The Design and Lateral Fluctuate Analysis of a New Double-Pitch Silent Chain for Conveyors

In order to reduce the lateral fluctuate in the conveying process of double-pitch roller chain for conveyors and implement smooth and steady conveying and based on the engagement theory and design method of silent chain, a new type of double-pitch silent chain for conveyors was proposed. Its chain plate was designed and analyzed its time-shared meshing theory and the reason of lateral fluctuates. and when rotating speed ω = 400 r/min, rotational resisting moment T = 20 Nm, a compared simulation tests between the new double pitch silent chains for conveyors and traditional double pitch roller chains for conveyors about lateral fluctuate values had been done. The analysis results show that the lateral fluctuate value of double pitch silent chain was largely smaller than the double- pitch roller chain's and the design could improve the conveying conditions distinctly. Therefore, the design of double-pitch silent chain for conveyors has value of application.
