Research on the Optimisation of Scraper Conveyor Sprocket and Round Sprocket Structure
In order to optimize the structural dimensions of scraper conveyor sprocket and round sprocket,numerical simulation software is used to model the round sprocket and sprocket,and the modelling process is given,which lays the foundation for the subsequent simulation calculation.The stress and strain of the round sprocket and sprocket wheel are analysed under the working condition,and it is found that the stress and strain of the structure are mainly concentrated in the contact position of the circular chain and the chain ring at the engaging end as well as the contact position of the sprocket wheel and the circular chain at the chain nest position,with the maximal stress being 122 MPa and the maximal strain being 0.007998 m.The optimization of the structural dimensions is carried out through MATLAB,and the optimized thickness of the short tooth is 35 mm,and the length of the chain nest is 64 mm.The radius of the tooth arc is 22 mm,the arc length of the chain nest is 20 mm,and the diameter of the round sprocket is 12 mm.After the optimisation,the maximum stress and strain are reduced to 0.001074 m respectively,and the maximum stress is 72.3 MPa,while the structural mass is reduced by 50.5％,and the overall optimisation is more successful.
