轴承的功能是支承轴及轴上零件。根据摩擦性质不同,轴承可分为滚动轴承和滑动轴承两大类,滚动轴承是标准组件,具有摩阻小,起动灵敏、润滑方便、易于互换等优点,应用极为广泛;而滑动轴承中的液体摩擦轴承,运转平稳、高速或重载条件下能长时间连续工作,这些特点又是滚动轴承所不具备的。为此,应了解两类轴承的特点,合理选用。 通过<轴承>一章的学习,主要应掌握的内容是:(1)合理选用滚动轴承类型,通过承载能力计算确定轴承型号;(2)合理选择滑动轴承的结构形式、材
The function of the bearing is to support the shaft and shaft parts. According to the different nature of friction, the bearings can be divided into two major categories of rolling bearings and plain bearings, rolling bearings are standard components, with a small friction, start sensitive, easy lubrication, easy exchange, etc., the application is extremely broad; and sliding friction in the liquid Bearing, smooth operation, high-speed or heavy conditions can be a long time continuous work, these features are rolling bearings do not have. To this end, should understand the characteristics of two types of bearings, a reasonable choice. Through the chapter of learning, the main content should be: (1) a reasonable choice of type of rolling bearing, bearing capacity through the calculation to determine the bearing model; (2) a reasonable choice of sliding bearing structure, material
