Abstract EN
For RV reducer widely used in robots, vibration significantly affects its performance.
A lumped parameter model is developed to investigate free vibration characteristics without and with gyroscopic effects.
The dynamic model considers key factors affecting vibration such as involute and cycloid gear mesh stiffness, crankshaft bending stiffness, and bearing stiffness.
For both nongyroscopic and gyroscopic systems, free vibrations are examined and compared with each other.
Results reveal the specific structure of vibration modes for both systems, which results from symmetry structure of RV reducer.
According to vibration of the central components, vibration modes of two systems can be classified into three types, rotational, translational, and planetary component modes.
Different from nongyroscopic system, the eigenvalues with gyroscopic effects are complex-valued and speed-dependent.
The eigenvalue for a range of carrier speeds is obtained by numerical simulation.
Divergence and flutter instability is observed at speeds adjacent to critical speeds.
Furthermore, the work studies effects of key factors, which include crankshaft eccentricity and the number of pins, on eigenvalues.
Finally, experiment is performed to verify the effectiveness of the dynamic model.
The research of this paper is helpful for the analysis on free vibration and dynamic design of RV reducer.
