    摘要: The present invention relates to a small nominal diameter oval gear flowmeter having curved swivel surfaces for automatic self-alignment of the oval gears about a longitudinal shaft axis to enhance measurement accuracy and facilitate restriction-free rotational movement of the oval gears by reducing gaps in the seal surfaces to prevent contact between the oval gears and the axial measuring chamber wall. Two or more oval gears are each supported on independent shafts which in turn are supported in the measuring insert of the housing. The oval gears are supported on the shafts in such a manner that they may swivel at a small angle about the longitudinal shaft axis and that small axial displacements of the oval gears may be accommodated on the shafts. A plurality of recesses that reduce the support length to approximately the shaft diameter are located on both sides of the frontal surfaces of the oval gears, to provide for automatic alignment of the oval gears. In accordance with an alternate embodiment, curved surfaces are provided either on the shafts disposed through the longitudinal bore of one or more oval gears or on the surface of the longitudinal bore of one or more oval gears, thus allowing a small swiveling action about the longitudinal axis of one or more shafts.

    摘要: 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.

    摘要: The invention concerns a permanent magnet front or central coupling unit that generally works through a watt to transfer measured values and torque in units that may, for example, be used in the volume gauge technology. In accordance with the task, the permanent magnet coupling shall be designed so that its transferable maximum torque is not present in the starting state and that it thus exhibits vibration-damping properties. In accordance with the invention, this is achieved by the fact that one or several permanent magnets are arranged in a fixed manner and that the poles are located such that they produce repulsive forces in their effective direction, i.e., the respective opposite magnet poles are of equal denomination. In the stationary state, the magnet poles thus occupy the greatest possible distance from each other, resulting in the lowest possible transferable torque. As a function of the required load, the coupling halves begin to rotate and the transferable torque increases to the required value. The coupling thus exhibits vibration-damping properties.
