A Study on the influence of sun gear misalignment on planet load sharing and lifetime of planetary gear using MSC.ADAMS
Misalignment on sun gear in planetary gear is easily occurred and it usually causes serious problem of work efficiency and lifetime with the change of planet load sharing.For study on the influence of sun gear misalignment on load sharing,multibody dynamics simulation is employed in this paper.First of all,3D geometry model of planetary gear is built by Solidworks.Based on 3D model,multi-body dynamics model of planetary gear is built by MSC.ADAMS and calculate meshing forces between sun gear and planet gears with each type of sun gear misalignment which are angular,radial and axial type.Based on this meshing force result,load sharing factor is calculated and the results of influence of each misalignment type to load sharing factor is obtained.Finally,gear lifetime is estimated by AGMA gear fatigue strength estimation method with load sharing factor.According to the results,radial misalignment is the most influence to load sharing factor and gear lifetime.
