Strength Analysis on Propel Gearbox of Hydraulic Excavator

Abstract

Taking the external load distribution on sprocket wheel and meshing forces of planetary gear trains into account， the strength of case and the three-stage planet carrier assembly under three working conditions is analyzed by using Abaqus， comparison and analysis of three solutions of planet carrier and pins structure is carried out， and the accuracy of the FEA result is confirmed， which provides the basis for subsequent design and manufacture.
