对预拉强化工艺提高农机用滚子链的疲劳强度进行了研究，并经过大量试验建立了预拉载荷与滚子链疲劳寿命间的关系。为链条生产企业提供了一条改善链条抗疲劳性能的途径
The fatigue strength of the roller chains for agricultural machinery is improved by the pre-tensioning process. After a large number of experiments, the relationship between the pre-tension load and the fatigue life of the roller chain is established. For chain manufacturers to provide a way to improve chain anti-fatigue performance
