    专利说明:

    The invention relates to the improvement of a centrifugal brake for a gyroscope in cardan gimbal and, in particular, for gyro horizons and direction gyros, which serve to indicate the position of an aircraft relative to its longitudinal and transverse axes and direction line. It is known that when a gyroscope rotor rotates at a nominal speed, the torque that ensures its rotation is equal to the resistivity created by the bearings and air resistance. The rotor axis of this gyroscope maintains an unchanged position in space. If the torque decreases or disappears, either involuntarily in the event of a power failure, or deliberately, when you want to stop the device, the rotor continues to rotate with a decrease in rotational speed due to the resistance shown above. If the rotor axis is not perpendicular to the external axis of the gimbal, then the moment of resistance has a component along the external axis of the suspension, which is applied to the rotor in precession, i.e. in rotation around the internal axis of the suspension, which tends to bring the axis of the rotor closer to the external axis of the suspension. This movement begins in the direction of the initial deflection, it is very slow, but its speed increases. The existence of friction moments around the suspension axes This movement practically begins only if the rotor axis has deviated sufficiently from the perpendicular to the outer axis of the suspension. When this phenomenon occurs, the axis of the po, torus can be aligned with the outer axis of the suspension, unless the stop, usually provided on the inner ring of the suspension, stops this movement, coming in K (H1 contact with the outer suspension ring. In both cases, the precession movement another phenomenon arises and a rotor arises (if it is still rotating.) cTpeMHt with rotational movement of the entire movable part of the gyro around the outer axis of the suspension with a speed which increases. Century forces that can result damage to nixi6opa. A device for preventing these negative phenomena is known; Phenomena, the principle of their operation concludes that when the power supply to the device is stopped, arbitrarily or unintentionally, there is a stop or brake, which O1 reduces rotation around the outer axis of suspension 11 However, this device also limits the ability to control the maneuvering of an object using a gyroscope, while this gyroscope, continuing to rotate by inertia, can still be used for quite a long time in gyro horizons with mechanical correctors, such as ball or mastic. A centrifugal brake for a gyro in a gimbal suspension is known, which eliminates this drawback of blocking the braking of the outer ring of the suspension when the power of the gyroscope stops, while the gyroscope rotates at a speed sufficient to provide control of the changes in the position of the gyroscope 2. In this brake the braking does not depend on the acceleration in the whole, created in the gyro support during the firing of positions, the brake acts when there is a stop to limit the relative movement of both rings ca and when such abutment offline. This centrifugal brake contains at least two inertia Georgians symmetrically located on the outer suspension ring along a circumference, the dent of which is on the outer axis of the suspension, each of these weights associated with the outer suspension ring and can move in a plane perpendicular to the outer suspension axes in such a way as to be able to move with a tray along the inner cylindrical part and thus create a braking effect on the rotation of the outer ring. In t (there is at least one return spring connected with inertial weights and one stop, with the lowering movement of the weights in the direction of the outer axis of the weight. When all the backward weights are fixed in the quiescent position by the stop or / ugors, tension, - created by a spring or springs of a bopee centrifugal forces that are created in the weights by an external outer suspension ring. Toi can only start from the moment when the angular velocity of the outer ring exceeds the predetermined one. The circuit of the invention is simplified This is achieved by the fact that in a centrifugal brake for an outer coyote gyroscope in cardan suspension, mounted in a housing on a movable support containing two identical inertial ameminga, symmetrically installed foamy center on the outer ring of the axis of the outer body. and can be rotated about two diametrically opposite axes parallel to the outer axis of the suspension, each of the inertial elements being provided with a protrusion made with the possibility of its friction against the inner a new cylindrical part of the body when the outer ring rotates, at least one return spring connected to the inertia elements, and at least one stop to limit the movement of the inertial elements in the direction of the outer axis of the suspension, each inertia-like element is made O-shaped with a central part and two peripheral parts, from KOTopsJX one —internal, and the other — external, and in the place of transition of the central part to the peripheral internal part, an emphasis was made in the form of a protrusion, and 1 eplena to the central portion of nogo {inershonnogo element and the other end to the inner peripheral portions prugogr inertial aaementa, FIG. 1 is a brake system, perspective view; Fig, 2 brake, front view, in the rest position; in FIG. 3, the same as in the work set. The proposed system contains an outer lance 1 (shown in part) serving as a support for a centrifugal brake. Centrifugal (03 consists of two inertial elements reminiscent of an identical shape of a CUqua C, opposite symmetrically / fuggdg, N. Inertial elements of the Common part 2 have the central part 2. The inner peripheral part 3 and the outer peripheral part 4. In the central part 2 the protrusion 5 braking against the inner surface of the housing: the inertial elements are mounted yo x 6. The inertial elements are connected by return springs 7 and are supported on the internal stop 8u. Part 2 of the peripheral inner part 3 is provided with a protrusion 9, which is an abutment for the end 1O of the peripheral outer part 4 of the inertia element. The flange 11 serves simply to hold the inertial elements in their plane. The initial tension of the spring 7 fixes the angular speed, at which the protrusions 5 come into contact with the body, causes the occurrence of a frictional moment, which causes the rotational speed of the movable part of the gyroscope. This limited speed is reached when the moment of friction is proportional to the centrifugal force that rests on the inertial elements; : equal to the torque. As a result of the hinged installation of ymtffioe, the movement of one of the inertial elements necessarily causes the Ofyrou element to make an equivalent coal (This movement is a symmetric effect: the arrangement of the hinge axes 6 relative to the XX axis sensitive only to centrifugal accelerations 51M around the axis XX, leaving complete freedom to move the {L part of the pfoscope during various accelerations of the encounters aihs during flight.
