Optimal Design of 2K-H Type Two-Stage Epicyclic Gear Train

Total transmission ratio of epicyclic gear train is distributed optimally according to diameter size coordination and equal contract strength of external gearing, and optimal design of two-stage epicyclic gear train is transformed into optimal design of single-stage epicyclic gear train. The volume sum minimum of sun gears、epicyclic gears and internal gears in various stage is regarded as optimal objective, and optimal mathematical model is established. An optimal mathematical model is solved by using the complex method, and optimal parameter scheme is selected.A satisfied result is obtained by means of example computing.
