MICROMECHANICAL VIBRATORY GYROSCOPE Russian patent published in 2006 - IPC G01C19/56 

FIELD: the invention refers to the field of high-precision instrument-making industry and may be used at manufacturing of such measuring devices of an angular speed of a moving foundation as vibratory gyroscopes.

SUBSTANCE: the gyroscope has a foundation, an inertial disk attached to the foundation with the help of an inner elastic suspension consisting of four direct elastic rods of rectangular section having length and width equal with the height equal to the thickness of the disk and located radially under equal angles to the axle of sensitivity of the device and attached with the inner sides to the foundation, a system of electrostatic excitement of the vibrations of the disk consisting out of engines of excitement and sensors of angular position; a system of electrostatic pick up of output vibrations consisting of electrodes located on the foundation under the inertial disk, elastic bonds placed concentrically to the disk for reducing expanding efforts and providing necessary angular turn of the elastic rods at their deformation. At that nonlinearity of the primary vibrations is sharply reduced.

EFFECT: provides stability of vibrations, increases exploiting characteristics , maximum sensitiveness of the device.
