Description
技术领域technical field

背景技术Background technique
轴承广泛用于机械制造、航空航天、交通运输、能源、电力、采矿、冶金、建筑、化工、IT、家电等国防民用的几乎所有行业。滚动轴承是一种将运转的轴与轴座之间的滑动摩擦变为滚动摩擦，从而减少摩擦损失的一种精密的机械元件，用于高速旋转时的滚动轴承一般使用精密轴承。滚动轴承在高速运转的过程中，滚动体要产生离心力，离心力作用于轴承套圈，它和外加载荷一起，对套圈产生接触应力，接触应力是轴承疲劳破坏的主要原因。特别是滚动体与内外套圈表面的摩擦接触，极易在使用过程中出现磨损疲劳损坏，降低了整体的使用寿命。Bearings are widely used in almost all industries of national defense and civilian use such as machinery manufacturing, aerospace, transportation, energy, electric power, mining, metallurgy, construction, chemical industry, IT, and home appliances. Rolling bearing is a kind of precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings used for high-speed rotation generally use precision bearings. During the high-speed operation of rolling bearings, the rolling elements must generate centrifugal force, which acts on the bearing rings. Together with the applied load, it produces contact stress on the rings. Contact stress is the main cause of bearing fatigue damage. In particular, the frictional contact between the rolling elements and the surfaces of the inner and outer rings is very prone to wear and fatigue damage during use, which reduces the overall service life.
