The optimization design of planetary reducer for shearer cutting unit is carried out. The optimization model of planetary gear reducer is established by method of lightweight and constraint condition, and the solution is obtained by MATLAB software.The results show that the total volume of the planetary gear reducer is reduced by 21.34% and external diameter reduced by10.15%. This shows that the method is more obvious to reduce the volume and weight and the method greatly improves solving efficiency.
