摘要
研究了齿形链啮合机理和设计方法,提出了一种双节距齿形输送链条。对其结构特性及啮入冲击速度进行了分析,给出了链条主要设计参数及其关系式,并对其进行了200 h的磨损试验,试验结果表明:200 h后,双节距齿形输送链条的磨损伸长率仅为0.149%,明显低于传统的双节距滚子输送链条。验证了双节距齿形输送链设计方法的合理性。
A type of double-pitch silent chain for conveyors was proposed.Its structure was designed and the relative parameters and designed formula were given.And wear test for 200 h was done.The results showed that the ratio of wear elongation of double-pitch silent chain for conveyors was 0.149%,which was shorter 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 showed the feasibility of application.
