Design and Experimental Analyse of Low Noise Double-Pitch Silent Chain for Conveyor

Abstract

In order to improve current problems of large noise of double-pitch roller chain for conveyors, and implement higher efficiency and accuracy, a new type of double pitch silent chain was proposed by the method of change some plates with Nano-structured metal mesh - polyurethane composite material. Tested the noise characteristics among the new type double-pitch silent chain, the double-pitch roller chain and the short-pitch silent chain for conveyor and analysed the results. The results show that this new type of chain could effectively increase the transmission speed, ease chordal action, reduce the impact between chian plates and the sprocket tooth, and noise reduction effect is obvious. And the design could improve the conveying conditions distinctly. Therefore, the design of double-pitch silent chain for conveyors has value of application.
