双节距齿形输送链条设计与试验

Design and Experiment of Double-pitch Silent Chain for Conveyors

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。

Abstract:

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.
