    A quick release clutch coupling for coupling two flanges between which torque is transmitted. Each flange carries a pair of axially extending clutch elements, each of which has bearing surfaces so that the clutch elements of opposite facing flanges engage each other along the bearing surfaces for the transmission of torque from one flange to the other. The engaged bearing surfaces of each clutch element lie in a plane which passes through the axis of rotation of the coupling. A bolt, which has oppositely pitched threads, is mounted for rotational movement by a guide on the coupling, and the axis of rotation of the bolt extends in a direction transverse to the axis of the coupling. A pair of tension shoes are carried on the bolt for displacement in opposite radial directions upon rotation of the bolt for preventing axial displacement of one coupling flange with respect to the other. Each clutch element has a further bearing face which bears against one of the tension shoes. The tension shoes are configured such that the distance between these bearing faces and the longitudinal axis of the bolt decreases in a direction extending radially away from the center of the coupling.

    The invention relates to the field of engineering.
    It is known quick-disconnect coupling flanges of couplings connected to each other by means of axial cams. Contains a 5 tightening unit made in the form of a bolt placed in guides perpendicular to the axis of the flanges of the bolt with two-sided screw thread of the opposite direction and tightening parts in contact with the cams | lj.
    A disadvantage of the known device is that during operation, the lingering parts are squeezed one from the other in the axial direction, as a result of which the reliability of the connection is reduced.
    In order to increase reliability, each flange is made with two cams, one of the contact surfaces of each cam lies in a plane passing through the axis of the flanges, and the other - in contact with the protracted part - is made inclined to the axis of the bolt with a slope directed from the bolt head. The long pieces in cross section are in the shape of a parallelogram or can be made in a pyramidal shape, and at least one of their surfaces is inclined to the joint axis at an angle less than 90 °. In addition, the protracted parts can be made conical in shape.
    In FIG. 1 shows a quick connection drive and driven units; in FIG. 2 is the same, section AA of FIG. 1; in FIG. 3 - connection with a protracted part, top view; in FIG. 4 lingering detail, side view; in FIG. 5 the same, top view; in FIG. G - connection with a modified protracted part, top view; in FIG. 7 - the lingering part of FIG. 6 is a side view; in FIG. 8 is a lingering part of FIG. 6, top view; in FIG. 9 - connection with a protracted detail of a conical shape, top view; in FIG. 1O “lingering part of conical shape, side view; in FIG. 11 is the same, top view.
    A quick-connect connection connects the coupling flanges, and the flange 1 is connected to the connecting blade 2. Valimo—
    715038 4 flange 3 acting with a flange 1 is connected to the articulated fork 4 of the universal joint. Each flange 1,3 is made with two cams 5 and 6. Both cams 5 and 6 of the corresponding flange 1,3 are engaged 5 with each other and thereby transmit torque from one half of the coupling to the other. This transmission is carried out from the cam 6 through its surface 7 to the surface 8 of the cam 5. The contact surfaces 7.8 pass in the same plane passing through the axis of rotation 9. Torque transmission can also occur in the reverse order. The supporting surfaces 10 of the cams 5 and 6 serve only to tighten both halves of the clutch relative to one another. Each bearing surface 10 of the cams 5,6 interacts with the drawn surface 11 of the drawn piece 12. These drawn surfaces 11 of the drawn piece 12 extend at a distance from the axis 13 of the bolt 14. The circumferential force is the resultant force that decomposes into a force perpendicular to the drawn surface 11 and on the force acting in the radial direction, 'which contributes to the protracted' Part 12 is squeezed out. To carry out the actual tightening of both halves of the coupling relative to each other, the tightening part 12 is located radially movably on the threaded bolt 14 and its movement is carried out by means of the head 15. The bolt 14 is installed in the guide part 16, When the head 15 is turned, the tightening parts 12 either move outward, or inside. To ensure easy assembly of both flanges of the coupling 1.3 during installation, the flange 1 is provided with a centering ring 17. The flange 1 with its cam 6 (see Fig. 3) is clamped by means of the supporting surface 10 with one tightening surface 11 of the tightening part 12. Another tightening surface 11 the tightening part 12 engages with the corresponding bearing surface 10 of the flange 3, due to which there is mutual pressing with mixing, i.e. puff
    After mounting both halves of the coupling by turning the bolt 14, the tightening parts move outward and fasten the connection. To connect with the bolt 14, a hole 18 is made in the tightening part 12. The connection shown in the League. 6 has a lingering part 12 ^ whose outer contour is square in plan. This embodiment contributes to the fact that the circumferential force acts on two drawn surfaces 11 located mirror-symmetrically but. The protruding surfaces 11 (see FIGS. 7 and 8) in the radial direction are made tapering. The external contour of such a part 12 is pyramidal. The lingering part 12 shown 15 (see Fig. 9) is made conical. This connection, as shown in FIG. 6 free of axial forces.

    37 acting with a flange 1 flange 3 sood foams with a hinged fork 4 universal joint. Each flange 1.3 is made with two cams 5 and 6. Both cams 5 and 6 of the corresponding flange 1.3 interlock with each other and transfer the torque from one coupling half to the other. This transmission is carried out from the cam 6 through its surface 7 to the surface 8 of the cam 5. The contact surfaces 7.8 pass in the same plane passing through the axis of rotation 9. Transmission of torque can also occur in reverse order. The bearing surfaces of the jaws 5 and b serve only to tighten both halves of the coupling one relative to the other. Each bearing surface 10 of the cams 5,6 interacts with the tightening surface 11 of the tightening part 12. These tightening surfaces 11 of the tightening part 12 extend from the axis 13 of the bolt 14. The circumferential force is the resultant force that perpendicular to the force exerted on the pulling surface 11 and the force acting in the radial direction, which causes the pressure on the element 12 to be squeezed out. To perform the actual tightening of both halves of the coupling with respect to each other, the tightening part 12 is located radially movable on the threaded bolt 14 and is moved by means of the head 15. The bolt 14 is installed in the guide part 16. When turning the head 15, the tightening parts 12 both move either outward or inward. To ensure easy mounting of both flanges of the coupling 1.3 during installation, the flange 1 is provided with a centering ring 17. The flange 1 with its cam 6 (see FIG. 3) is clamped by means of a supporting surface 1O with one tightening surface 11 of the pulling part 12. Another The tightening surface 11 of the tightening part 12 engages with the corresponding thrust surface 1O of the flange 3, due to which mutual pressing with displacement, i.e. zatka After the two halves of the coupling have been mounted, by turning the bolt 14, the tightening parts move outwards and seal the connection. A hole 18 is made to connect to the bolt 14 in the bolt 12. The connection shown in League. 6 has a tightening part 12 whose outer contour is square in plan. This embodiment contributes to the fact that the circumferential force acts on two tightening surfaces 11 arranged mirror-symmetrically. The pulling surfaces 11 (see Figs. 7 and 8) in the radial direction are tapered. The outer contour of such a part 12 is obtained pyramidal. The end piece 12 shown (see Fig. 9) is conical.
