Modelling and Structural Analysis of Planetary Geared Winch

Planetary gear sets are used widely in many diverse product applications. Their compact and co-axial design and gear ratio make them preferable to counter-shaft gear drives. Planetary gear sets are complex, multi-mesh systems formed by multiple stages of planet gears that are in mesh with a sun gear and a ring gear and they are held by a common carrier through needle bearings and planet pins. Their design presents unique challenges stemming from a number of load factors issues, including their planet load sharing behavior, dynamic response, deflections, and support conditions. This study investigates the influence of load factors on gear stresses, and their impact on the resultant bending fatigue lives of the gears in planetary gear sets. These models are made by using part and assembly design module in CATIA V5R20 software, while the analysis is done in ANSYS V14 software. Optimization is based on ANSYS results, which can be used to enhance the efficiency of the design process.
