Design And Experimental Research Of Escalator Handrail Drive System

In this paper, the analysis of handrail's circle is considered with the bending tension, centrifugal force, flexible slide between handrails and the friction wheels.Running resistance and consume power were analysised in detail corresponding different structures. Acording these formulas simulation model was established. The results of calculation about factors'relations were achieved by simulation.And ways to reduce the consume power were ahieved. Power consumptions of different structures were compared,and the suitble structure for different heights were achieved.Research of friction wheels'mechanisms were done. An especial equipment was developed for experiments.Those which effets factor between handrail and friction wheel were experimented. Datas of experiments shows: the higher tension and the greater angle,the more higher friction coefficient;grooves on the friction wheel's surface should be shallower, narrower. The nitrile rubber should be used on friction wheels,especially outdoor.
