The stiffness of the planetary carrier directly influences the transmission quality of shearer.The ANSYS-Workbench software of finite element analysis is used to analyze the stress and strain of some shearer＇s planetary carrier.According to the analysis result,the partial construction of the carrier is optimized.The adopting stepped joint on the carrier＇s outlet mitigates the sudden change of stress,and the proper increase of the roundlet radius on the transition joint decreases the concentration of stress.
