The assembly of the hinge (Fig. 1) is carried out as follows. Before being assembled in the initial state, the distance between the opposite glasses 6 fixed in the eyes of the fork is somewhat larger than the distance between the glasses in assembled form. One of the pegs 2 is inserted into one of the cups 6, and then the opposite pin is inserted into the other beaker. Due to the increased distance between the cups 6, the rollers 4 are installed into the gap between the working surfaces of one pair of mating (pin-glass) and then into the gap between the working surfaces of the other pair of mating. Then, the tension rod 7 and the nut 10 are installed. The adjustment of the backlash or prestressing of both radial and axial joints 3-4-5 is achieved by means of a larger or smaller screw-on of the nut 10. In this way, an accurate and reliable assembly of a single fork with a crosspiece is carried out. The assembly of the other plug with the cross is similar. In the embodiment of FIG. 11, the assembly and adjustment of the hinge is carried out similarly by means of tie rods 47. In the embodiment of FIG. 3, the direction of the axes X-X of the rollers 4 is invariant relative to the embodiment of FIG. 1 in order to increase the load capacity. The assembly of the hinge (FIG. 3) is carried out as follows. Before installing the cap 16, the crosspiece 13 with the installed cuffs 12 is inserted into the hole 15 of one of the glasses 14 with the corresponding trunnion 2, and then with another coaxial axle 2 into the hole 15 of the other glass 14. The rollers 4 are placed between the working surfaces 3, 5 of one pair (axle glass), then the glasses 14 are brought together by pyrqjrp. Compress the eyes of the reel and install the rollers 4 between the working surfaces 3, 5 of the other pair (pin-glass). After installation of the rollers, the compressive force applied to the to the eyes of the plug, thereby giving, under the action of elastic forces, they return the plugs to the original position, which provides the required prestress in the 3-4-5 connection. Next, install the caps 16, fill the lubricant and install the sealing cuff 12. To precisely adjust the size between the coaxial cups, rods can be installed in a manner similar to that shown in FIG. 2 or FIG. 11 working in compression. The assembly of the other versions of the hinge is carried out similarly to the assembly of the described variants. The operation of the proposed universal joint does not differ from the operation of the known joint, since they are schematically executed similarly. In connection with the implementation of the working surfaces of the trunnion and cup spherical and toroidal shape, with the rolling elements in the form of rollers with a convex or concave curvilinear generatrix of the corresponding radius, with the installation of the axes of the rolling elements at a certain angle to the axes of the corresponding trunnions, as well as with the connection of opposing glasses by means of fixed rods in the proposed cardan joint, the disadvantages inherent in the known joint were eliminated. Thanks to the proposed hinge implementation, it is possible to achieve its service and reduce the labor intensity of manufacturing, in particular, the elastic deformations of the fork lugs and crosses do not affect the distribution of pressure along the contact surfaces of rolling elements with working surfaces of trunnions and glasses due to the choice of the contact surfaces, which results in increased service life ; their rolling elements do not interact with the bottom of the glass due to the choice of the shape of the contacting surfaces, which does not cause overheating, which results in longer service life and reduced labor intensity due to the lack of quality requirements of the ends of the rolling elements and the bottom of the glass; regulation of axial and rational clearances or tension (eg 91145936 in conjunction with performance, in view of constructiveness. the lower possibility of adjusting the axial labor intensity of manufacturing; in the full- and radial clearances in the joints, the opening of the working surfaces of the pins, needles, which results in a reduction in the labor-consuming cups, does not require a high precision of manufacturing ig.g.
