缺乏象滚动轴承那样科学的、简单明了的计算基础,各有各的经验计算 First, the preamble In the narrative text, let us review the following situations: (1) the quality of the machine bearing design and structure. Bearing to solve the problem, we must first decide which kind of bearing the election - rolling bearings or plain bearings, and this only after a detailed analysis of the working conditions and requirements before the decision. Each bearing has its own characteristics, although the current rolling bearing both in technology and production have reached a high stage of development, however, there are still some occasions in the machinery non-use of plain bearings can not be. Rolling bearings can not completely replace plain bearings. (2) The reason why the rolling bearing is widely used by the designers is that besides its own certain advantages, it is partly due to the simplification of its calculation method and the charting, and the designer can easily choose the right combination of the working conditions. Until recently, the sliding bearings lacked a scientific, simple and clear calculation basis as rolling bearings, each with its own empirical calculation
