摘要

链传动系统是刮板输送机的关键部件,链轮链环是链传动系统的关键部件,驱动链轮与链环的啮合力学行为与驱动链轮的磨损相互影响。为了研究链轮与链环啮合过程中链轮与链轮接触力的规律,首先从链环与链轮啮合过程进行理论分析,并对链轮链环啮合过程接触力的变化进行了分析,然后建立基于MSC.Adams的刮板输送机链轮链环虚拟样机模型,分析正常启动至长期输送功率工况下链轮与链环接触的动力学特性,分析得出环链与链轮啮合过程中接触合力、接触切向力和接触法向力的变化规律及接触力的最大值和对应的位置,最后基于LS-DYNA软件对链轮链环啮合过程进行了接触应力进分析,得出链轮链环啮合过程中接触应力最大值和对应的位置,为链轮链环啮合接触研究提供了参考。

Abstract

The chain system is the key part of the scraper conveyor,the sprocket and the chain hoop is key component of the chain system. The engaging force between the sprocket and the chain hoop and the abrasion of the influence each other. In order to research the connection of the engaging force between the sprocket and the chain hoop,we first established the visual prototyping model based on the MSC. ADAMS and analyzed the touch dynamics quality between sprocket and chink hoop when the scraper conveyor starts and are operated for a long time. We acquired the change law of the contact resultant force tangential force and normal force when the sprocket and the chain hoop are engaging,and the maximum engaging force and the corresponding position. Finally we analyzed the engaging force when the sprocket and chain hoop during the engaging progress based on the software of LS-DYNA,and indicated that the maximum engaging force and corresponding position,which provides a reference for the study of the engaging dynamics of sprocket and the chain hoop.
