    Roller cutters are mounted onto a cutterhead from the rear side of the cutterhead. A load transfer block is insertable between a stator portion of each cutter and a generally forwardly directed load-carrying surface on the cutter-head frame. Loads imposed on the roller cutter during boring are transmitted rearwardly from the stator to the load transfer block, and from the load transfer block to the cutterhead frame.

    The invention relates to devices for placing the cones into a chisel from the rear side, in particular to a device for installing the cones, which perceives the shock load on the cones during cutting and / or compression and directly transmits it to the chisel frame.
    The purpose of the invention is to accelerate the change of the cone.
    Figure 1 shows a roller cone of a drill bit, a general view; figure 2 is the same, the Assembly of the node from the back side of figure 3 is the same, view from the rear side; 4 is the same, axial section; figure 5 is the same, the diametric section.
    I The bit assembly of a drill bit comprises a housing 1 with a window 2 directed toward the bottom of the well, and with a hole 3 larger than the size of the roller cutter 4 directed to the rear. In case 1, at least one roller cutter 4 is installed on the rear side. Roller 4 has one cutting wheel 5 and two stators 6. Case 1 has a pocket 7 for roller cutter 4, built-in supports 8 placed around the perimeter of window 2 to limit the protrusion of the outside circle 5, guiding elements 9 for reciprocating movement of the roller cutter 4 and installing its stators 6 and at least one pair of stops 10 directed forward. The ball 4 is fixed in the housing 1 by means of a pair of blocks 11 for transferring the load from the cutting wheel 5 to the body 1 and bolts 12, which secure the blocks 11 to the body 1.
    The node works as follows.
    The roller 4 is inserted and removed from the pocket 7 of the housing 1 on the dark side through the opening 3. The housing 1 has built-in supports 8, times 4
    2 around the perimeter of the window to limit the protrusion of the outer part of the cutting wheel 5 of the roller cutter 4. The roller cutter 4 is inserted into the housing 1 along the guide elements 9, into which the stators 6 are tightly attached, to the stops 10. The roller cutter 4 is fixed using blocks 11 between the stators 6, the roller cutters 4 and the lugs 10, and the bolts 12, wherein the shock loads acting on the cutting Kpyf 5 are transmitted through the blocks 11 directly to those parts of the housing 1 where the lugs 10 are located without overloading the bolts 12.

    Invention Formula
    A drill bit assembly, comprising a housing with a window facing the bottom of the well, and with a hole larger than the cutting edge size, pointing to the back side, at least one rolling cutter installed on the back side of the housing and having one cutting wheel and two stators, while the housing has a pocket for the cutter and built-in supports placed around the perimeter of the window to limit the protrusion of the outer part of the cutting wheel, and means for attaching the small joint, which is tentatively due to the fact that guiding elements for reciprocating movement of the roller cutter and mounting its stators, at least one pair of stops directed forward, and the means of fastening the roller cutter each have a pair of load transfer units from the cutting circle to the body, mounted between the stators and the corresponding stops, and bolts, securing the blocks to the case.
