Improved Design of Mining Belt Conveyor Rollers and Verification of Results
In order to reduce the stress and deformation at the centre of the belt conveyor tube and achieve its smooth operation,we propose to improve the design of the rollers by welding a web plate in the middle of the tube through the construction of a simply supported beam model,and the maximum stress and deformation of the tube are reduced by 53.4％and 41％respectively,compared with that before the improvement when one web plate is welded,and the strength and rigidity of the web plate meet the requirements;we also make a further comparative analysis of the maximum stress and deformation of the tube after welding 1-5 web plates.And further compare and analyse the maximum stress and deformation of the tube body after welding 1-5 web discs,when the number is 5,the reduction is very low,but increasing the number of web discs will increase the quality of the rollers and the production cost,therefore,the number of web discs is 1 or 3,the best effect.
