Structure Optimization And Remanufacturing Of Roller For Belt Conveyor

Along with the new development of the bulk material, belt conveyor as an important equipment of transportation industry, put forward some new requirements: high speed, long distance, large throughput, intelligent and low probability of accidents, however, roller as an important bearing and transmission parts, its structure reliability and the quality of high quality obtain more and more attention, remanufacturing the failure roller in a timely manner, have a direct impact on the overall performance and security of the belt conveyor.First, by learning a lot of study and research on the roller conveyor of information, classify, rollers are different categories, and the composition of the various components of the roller for a detailed structural design calculations, based on the traditional roller structure,design new cantilever type of roller, using ANSYS software establish each of these two structures cylinder model, mesh, add constraints,applied load,static calculations,find the maximum stress and the maximum deformation displacement,and check the data,grasp the basic of the roller force and deformation; the roller static characteristics have been significantly improved; compare the view of stress and deformation conditions, adopt corresponding remanufacturing technology to repair, Making the structural design of the roller more secure.Second, the optimal design of the roller structure, the structure and size of the roller has a serious impact on the overall weight of the roller, the roller for the new cantilever type proposed in this paper. Using of finite element analysis, carried out on the roller-objective optimization, select three variables to optimize, the total mass of the roller as the objective function, under the strength and the stiffness of the premise, to achieve the ideal of optimization results and lightweight roller, contrast before and after optimization, realizing lightweight, under the premise of the stiffness of structure strength, reach the ideal optimization results, at the same time Modal analysis was carried out to determine the vibration characteristics of the structure, to understand the natural frequency of the different modal, have a great significance on actual production.Finally, introducing the re-manufacturing repair technology, As the bearer of the components, Because of the different structures and load conditions, roller is susceptible to damage, summarizes the various failure modes of the roller, for each failure mode, and then take the appropriate manufacturing technology to repair and improve the performance of the roller and belt conveyor, to prolong the using life.
