据大型带式输送机的使用实践表明,靠增大辐板的厚度h来提高接盘刚度,在许多情况下不能增大其强度;相反,从接盘的轮毂向辐板的过渡处却发现裂纹,即降低了接盘的使用寿命。下面分析滚筒转动时接盘的变形。我们把接盘看作为一个沿半径为r_B的内圆周边和半径为r_H的外圆周边固定了的光面圆板,它承受滚筒轴弯曲产生的和作用在刚度中心—接盘轮毂上的弯矩M_。(图1)。 According to the practice of using large belt conveyors, it is suggested that increasing the thickness h of the web to increase the rigidity of the connecting plate can not increase its strength in many cases; on the contrary, cracks are found from the hub of the connecting disc to the web, That is to reduce the service life of the disk. The following analysis of the disk rotation plate deformation. We consider the disk as a smooth disk fixed along the inner circumference of radius r_B and the outer circumference of radius r_H, which is subjected to bending of the drum axis and acting on the center of rigidity - the moment M_ .
