Study on the reliability evaluation method of the wear life of roller chains

Abstract

Wear resistance property is one of the important characteristics of the intrinsic quality of chains. Formerly, the evaluation index for the quality of roller chains was based on ISO606-94. However, because that version of standardization was mainly related to the exchangeability of dimensional parameters, it was difficult to assess the wear life and reliability of roller chains. The promulgation and implementation of ISO10823-96 makes it now possible to evaluate the life and reliability of roller chains. Based on the sampling theory, this paper discusses in depth the reliability evaluation method of assessing the life of roller chains. A method is proposed to obtain higher quality and reliable roller chains that show good wear properties. A sampling scheme for reliability inspection has also been devised.
