Compared to the ratchet mechanism The Geneva mechanism has no rigid impulse and motion is smoother. Geneva mechanisms can be used to drive rotating tables with large moments of Inertia The angular velocity of a geneva mechanism should not be too high. The rotation angle of a geneva wheel for each cycle can not be adjustedCompared to the ratchet mechanism The angular velocity of a geneva mechanism should not be too high.
