A gyroscope with a rotor which rotates about a nonrotating axis is simple in its structure and has but a few movable parts because the rotor axis (2) is divided into two sections by an articulation piece (8), whereby one section (2a) is connected with the housing (11) and the other section (2b) is tiltable about the articulation piece and carries the bearing axis (13) for the rotor (5). The articulation piece (8) is arranged approximately in the center of gravity of the rotor (5). The gyroscope (10) may be constructed to have one or two degrees of freedom and it may be equipped with the measuring device necessary for its operation as a displacement gyroscope or as a rate gyroscope. For a measuring operation in which the rotor (5) is driven only for the uptake, a compensating circuit is provided with an amplifier (23), a servo-control (24), and a multiplier (25) for producing a measured signal proporational to the measured quantity independently of the r.p.m. of the rotor (5). The gyroscope (10) may be driven by a spiral spring (16), electrically or pneumatically. Besides an electrical captivation, a rigid or soft captivation of the rotor axis (2) is also possible. |
