FIELD: measuring instruments.
SUBSTANCE: invention may be used for inspection of the stiffness of gas-dynamic bearings in the course of fabrication and operation of gas-supported precision instruments. The method includes rotating a gyroscope rotor at a working speed and measuring a rotor rotation speed, at which the rotor enters into contact with non-rotatable parts of the bearing under rundown conditions and determining the stiffness from a formula. The rotor rotation speeds, at which the rotor enters into contact with non-rotatable parts of the bearing, are measured in order to detect uneven stiffness of the bearing.
EFFECT: improving the accuracy of inspection and simplification of the method.
