【摘要】：链刮板输送机是综采工作面最重要的物料输送装备,链轮链条是刮板输送机传送系统的核心部件,链轮链条的啮合问题是传动系统最突出的问题。为了研究卡链工况下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,分析正常运行至卡链工况下链轮与链环接触的动力学特性。分析得出圆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Workbench软件对链轮链环啮合过程进行了接触应力分析,得出链轮链环啮合过程中接触应力最大值和对应的位置,为刮板输送机链轮链环的优化设计提供了理论依据。
[Abstract]:Chain scraper conveyor is the most important material transportation equipment in fully mechanized mining face. Sprocket chain is the core component of scraper conveyor transmission system, and the meshing problem of sprocket chain is the most prominent problem in transmission system. In order to study the law of contact force between sprocket and sprocket in the meshing process of sprocket and sprocket under chain clamping condition, the meshing process of sprocket and sprocket is analyzed theoretically, and the change of contact force in meshing process of sprocket chain is analyzed. Then the virtual prototype model of sprocket chain of scraper conveyor based on MSC.ADAMS is established, and the dynamic characteristics of the contact between sprocket and chain under normal operation to chain clamping condition are analyzed. The change law of contact force, contact tangential force and contact normal force in the meshing process between ring chain and sprocket, as well as the maximum value and corresponding position of contact force are obtained. Finally, the contact stress analysis of sprocket meshing process is carried out based on Workbench software, and the maximum contact stress and corresponding position in the meshing process of sprocket are obtained, which provides a theoretical basis for the optimal design of sprocket chain ring of scraper conveyor.
