Method for dynamically balancing moving shaft of dynamically tuned gyroscope

Abstract

The invention belongs to measuring and adjusting technology and relates to a method for dynamically balancing a moving shaft of a dynamically tuned gyroscope. A dynamic balancing disc is arranged on a flexible head shaft of the gyroscope, so that a fit clearance between a flexible head installation hole of a bearing shaft of the gyroscope and the flexible heat shaft is enlarged, and a rotating shaft system of the gyroscope moves slightly, so that a shaft system of the gyroscope is in a dynamic balance state. The method has the advantages of perfectly solving the problems of excessively high requirement on processing accuracy and contradiction between dynamic and stationary balances existing in the conventional dynamic balance mode, reducing movable parts on a gyroscope rotor, improving the dynamic balance accuracy and stability of the gyroscope, and effectively enhancing the repetition accuracy and prolonging the service life of the gyroscope.

Description

technical field [0001] The invention belongs to the measurement and adjustment technology, and relates to a shaft-shifting dynamic balance method for a power tuning gyroscope. Background technique [0002] The dynamic balance of the power tuning gyro is to ensure that the gyro obtains a highly stable rotating shaft system, and then provides stable angular momentum. The traditional dynamic balance method is to increase or decrease the mass at the motor end and rotor end of the shaft system to reduce the torque. Balance, there are two problems in the traditional dynamic balance method: one is that the machining accuracy of the motor shaft hole and the shaft of the flexible head is too high; the other is that there will be a contradiction between dynamic and static balance at the rotor end of the gyro, which will affect the static balance of the gyro precision. Contents of the invention [0003] The object of the present invention is to propose a method for moving the axis o...
