【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 transmission performance and reliability of chain conveyor, based on the meshing mechanism of tooth chain, a double pitch time-sharing meshing tooth chain is designed, and the relevant design parameters are given. Based on ADAMS, a comparative simulation model of tight edge fluctuation and meshing impact force between two pitch time-sharing meshing gear chain and double pitch roller chain is established. The simulation results show that, compared with the double pitch roller chain, the double pitch time-sharing meshing chain is stable, the fluctuation of tight edge is reduced by 59%, and the meshing impact force is reduced by 51.9%. The noise test and the wear test for 250 h were carried out on the closed force flow chain test bench. Compared with the double pitch roller chain, the average noise at the tight edge meshing point of the double pitch time-sharing meshing chain was reduced by 4.6 dB compared with the double pitch roller chain, and the mean noise at the tight edge meshing point of the double-pitch time-sharing meshing chain was reduced by 4.6 dB. The wear elongation is reduced by 0.28. The experimental results show that the design of the two-pitch time-sharing meshing tooth chain is reasonable.
