摘要

因多边形效应的存在,输送链尤其是大节距输送链在运动过程中始终承受周期性的冲击载荷。针对此问题,建立了大节距轨迹约束型输送链模型。根据链传动系统的啮合过程,将该模型分为链轮和链条上边两个部分。根据拉格朗日方程,建立了与之对应的动力学模型,并分别求出其广义力矩。为了更加精确地计算销轴与其他部分的接触应力,使用有限元软件ABAQUS建立了链轮-销轴和链节-销轴模型。将广义力矩代入计算,最终得到了链轮与销轴、链节与销轴之间的最大接触应力及其位置。为后期链条零部件的选材和热处理提供了一些参考。

Abstract

The conveyor chains bear a periodically impact loading due to the polygonal effect. The model of constrained trajectory of conveyor chains with long pitch is built toward this issue. The model is divided into two parts: chain wheel and top edge. The kinematics models of the two parts are established based on the Lagrange equation to calculate the generalized moment. In order to calculate the contact stress between the pins and other parts more precise,the models of chain wheel-pitch and pitch-pins are built by using the ABAQUS.The generalized moment is used to calculate the maximum contact stress and its position on pins. The consequence may provide some reference for the selection of material and the method of heat treatment.
