摘要

20A-2型驱动链是自动扶梯常用的驱动链型号之一。本文对已有5年历史的传动链进行了拉伸性能测试。分析了材料的拉伸性能和显微组织。拉伸试验结果表明，拉伸强度符合相关标准要求。显微组织分析结果表明，外链板和中间链板表面存在不良脱碳现象。

Tensile property analysis of 20A-2 escalator drive chain

The 20A-2 drive chain is one of the commonly used drive chain models for escalators. In this paper, the tensile properties of a 5-year-old drive chain were tested. The tensile properties and microstructure were analyzed. The tensile test results show that the tensile strength meets the requirements of relevant standards. The results of microstructure analysis show that there are poor and decarburized phenomena on the surface of outer chain plate and intermediate chain plate.
