    • A process and apparatus for measurement of nonuniformity of mass of a gyro rotor having a single bearing. The gyro rotor, which is mounted in a radially fixed and spherically yielding pivot, is rotated to a predetermined speed. The static imbalance of the rotating rotor is then determined by measuring the magnitude and angular position of excursion of the rotating rotor. A force couple acting on the gyro rotor and drift of mass of the gyro rotor are determined by sensing movement of a surface of the rotating rotor at two different times. Preferably, the determination of static imbalance, force couple, and drift are obtained in a single course of measurement. After the preceding have been measured, the components of a mass balancing operation for correcting the measured nonuniformities are determined.
    • 用于测量具有单个轴承的陀螺仪转子的质量不均匀的过程和装置。 安装在径向固定和球形屈服枢轴中的陀螺仪转子旋转到预定速度。 然后通过测量旋转转子的偏移的大小和角位置来确定旋转转子的静态不平衡。 通过感测旋转转子的表面在两个不同时间的移动来确定作用在陀螺仪转子上的力耦合和陀螺仪转子的质量漂移。 优选地,在单个测量过程中获得静态不平衡,力耦合和漂移的确定。 在测量前述之后,确定用于校正测量的不均匀性的质量平衡操作的分量。
