钢球是球轴承中非常重要,而且又是最薄弱的零件。众所周知,轴承在运转过程中,往往由于钢球疲劳的破坏,而使轴承失效。因此,钢球质量的好坏直接影响到轴承的疲劳寿命。国内在60年代和70年代的中期,对球轴承的寿命试验表明:因钢球的疲劳破坏,导致轴承破坏的比例为59.3％和58.8％。说明钢球是影响轴承寿命的 Ball is a very important ball bearing, but also the weakest parts. As we all know, the bearing in operation, often due to the destruction of the ball fatigue, leaving the bearing failure. Therefore, the quality of the steel ball directly affects the bearing fatigue life. Domestic In the mid-1960s and 1970s, the ball bearing life test showed that: due to the fatigue failure of the steel ball, the bearing damage caused by the ratio of 59.3% and 58.8%.
