Gyroscope having liquid metal suspension means
Abstract
Abstract A SINGLE DEGREE-OF-FREEDOM GYROSCOPE IS PROVIDED HAVING ITS GIMBAL SUPPORTED FOR ROTATION BY A PAIR OF FLOATED TRUNNIONS AXIALLY DISPLACED ALONG THE GYRO''S OUTPUT AXIS. THE FLOATS WHICH ARE SOLID AND HOMOGENEOUS ARE SUSPENDED IN FLOAT CHAMBERS FILLED WITH LIQUID METAL UNDER A POSITIVE STATIC PRESSURE. EACH FLOAT IS CONNECTED TO THE GIBAL BY A SHAFT COMPRISING A SPHERICAL CENTER PORTION AND TWO AXIALLY EXTENDING TAPERED SHANK PORTIONS. THE SPHERICAL CENTER PORTION IS CONSTRAINED TO ROTATE WITH THE GIMBAL IN A JOURNAL BUSHING MOU NTED IN A WALL IN THE GYRO CASING WITH EACH WALL SEPARATING THE RESPECTIVE FLOAT CHAM- BERS FROM A CENTRAL CAVITY CONTAINING THE INERTIA-WHEEL GIMBAL ASSEMBLY. BECAUSE OF ITS EXTREMELY HIGH SURFACE IS BY CAPILLARY ACTION PREVENTED FROM ESCAPING THROUGH THE CLEARANCE BETWEEN THE SPHERICAL SHAFT PORTION AND THE BUSHING INTO THE GYRO''S CENTER CAVITY.
