Abstract
AbstractDouble Satellite planetary gearbox is part of the complex mechanisms with mobile axis. These gearboxes are mainly used in the mining and metallurgical industries, when to operate equipment using hydraulic motors with speeds lower than electric motors, torques transmitted respectively higher gear ratios. This paper presents elements of kinematics and design of the planetary gearbox with double satellite, respectively 3D modeling and its dynamic analysis using the Dynamic Simulation module from the Autodesk Inventor Professional application. Dynamic simulation involves transforming the 3D model of the gear into a mechanism, modeling the kinematic torques, defining the parameters of the driving movement and external loads, respectively visualizing in graphical form the kinematic and kinetostatic results for the different components of the mechanism, in real operating conditions, during a kinematic cycle. At the same time, based on the obtained results, the analysis by the finite element method of the component elements is presented at the time step in which their stress are maximum.KeywordsPlanetary mechanismDegree of mobilityCentral gearSatelliteMechanism analysis
