METHOD OF REGULATION OF DYNAMICALLY ADJUSTABLE GYROSCOPE BEING PART OF GYROSTABILIZER, DYNAMICALLY ADJUSTABLE GYROSCOPE Russian patent published in 1998 - IPC

FIELD: gyroscopy. SUBSTANCE: adjusting member is introduced into dynamically adjustable gyroscope with nonrotating shaft. This element provides for formation of zones in gyroscope with nonrotating shaft. This element provides for formation of zones in gyroscope of two different pressures P₁ in zone A surrounding the rotor and P₂ in zone located beyond zone A. Then pressure P₁ is created in zone A which is less than P₂ by at least four orders, controllable component of speed of dynamically adjustable gyroscope departure is determined within single-axle gyrostabilizer, pressure in zone A is increased up to P₂ level. Then creation of different pressures P₁ and P₂ and subsequent operations are repeated up to zeroing of departure speed controllable component. This done, adjusting element is removed from gyroscope. Device intended for given method realization has rotor with flexible suspension positioned on shaft by means of two bodies provided with coaxial axes of shaft rotation and having corresponding cylindrical projection and groove. Groove depth exceeds projection height. Metal shim made of flexible material, for example of indium, is installed in groove as adjusting element. Formation of two zones of different pressure P₁ and P₂ in adjustment enhances stability of bearing vibration condition considerably (due to high P₂) and reduces rotor oscillation damping (due to minimum P₁). As a result, vibration component of departure speed depending on acceleration is removed with increase of gyroscope sensitivity. EFFECT: enhanced accuracy of adjustment. 2 cl, 2 dwg
