Research on the Optimal Design of Driving Sprocket of Coal Mine Scraper Conveyor
Using SolidWorks and ANSYS Workbench software,a finite element model was established and force analysis was carried out according to the actual structural dimensions of the driving sprocket of SGB420/17 scraper conveyor.It is found that the stress and strain concentration phenomenon occurs in the chain nest area of the driving sprocket,and the maximum contact stress and maximum strain are 168.89 MPa and 0.001 14.The maximum contact stress in the chain nest area of the driving sprocket is taken as the optimisation target,and the four main structural dimensions in the chain nest area are taken as the optimisation objects to carry out optimisation and improvement work.The maximum contact stress and strain of the optimised sprocket were reduced by 13.14％and 6.14％respectively,achieving the expected results.The service life of the sprocket wheel can be improved by about 10％through the field test in three months'time.
