FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of precision instrumentation and can be used in designing and manufacturing of two-stage float-type gyroscopes with gas-dynamical suspension of a gyrorotor. In the known method of balancing the gyroscopic chamber, two-stage float-type gyroscope is mounted on fixed base in a position, at which the output axis of the gyroscope is horizontal, and the axis of rotation of the gyrorotor is vertical. Then, the heat setting system and feedback system are turned on, the gyroscope is heated to the operating temperature and the current in the feedback-torque sensor circuit is measured. Then, balanced weights placed on the end of the gyroscopic chamber are moved along the axis of the parallel measuring axis of the gyroscope; unfold the gyroscope around the output axis by angle of 90°; the current in the feedback-torque-sensor circuit is measured; move the balanced weights installed on the end of the gyroscopic chamber along axis parallel to the axis of rotation of the gyrorotor. In this case, before to start of balancing, the gyroscope is set to a position at which its output axis is vertical, the current in the feedback-torque-sensor is measured, and with the horizontal position of the output axis and the axis of rotation of the gyrorotor after a turn by 90° further unfold the gyroscope around the output axis by an angle of 180° in the same direction, the current in the feedback torque sensor circuit is measured. Then, the average value of the current in the feedback torque sensor circuit is calculated with horizontal positions of the output axis and the axis of rotation of the gyrorotor, and the movement of the balanced weights along the measuring axis of the gyroscope and the axis of rotation of the gyrorotor is performed, respectively, until the value of the current measured at the vertical axis of rotation of the gyromotor rotor is not be equal, and the average value of the current determined at the horizontal positions of the output axis and the axis of rotation of the gyrorotor, with the value of the current measured at the vertical position of the output axis.

EFFECT: technical result is an increase in the accuracy of balancing the gyroscopic chamber of a two-stage float-type gyroscope with gas dynamic suspension of the gyrorotor.
