Research on Material Damage Modes of Escalator Drive Chain

Abstract:

The use crowd of escalators involves a wide range of people. Therefore, the safety research of escalator is concerned and should be pay more attention to continuously. In the present paper, the multiple material damage modes of escalator drive chain were analyzed. The material damage modes mainly contain the micro cracking, the wear damage and the decarburization defect. The tensile tests and friction&wear experiments were performed to investigate the influence of the material damage modes on the performance of the escalator drive chains in service. The tensile properties of the new drive chains without material damages were superior to those with decarburization defect and wear damage. The friction&wear experimental results indicated that the decarburization defects reduced the wear resistance of the escalator drive chain. The research results implied that the strict quality control and improved maintenance of the escalator drive chain was meaningful for the escalator using security.
