Study Of Disturbance Response For The Electromechanical Integrated Toroidal Drive

Electromechanical integrated toroidal surface transmission is a new kind ofgeneralized composite transmission mechanism, and it is derived from electromechanicstheory combined with toroidal planet worm drive, which has many outstanding advantages,such as compact volume, less wear, large range of transmission ratio and torque. Due tothe disturbance produced by the extrinsic motivation, some effects may happen on thesystem. That is the significance and worth for the analysis of electromechanical couplingdynamic disturbance. The followings are the main contents of this research:A model of electromechanical integrated toroidal surface transmission mechanism isbuilt. Considering the process of meshing, alternating of meshing gear logarithm producesstiffness motivation, dynamic differential equation is established. Using numerical methodto affects impact of meshing stiffness on the system is analyzed. Considering the currentexcitation of planet wheel, inductance, ratio a/r, transmission ratio between planet wheelsand the change of planet wheel mass separately, meshing stiffness can have effect on thesystem vibration response.Due to the fluctuations in the rotor inertia incentives, when the number of planetwheel change is different, the wave amplitude of rotational inertia, the current excitationof planet wheel and the mass of planet wheel is changing; all of those can producedifferent effects on the system vibration response. Meanwhile, the effect of meshingstiffness and fluctuations in the rotor inertia incentives on the stability of system is acompared.During the analysis of electromechanical integrated toroidal surface transmissionsystem, a differential equation of meshing stiffness and rotational inertia is built. On thebase of system stability analysis, the results of effects on the system due to the changing ofthe parameters of the wave amplitude of rotational inertia, the current excitation betweenrotors and stators of planet wheel and the mass of planet wheel are got.Through analyzing the results of prototype changing in the experiment when thesystem is disturbed by the electricity, we compared the results of the theory with the result of the analysis.
