    The invention relates to earthmoving machinery, namely, devices for fastening the teeth of the working bodies of earthmoving machines.
    The purpose of the invention is to increase the service life of the tooth attachment unit.
    FIG. 1 shows a tooth attachment assembly, side view; Fig 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in Fig „4 - plug, cut; in fig. 5 - locking pin, side view; at aig. 6 - the same, front view; at aig. 7 is a sectional view in FIG. 5 in FIG. 8 is a section BB in FIG. five; on league. 9 - section GG on the League. five; in fig. 10 - holder, view from the right (non-locking) side; in fig. 11 - the same, view from the left (fitted with a constipation) side, and the plug in the removed position; on league. 12 - the end of the holder, front view; FIG. 13 is a section DD-D in FIG. 2
    The assembly 1 of the tooth of the working body of the earth-moving machine comprises a holder 2 for rigid fastening to the working body, for example, a bucket, located in the rear part of the tooth 3 with a front cutting edge 4, a mounting nest 5, a locking vertical pin 6 and a plug 7. The holder 2 is made with mounting a protrusion 8 at the front end having screw ridges 9 and clamps 10 on the outer surface. The mounting socket 5 of the tooth 3 has screw hollows (not shown) on the inner surface for interaction with the corresponding ridges 9 of the protrusion 8 and prisoners at its rear end portion of stacking tongues 11 which are located towards the base of the holder and formed with protrusions 12 at their ends directed towards the mounting projection 8 "Locking pin 6 is located outside of the mounting projection 8 and perpendicular to its

    the longitudinal axis and is installed with the possibility of jamming engagement with the protrusion 12 of the tongue 11 of the socket and with the clips 10 of the mounting protrusion 8. The clips 10 of the mounting protrusion are located on one side of the protrusion 8 relative to its middle vertical plane, placed with a gap between them and directed horizontally from the mounting the protrusion 8. The latter is made with a hole 13 located perpendicular to the longitudinal axis of the mounting protrusion and between its clamps 100. The locking pin 6 is made with a flat surface 14 facing the mounting at the protrusion 8, with a convex rear surface 15 for engagement with the protrusion 12 of the tongue 11 of the socket 5, with a concave front surface 16 for engagement with the clips 10 of the mounting protrusion 8 and with a notch 17 on the surface 18 facing the mounting protrusion "Lower end of the pin 6 is bevelled in the direction from the surface 18 with the recess 17 to its lower end surface 19. The plug 7 is installed in the hole 13 of the mounting protrusion 8 with the ability to interact with the notch 17 of the pin 6 and is made of a shank 20 with a helical spring 21 located around it and conical head 22 and of the elastic body 23 covering the turns of the helical spring 21.
    The assembly of the tooth attachment unit is carried out as follows.
    The tooth 3 is mounted on the holder 2 by linear movement along its central longitudinal axis and the rota of the tooth at an angle of approximately 45 ° until the helical crests 9 of the holder 2 enter into the corresponding depressions of the mounting slot 5. At the same time, the tongues 11 of the mounting slot 5 with notches 24 are placed on the last
    stages of rotation of the tooth in the mating notches 25 of the holder 2. Then the pin 6 is inserted into the recess 24 of the tongue 11 from the side of the holder clamps 10, and the pin 6 is deformed, as shown by the dotted line (Fig. 1 and 3), to provide the attractive tooth 3 effort. The creation of such an attractive force is facilitated by a width-varying profile of the pin 6, having a larger radius of curvature of the concave front surface 16 and a smaller radius of curvature of the convex rear surface 15 "When the locking pin 6 is installed, its front surface 16 contacts with a pair of vertically arranged clips 10 , and the back surface 15 is in contact with the protrusion 12 on one of the tongues 11 teeth
    During assembly time, the narrow end of the pin 6 with the bottom end surface 19 (Figs. 5, 6, and 9) enters without resistance into the existing hole between the protrusion 12 of the tooth tongue 11 and the protrusion 26 (FIG. 12) stretched between the vertically spaced clips 10 "When pin 6 is inserted into this hole, its rear surface 15 enters the hole
    The protrusion with the protrusion 12 of the tooth 3, so that a horizontal deLormation of the pin occurs, which creates a force that attracts the tooth relative to the protrusion 12 of the language 11. The geometries of the front 16 and rear 15 surfaces of the pin 6 are such that a wedging attracting effect on the protrusion 12 of the tooth . The deficiency of the straight conical wedge, which results in the occurrence of a component of the load on the tooth, which tends to displace the wedge, is eliminated. In the proposed construction, such a component is absent, the geometry of the pin ensures a stable jamming
    effort about
    When assembling, the bevelled end of the pin 6 interacts with the plug 7, the conical head 22 of which is placed in the recess 17 of the pin "Shank 20
    bakes its large deformation without losing its elasticity due to its protection against water foam.
    Incorrect installation of the pin 6 is prevented by making its lower end with the end surface 19 beveled. The beveled end of the pin 6 interacts with the conical head 22 of the plug 7 so that when the pin is inserted into the mount, the plug is guided under the action
    Because of the taper head 22 attached to the support part 27 by means of an intermediate cylindrical section 28, the jamming of the plug 7 does not occur when the pin is positioned in the opposite orientation. In this case, the bottom end surface 19 (FIG. 6) of the end of the pin 6 is in a plane contact with the cylindrical section 28 of the end of the plug so that assembly is impossible. Installing the pin in the inverted state is prevented in the same way. The tooth is removed from the holder in reverse order.
