Structural Improvement and Application Research of Coal Mine Belt Conveyor Drive Roller
Analysis and research on the structure of the drive roller of DTL160 belt conveyor,combined with the actual use of finite element analysis software ANSYS to analyse the fatigue life of the roller,and found that the fatigue life of the middle area of the cylinder of the drive roller is the weakest,and measures need to be taken to improve the life of the middle area of the cylinder.Setting a support ring in the middle area of the transmission drum can effectively improve the strength and stiffness of the drum,by changing the width of the support ring for research and analysis,and finally determine the width of the support ring for 5 mm.the research will be applied to the transmission drum structure in the coal mine engineering practice to verify the application of the observation and records,found that the new transmission drum has a good operational stability,the technical personnel assessment that the service life can be extended by more than 20％,which can provide a good solution for the coal mine.The technical personnel assessed that the service life can be extended by more than 20％,which creates good economic benefits for the coal mine enterprises.It can provide a reference for improving the performance of belt conveyor drive roller in coal mine and enhancing the stability and safety of equipment operation.
