摘要
对链板材料的疲劳强度、链板孔表面加工质量、链板应力集中、整链预拉强化、链板喷丸强化等影响滚子链疲劳寿命的规律进行了深入的研究，给出了提高滚子链疲劳寿命的工艺参数。
The paper studies the law of material fatigue strength of chain plate,suface processing quality of plate hole,stress concentration of chain plate,pre drawing of whole chain and shot peening of chain plate influence fatigue lifetime of roller chain in a deepgoing way.Technological parameters of improving fatigue lifetime of roller chain are given.
