Abstract
A vibration drive assembly comprising two rotary servo motors and an electronic motor controller electrically coupled to the servo motors and configured to regulate the motors and operate them in synchronism with one another at a predetermined rotational speed. Two articulated drive trains are connectable between the servo motors and mold assembly vibrator shafts of a concrete product molding machine and are configured to mechanically transmit rotational motion from the servo motors to the vibrator shafts when the mold assembly is in an elevated vibration position with the vibrator shaft axes coaxially aligned with rotational servo motor axes. The drive trains remain connected between the servo motors and vibrator shafts when the mold assembly is in a rest position below the vibration position, with the vibrator shaft axes axially mis-aligned with respect to the servo motor axes.
