GYROSCOPE Russian patent published in 2007 - IPC G01C19/02 

FIELD: the invention refers to the field of measuring technique namely to gyroscopic transformers of angular speed with two-stage elastic suspension of a sensitive element.

SUBSTANCE: in the gyroscope with elastic suspension providing dynamic tuning a unit of two-stage elastic suspension consisting of two units of one frame suspension is fulfilled out of high-strength elinvar with high module of elasticity and small temperature coefficient of linear expansion. On the end faces of its units there are grooves matching at assembling. The constant magnets are fulfilled of segments out of rare-earth metal alloy and are hermetically covered with a cowl. The shaft of the drive is fulfilled out of two parts displacing at assembling progressively to each other in the radial direction to the axis of the shaft with the aid of a lever leaning on the stop of one part of the shaft and passing through a window in an arbor. The bar in the collet of the unit out of two-stage elastic suspension is fulfilled out of alloy W-Ni-Co having the temperature coefficient of linear expansion close to the temperature coefficient of linear expansion of beryl bronze out of which the collet with four springs is fulfilled. The flywheel of the unit of the rotor of the gyroscope is fulfilled out of alloy Fe-Co with high induction of saturation in weak magnetic fields. The balancing arrangement is fulfilled as one element with the flywheel in the shape of corbels with lugs. The gyroscope details are fulfilled preliminary prepared for providing balanced condition of the gas medium in the gyroscope cavity filled with hydrogen under pressure of 4-20 mm of mercury column.

EFFECT: increases accuracy of measuring of an angular speed, increases the diapason of measurements, miniaturization of the construction.
