    This goal is achieved due to the fact that in the device for determining the angle of rotation of the moving mechanism, which contains a movable holder rigidly connected to the mechanism, the angle of rotation sensor associated with the output transducer has a fixed holder associated with the fixed base of the mechanism. mobile
     the cage is an annular hermetic cavity in which the rotation angle sensor is located, connected through a coaxial rotating element with a movable holder ..0 Angle angle sensor. And the rotating element is made in the form of a cam, connected to the movable holder by means of a corrugated spring washer, and elements of the output transducer placed on the outer side of the fixed cage, through the hole made in: the cylindrical wall of the fixed cage, are placed in the plane of the cam movement, and on the cam surface and inside on the morning surface of the fixed ring, retaining protrusions and grooves are made. In addition, a planetary gear is located between the movable yoke and the rotation angle sensor in the annular sealed cavity, the planetar to the gear which is connected by an eccentric bearing ring with a movable yoke, the planetary gear made with two toothed crowns with different pitch circle diameter and gear ratio, the first a gear rim is connected with a gear rim of an annular gear with internal teeth fixed on a fixed holder; a second gear rim is connected with a coaxial rotary gear The element, which is the central wheel of the planetary gear, and the central wheel of the planetary gear set with the possibility of a dead-weight and fixed gear. me . At the same time, the bearings are mounted between the clips and the flame is extinguished. Figure 1 shows the movable and fixed cage assembly; Fig. 2 shows an embodiment of a device with a flame-damping gap; FIG. 3 shows a device with a rotation angle sensor in the form of a cam mounted in an annular space between the sleeves and interacting with an output transducer, top view; figure 4 - output Converter, one of the options; figure 5 is a variant of the device with a planetary gear, the top view of figure 6 is the same, side view. The specific object on which the device is installed determines how many parts it will consist of in finished form. It is essential that after assembling the two annular parts (movable and fixed casing) are stacked on each other and form between them the annular space. These parts — the fixed holder 1 and the movable holder 2 fixed on it — are shown in FIG. 1, and bearings 3 are installed to ensure their twisting together, and a seal 4 can be installed to protect it from moisture. as well as to ensure safety from external overpressure between the clamps, a flame damping gap 5 is made with a seal 4 therein. The device (fig.Z) also contains a wheel b fixed on a fixed holder 1 with a locking groove. On the outer side of the yoke 1 there is a closed housing 7 in which the output converter 8 is installed, which can be made in the form of microswitches 9, actuated by the lever 10. The lever 10 is the receiving element of the output converter 8 and receives through hole 11 in the cylindrical wall 12 of the fixed casing 1, the movement of the angle sensor. The rotation angle sensor and the rotating element are a cam 13 connected through a corrugated spring washer 14 to a movable holder 2 rigidly connected to the mechanism, the angle of rotation of which is determined. The fixed holder 1 is connected to the fixed base. The corrugated spring washer 14 uses a friction force to create a guaranteed tension between the yoke 2 and the cam 13 located in the annular sealed cavity 15. The cam 13 is provided with a stopper 16 for engaging a groove on the wheel G. The device according to the embodiment shown in FIG. 5 and b, contains a movable cage 2, a fixed cage 1. A planetary gear train consisting of an annular gear 17 (6) with internal teeth of a planetary gear with two toothed gear wheels 18 is placed between the movable casing .1 and the angle-of-turn sensor. and 19 and a coaxial rotatable element 20 with a gear teeth with internal teeth, which is the central wheel of the planetary gear. The planetary gear with rims 18 and 19 is rotatably mounted on the eccentric ring 21 of the bearing. The eccentric ring 21 is rigidly connected to the movable yoke 2. The first gear crown 18 of the planetary gear meshes with the ring gear 17, which is connected to the stationary yoke. 1. A second gear ring 19 is connected to the ring gear of the central wheel 20 of the planetary gear. The central wheel 20 of the planetary gearing can be rotatably mounted on the fixed casing 1. The element transmitting the movement to the steering angle sensor is the central wheel 20 connected by means of a corrugated spring washer 14 with a cam 13 having a protrusion 22. The lug 22 interacts with the arms 10. In the fixed casing 1, grooves (apertures) 11 are made in which interchangeable stoppers 23 are fixed to rest on the protrusion 22 to indicate the end position. On the other side of the protrusion 2 a protrusion 24 for the indi The initial position of the moving mechanism.
    In the considered variant, the angle between the two positions of the mechanism at one revolution is about 350 and to this is added the total number o6ppOTOB, corresponding to the value of the transfer ratio of the planetary gear transmission. ..
    Us1 | groystvo (figs. 3 and 4) work as follows.
    When rotating the movable casing 2 associated with the movable mechanism, the cam 13 acts on the lever 10 of one of the microswitches 9. In the example shown, the angle of rotation is determined from the initial position of the movable mechanism to its final position and makes a groove 90 A groove on the wheel it is intended for stopping the cam 13 by the stopper 16 when the profile of the cam 13 is pushed onto the lever 10.
    The device (6) works as follows.
    The eccentric wheel 21 rotates with the movable yoke 2.
    and presses the gear wrenches 18 and 19 to the ring gear 17 and the centrifugal wheel 20. Since the diameter of the separating circle and the front gear ratio of the planetary gear rims are different, the wheel rotates depending on the difference of these values. For example, if the difference in the number of teeth of both crowns is, for example, 129 - 125 - 4, then the turn of the wheel
    20 with the turn of the movable casing 2 corresponds to the arc of 4 in a tooth. At this time, the cam 13 is rotated in accordance with the rotation of the wheel 20.
    The angle between the two positions of the mechanism can be adjusted using a permutation of the rims 18 and 19, the eccentric ring 21 and the rotation of the wheel 20 relative to the fixed
    clips 1. Instead of a planetary gear in the device, a gear or a worm gear with interchangeable elements can be used. Angle sensors can be made
    in the form of inductive, capacitive
    or pneumatic sensors.
    one .
    The proposed design makes it possible to make the device for determining the angle of rotation more versatile, technologically advanced and, therefore, cheaper.
