Optimised Design of Cut-Off Reducer for Roadheader and Its Dynamic Simulation Analysis
In order to improve the transmission precision and reliability of EBZ160 roadheader,particle swarm optimisation algorithm is used to obtain the optimal solution of the structure volume of planetary reducer,and the optimised volume is reduced by 9.8％compared with the original volume.And the ADAMS simulation study found that:under no-load condition,the reduction ratio of the gearbox is 23.5,compared with the design reduction ratio of 22.5,the transmission error is 4.4％;under constant load torque condition,the average value of the meshing force between the first and second stage sun wheel and the planetary wheel is 1.38 × 105 N,2.23 × 104 N,respectively;under the variable load condition,the maximum force between the first and second stage sun wheel and the planetary wheel are 1.24 × 105 N,2.81 × 104 N,which meet the requirements.
