Strength Analysis and Lightweight Design of Spoke Plate Hub of Mining Belt Conveyor Drive Pulley
Taking DTL140 belt conveyor drive pulley commonly used in coal mines as the research object,after analyzing its structural composition,the finite element model of the drive pulley is constructed by SolidWorks and Ansys software,and the strength analysis is carried out.The calculation results show that the maximum stress value of the spoke hub of the drum is much lower than the permissible stress value of its material,156 MPa.In order to save the manufacturing cost of the equipment and avoid the redundancy of the structure,the spoke hub is designed to be lightweight by punching.Finally,through the strength comparison,it is found that when the number of holes is 8,the maximum stress value is 142.42 MPa,and when the number of punched holes is 9,the maximum stress value is 160.1 MPa.Therefore,the number of punched holes is set at 8 as the final design result,which realizes the lightweighting of the structure under the prerequisite of guaranteeing the safety standards and achieves the purpose of"cost reduction and efficiency enhancement".The purpose of"cost reduction and efficiency increase"is achieved.
