专利汇可以提供Balancing system for a rotating mass专利检索,专利查询,专利分析的服务。并且Three different types of unbalance are detected and corrected while a gyroscopic inertial flywheel is continuously spinning. The gyroscope is mounted in an integrated test and correction apparatus comprising an angularly positionable mount supported on a shaker table. The mount supports a test chamber in which the spinning gyroscope is located in a low viscosity, low density atmosphere. Windows are formed in the chamber on opposite sides permitting lasers fixed on the mount to be aimed at the flywheel to burn off selected portions of its mass. A safety system is arranged within the chamber to detect whether the spot at which a given laser beam is aimed has already received a laser burn. Mass unbalance is determined, with the spin axis polar, by rotating the gyroscopic reference axes 90* and recording the drift at two orientations. Radial unbalance is determined by imparting a reciprocating motion along the spin axis by means of the shaker table at the same rate as the rotation of the flywheel. By shifting the phase of the vibratory motion relative to the rotation of the flywheel, a maximum signal proportional to the radial unbalance is sensed by one of the gyro pick-offs. Modulation is determined directly by detecting the amplitude of a modulating signal on the pick-off signal. An automated closedloop procedure determines the correct pattern of laser burns on the flywheel to minimize the unbalances.,下面是Balancing system for a rotating mass专利的具体信息内容。
