Detailed theoretical calculations and eigenvalue analyses of self-excited vibration during slippage of parallel cardan drives were made. The influences of the stiffness and damping of flexible couplings and gearbox suspension rubbers were studied, and the measures to suppress the self-excited vibration were clarified. Experiments on two cases with a leaf spring coupling were made by varying the stiffness and damping of the coupling and the gearbox suspension rubber. The experimental results were confirmed to agree well with theoretical results. Experiments on another case with a gear coupling were also made, and it was clarified that this case generates less vibration. Furthermore, available adhesion coefficients μa were measured for both cases with self-excited vibration and with no self-excited vibration, and it was shown that the latter case can attain larger μa.
