摘要

为提高链式输送机的输送性能和可靠性,基于齿形链啮合机理,设计一款双节距分时啮合齿形链,给出相关设计参数,基于ADAMS建立双节距分时啮合齿形链与双节距滚子链的紧边波动量和啮合冲击力对比仿真模型。仿真分析结果表明,与双节距滚子链相比,双节距分时啮合齿形链啮合平稳,紧边波动量降低59%,啮合冲击力降低51.9%;对其进行台架对比试验,在封闭力流链式实验台上进行噪声测试和250 h的磨损试验,相比双节距滚子链,双节距分时啮合齿形链紧边啮合点处平均噪声降低4.6 d B,磨损伸长率降低0.28%,试验结果证明了双节距分时啮合齿形链设计的合理性。

Abstract

In order to improve the transportation performance and reliability of chain conveyor,based on the silent chain meshing mechanism,a double pitch time sharing meshing silent chain is designed,and the related design parameters are given. Base on the ADAMS,a simulation model is established to compare with the tight edge fluctuation and meshing impact force of double pitch time share meshing silent chain and double pitch roller chain. As the result of the stimulation analysis shows,compared with double pitch roller chain,the meshing of double pitch time share meshing silent chain is stable and the tight edge fluctuation is reduced by 59%,while meshing impact force is reduced by 51. 9%. Then it is compared with results of bench test,on the confined fluid chain bench,the noise test and the 250 h wear test are conducted,compared with that of double pitch roller chain,the average noise at the tight side mesh point of double pitch time share meshing silent chain is reduced by 4. 6 d B and the wear elongation is reduced by 0. 28%. The experimental results prove that the rationality of double pitch time share meshing silent chain design is reasonable.
