摘　　要：为了合理确定不同规格刮板输送机槽帮榫头厚度,建立了槽帮榫头及哑铃销的三维模型。在分析了哑铃销窝处应力与位移随哑铃销拉力关系的基础上,研究了不同槽帮榫头厚度与承载力的关系。结果表明:哑铃销窝随哑铃销拉力的增加由弹性变形变为塑性变形;哑铃销窝处位移随拉力呈指数增加;榫头厚度与承载力呈近似线性关系,并得到了定量的函数关系。In order to get the thickness of scraper conveyor ledge tenon properly, 3D model for ledge tenon and dumbbell pin is created. On the basic of analyzing the stress and strain changes on dumbbell pin fossa following the dumbbell pin tension, the relationship between the thickness of ledge tenon and bearing capacity is analyzed. The result show that the deformation of dumbbell pin fossa changes from elastic deformation to plastic deformation; the displacement of dumbbell pin fossa increases exponentially; the ledge tenon thickness increases approximately linearly followed by bearing capacity, and the quantitative function is obtained.
