Abstract
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 &omega = 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.
Highlights
Chain for conveyor is a kind of chain driving systems which are wildly used in machinery manufacturing, agricultural machinery, metallurgy and other fields to transport parts, goods or materials
Since the serious polygon effect and impact, the Lateral fluctuate is very large (Troedsson and Vedmar, 1999; Liu et al, 1998; Qin, 2010), which result in conveying error and increase the rejection rate
Some scholars make a series of deep researches on design methods (Meng et al, 2007; Liu, 2011), meshing theory (Meng, 2008; Xue et al, 2007; Meng et al, 2009), kinematics and the dynamic characteristics (Feng et al, 2005; Wang et al, 2007) and other sides researches about silent chain, which greatly enriched the types of silent chain and expanded its application range
Summary
Chain for conveyor is a kind of chain driving systems which are wildly used in machinery manufacturing, agricultural machinery, metallurgy and other fields to transport parts, goods or materials. Based on the previous studies of silent chain, we proposed a type of double-pitch silent chain to improve the problems existed in the conveyor with double-pitch roller chain. The double-pitch silent chain has the advantages of it has the advantages of high transmission speed and heavy load, and has the advantages of lighter weight. The analysis results show that the design of double-pitch silent chain produce a largely smaller lateral fluctuate than double-pitch roller chains. The new type of double-pitch silent chain is a kind of variation structure of standard silent chain which is mainly assembled by M-plate, reinforcing plate, guide plate and round pin.
