Finite element analysis of large-belt width conveyor driving roller

As a key component of the large-belt width conveyor, establishing mechanical model and adopting effective method to improve the design performance of the large-belt width roller is very important. In this paper, mechanical analysis was employed in large-belt width conveyor driving roller for the theoretical foundation of the subsequent analysis. The geometric model of the large-belt width driving roller was built, static analysis was made based on finite element analysis method, and the roller body structure was analyzed by post-processing along the circumferential direction and axial direction respectively. The results show that under the circumstance of ensuring welding quality, the damage of the roller will occur at a certain distance toward the central shell from the connection position of the inside flange and the roller shell, therefore the welding position of the cast welding structure at both ends should avoid the dangerous zone. Analyzing the stress and strain distribution of the roller along the axial direction can predict trends in stress distribution and deformation of the large-belt width roller.
