The Geneva Mechanism Motion Simulation and Research to Improve the Design Method

“…(1) When the round pin in the common straight groove driven geneva wheels geneva mechanism, the round pin into and out of the notch, the angular velocity of the driven geneva wheel is zero, but the angular acceleration is not zero, there is a flexible shock, and the maximum value of angular acceleration is high, because of the noise and vibration, limited the speed of the machine and the positioning accuracy. To eliminate the problem of the flexible impact, With the premise of the relation that driven geneva wheel and the rotation angle of round pins remain unchanged, and the pressure angle under the available range, design a new curve groove of the driven geneva wheel, that is a straight line contour of driven geneva wheel changed to the high-order polynomial or a sine curve [5,6], as shown in Figure 6.…”
