多方位传动输送链设计与仿真研究

Simulation and design of poly-directional conveying chain

针对目前输送链在三维空间内多方位传输困难、噪音大等问题,设计了一种由外链片、内链片、套筒、滚子、销轴组成的新型可扭式多方位传动输送链条,链条相邻链节间通过内外链片相互固定,因而转动时链片间不会产生相对运动,同时减少了链板间的摩擦并降低了工作噪音。在合理简化的前提下,采用机械系统动力学软件ADAMS建立了该输送链的输送动力学模型,并进行了性能仿真研究,分析了传动过程中各零部件的受力情况,为进一步改进输送链设计提供了参考依据。研究结果表明,该传动输送链可在保持较低运动噪音的情况下,实现三维空间内任意工况路线运输传动,同时检测结果表明,该输送链具有良好的力学性能指标。

Aiming at the problems of noise,hard conveying of conveying chain in the three dimensional space,a new style of poly-directional conveying chain,which consisted of inner link,outer linker,sleeve,roller,pin,was designed. The chain elements were secured each other by inner link and outer link,so the links could not be moved between each other and the work noise was reduced. The transmission dynamics performance of the chain was researched and the force of each component and parts was analyzed on the mechanical system dynamics software ADAMS. The results could provide design reference for the chain. The results indicate that the new poly-directional conveying chain can realize any conveying route in the three dimensional space under complex operating conditions and the test results show that it has an excellent performance in the mechanical property.
