Research on Load Sharing Characteristics of Compound Planetary Transmission System Considering Meshing Error
In order to study the load sharing characteristics and factors affecting the load sharing character-istics of a compound planetary transmission system,a gear stiffness solution model was established using the potential energy method,and the time-varying meshing stiffness of the transmission system was solved;Tak-ing into account factors such as damping,time-varying meshing stiffness,and meshing error,a translation-torsion coupling dynamic model of the system was established using the lumped mass method.The New-mark-β the integration method solved the dynamic response of the system,quantified the load sharing per-formance with a load sharing coefficient,and analyzed the effects of rotational speed,load,and eccentricity errors of single and multiple components on the load sharing performance of the system.The analysis results indicate that increasing the speed will reduce the system's load sharing performance,while increasing the load will improve the system's load sharing performance;An increase in eccentricity error will reduce the load sharing performance of the system.When eccentricity error simultaneously acts on the internal meshing components,it will reduce the load sharing coefficient by 3.1%;When the eccentricity error of similar planetary gears acts on the center of rotation,it will effectively reduce the impact of the eccentric error on the system's load sharing performance.
