Paper Title:
Dynamical Formulation and Analysis of Double Crank Ring-Plate-Type Pin-Cycloidal Gear Planetary Drive
  Abstract

On the assumption that the ring-plate and gear case as rigid body, taken into account the influence of arm bearing and support bearing’s stiffness, and the distortion of gear at meshing, paper built a dynamical model for double crank ring-plate-type pin-cycloidal gear planetary drive, calculated the meshing stiffness for the involute gear and the pin-cycloid gear by program, based on Newton second law, a 33-DOF dynamical model include input and output shaft, ring-plate, involute gear and gear box was formulated by lumped-parameter method, obtained the natural frequency and vibration character for the system with bending and torsion coupling working condition, calculate results show that between 600-800Hz and some other frequency bands the system my easily cause resonance when input shaft turning at 1500r/min, which was approximately match with the prototype vibration test. For the problem that the first prototype has obvious oscillation and noise, improvement method about reinforce the gear case stiffness, increase the first transmission ratio and enlarge the output shaft stiffness was applied, theory analysis show that this measures may better decrease the vibration and noise for this kind of new drive.
