VIBRATORY GYROSCOPE Russian patent published in 2016 - IPC G01C19/56 

FIELD: instrument making.

SUBSTANCE: invention relates to navigation equipment, namely to design of micromechanical vibration gyroscope. Vibration gyroscope has a disc rotor in an elastic suspension spring connecting a rotor with fixed support, and stators with electrodes of torsional oscillation drive rotor and capacitive sensors for determination of its angular displacement relative to two mutually perpendicular axes, orthogonal to the axis of torsional vibrations of the rotor. Rotor, spring and support are made of one plate dielectric material with electroconductive coating, the spring connects outer part of the rotor with fixed support and is made in the form of quadruple spiral with limited turn turns at an angle approximately equal to α=π(1±0.2). In the central part of the rotor, free from electrically conducting coating, there is a hole with 2n (n=2, 3, 4…) teeth to interact with 2n electrodes torsional oscillation drive.

EFFECT: high accuracy and simplified manufacturing of vibration gyroscope.
