FIELD: realization of hanging of floats of hydrodynamic gyroscopes.
SUBSTANCE: methods of hanging are used in short-time signal reading when gyros are used as angular displacement meters of dynamic objects to be controlled. Methods of hanging of sensitive member of hydrodynamic gyro combine the approaches given below. According to the first approach, the elements of classical hydrodynamic hanging are combined with mechanical device for preliminary centering of float as well as with sensitive member floatation stabilization modernized device; inertial mass is disposed inside inner cavity which mass rotates in rapid bearings by means of frequency starting according to the principle of sync electric motor. Mode of stopway of suspension is provided during process of measurement of parameters of angular movement. According to the second version, shortened rests are removed automatically due to liquid hydrodynamic pressure forces at axial direction from area of angular and reciprocal motions of float of sensitive member; inertial mass is disposed inside internal cavity of the float which mass rotates in rapid bearings. Mode of stopway of suspension is provided during process of measurement of parameters of angular movement. Suspension of sensitive member of small-sized hydrodynamic gyro is realized with preset precision (time constant) to keep to contact-free position relatively the base during short period of time while the base moves at radial and axial accelerations.
EFFECT: improved precision.
