第一章 绪 论 钢球是球轴承中承载负荷的滚动体,它的质量好坏在很大程度上直接影响着轴承的动态性能和使用寿命。要了解钢球在轴承中的作用,必须先了解滚动轴承在机器中的工作承载情况。 一、轴承在工作中的承载情况 轴承在工作时,承受着由转动轴传递而来的径 The first chapter introduction ball is a ball bearing load bearing rolling body, its quality is good or bad to a large extent directly affect the bearing dynamic performance and service life. To understand the role of steel ball in the bearing, we must first understand the work of rolling bearings bearing capacity in the machine. First, bearing the bearing in the work bearing at work, borne by the rotating shaft diameter
