Stress calculation of large scale driven drum supporting plates of belt conveyor
Abstract：In order to study stress calculation problems of large scale driven drum supporting plates of a belt conveyor, the mechanical model of a driven drum is established upon the condition that the torque acting on radial plates is omitted because it is smaller. The calcnlation formulas of bending moment and stress are de- rived according to solving methods of elasticity and statically indeterminate problems. It is known by analyzing the formulas that the calculating formula of bending moment of radial plates is a function in which there are 6 variable quantities, which are bearings spacing of a supporting shaft, the diameter of a supporting shaft, the space between 2 radial plates, the thickness of radial plates, the diameter of a wheel boss and the thickness of a cylinder. The contribution of these parameters to the stress of radial plates is different. If the load is con- stant, it is obvious that the stress of radial plates is decreased by means of the increasing dimneter of a support- ing shaft and the space between 2 supporting plates.
