摘要
阐述了预拉能提高链条疲劳强度的机理，并通过对１２Ｂ农用滚子链进行预拉和不预拉的对比试验，对试验结果进行处理，表明预拉可以大幅度提高链条的疲劳强度。
This paper explains the mechanism of the fatigue strength could be increased through preloading on the roller chain and analyzes the fatigue test results of 12B roller chains that are preloaded and unpreloaded using the statistical method. And the conclusion indicates the fatigue characteristics can be improved obviously by means of preloading on the roller chains.
