The three-shafts transmissions can be considered as being elastic systems of joint bars of different lengths, sections, and specific weights. During functioning (spinning), due to its own weight or to some technological deviations of execution and assembling will appear vibrations maintained by the bending. These maintained vibrations frequently lead to get the resonance regim, when oscillations amplitude grow leading to the deterioration or destruction of the cardanic transmission. This paper presents an mathematical model for calculating the pulsation and vibration modes at bending from three-shafts transmission.
