预紧双列调心滚子轴承径向游隙控制

Analysis on radial windage of pre-tight double row heart-adjusted roller bearings

以双列调心滚子轴承为例,从理论上分析预紧滚动轴承径向工作游隙的影响因素以及工作游隙对轴承使用寿命的影响,并给出轴承预紧前最佳原始游隙的计算公式。实践证明这种方法可以保证轴承在具体的工作条件下处于最佳的工作游隙状态,达到最长的使用寿命。

With double-row heart-adjusted miler bearings as the example, analyzed theoretically on the factor that affected radial windage of pre-tight double mw heart-adjusted miler bearings and how it affects service life of the bearing. It presents calculating formula to computer optimally original windage before the bearing pre-tight. It turned out that this method could assure bearing in optimal windage condition in concrete working condition, accordingly achieve the longest service life.
