Abstract
A stabilizing apparatus is provided for use with an oval gear meter. The oval gear meter for receiving material such that the quantity of material is measured by the meter. The meter having the characteristic of alternating acceleration and deceleration for a constant flow of material passing through the meter due to the eccentricity associated with the elliptic shape of the oval gear thereby causing excessive instability or oscillatory conditions with respect to the measured material. The stabilizing apparatus includes a first actuator secured to and synchronized rotationally with an oval gear. The first actuator receives rotational force from the oval gear representative of the quantity of material passing through the meter. A second actuator secured to and synchronized rotationally with a shaft. The second actuator is rotationally driven by force received from the first actuator for transferring rotational force to the shaft. A damping member in operative association with the first and second actuators such that the alternating acceleration and deceleration due to the eccentricity associated with the elliptic shape of the oval gear is smoothed to prevent excessive correction, instability or oscillatory conditions in the measured material.
