FLOATED-TYPE SINGLE-DEGREE-OF-FREEDOM GYROSCOPE Russian patent published in 2004 - IPC

FIELD: precision instrumentation engineering, operation of singe-degree-of-freedom gyros. SUBSTANCE: gyroscope has cylindrical case 2 with two face covers 4, 5, cylindrical float chamber 6 with gyromotor 7 located in case 2 on limiting stone supports 8. Clearance between. case and float chamber is filled with high-density supporting fluid. Transmitter 9 of angle-data of turn and torque generator 10 are positioned on axis OX of suspension of float chamber 6. Bellows 11 is anchored on butt cover 4. Heating winding 12 and winding 13 of temperature-sensitive element are put on outer cylindrical surface of case 2. Thin-walled cylinder 14 is installed in case 2 of gyroscope uniaxially with it. Conduits 15 for transfer of fluid are formed by rectangular grooves made in outer surface of thin-walled cylinder 14, along its longitudinal axis, and inner surface of case 2. Length of cylinder should be such that summary clearance (δ₁+δ₂) between butts of cylinder 14 and inner surfaces of covers 4, 5 is not less than double value of depth h of grooves for transfer of fluid while it is mounted in case. Cylinder is so mounted that size of clearance (δ₁ or δ₂) between each butt of cylinder and inner surface of corresponding cover is not less than depth h of groove for transfer of fluid when covers are installed. EFFECT: increased operational precision of gyroscope. 3 dwg
