GYRO ROLL SENSOR Russian patent published in 2005 - IPC

FIELD: gyroscopic equipment, applicable in gyros for stabilization of the vertical direction.

SUBSTANCE: the roll sensor has a gyro in a cardanic suspension and a system of horizontal correction with correction motors and liquid pendulum sensors, whose central contacts are connected to one of the phases of the supply voltage, and the output contacts - to the inputs of the respective windings that control the correction motors, the midpoints of the control windings are connected via adjusting resistors to the other corresponding phase of the supply voltage, used additionally are two programmed timers and two actuating relays, the control winding of the first actuating relay is connected to the output of the first timer, and that of the second relay - to the output of the second timer, the breaking contact of the first relay is series-connected to the adjusting resistors, and the making contacts of the second relay are connected in parallel with the respective adjusting resistors, and the inputs of the timers are connected to the phases of the supply voltage.

EFFECT: prevented self-excited oscillation of the gyro unit of the roll sensor without selection of the liquid pendulum sensors or their turning, and reduced time of the readiness of the roll sensor.
