摘　　要：为了减小链式输送机的横向波动量,增强输送的平稳性与准确性,基于齿形链啮合理论及设计方法,设计了一款新型的双节距齿形输送链,给出了设计参数方法,分析了其分时啮合机理以及横向振动产生的原因,基于Adams多体动力学软件建立了双节距齿形输送链与双节距滚子链的横向波动量对比仿真试验,提取仿真结果并进行处理,分析结果显示:与双节距滚子链相比,双节距齿形输送链的横向波动量明显降低。可见,双节距齿形输送链的设计具有实用价值。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. 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. And then extracted and treated the simulation results. The analysis results show that the lateral fluctuate value of double pitch silent chain is largely smaller than the double-pitch roller Chain＇s and the design could improves the conveying conditions distinctly. Therefore, the design of double-pitch silent chain for conveyors has Value of application
