As a result, this can reduce the chain noise and improve the work environment. The new designed low noise chain is equal with the normal roller chain in service performance, but obviously improvement in the noise lever.
为研究低噪声滚子链降噪性能,特对同等规格普通滚子链与低噪声滚子链做噪声对比试验,并对试验结果进行了分析与评价。

国内曾开展过普通滚子链的疲劳寿命分布规律的研究，得出一些有意义的结论，但由于汽车链与普通滚子链的设计方法和制造技术的不同，因而其疲劳寿命的分布规律及其特征参数也存在着差异，并且汽车链的高速、大载荷、强耐磨以及速度与载荷的交变特性，已使其失效机理和失效形式发生了根本变化，构成了学科发展的前沿研究领域，也是国内链条制造业亟待解决和汽车主机厂极为关注的关键技术。
