Definitions

  • the invention relates to a shaft and a device with at least one shaft with one tool shank and one arranged along its circumference Work area tools for crushing waste, in particular for crushing bulky waste.
  • Known shafts of the type mentioned are for fastening tools with axially spaced, circumferential fastening rings Mistake.
  • the fastening rings are welded onto the outer surface of the shaft and extend radially outward from there.
  • the tools are either direct welded or screwed to the mounting rings.
  • screwed on Tools have the mounting rings through holes in the axial direction on.
  • the tool shank of corresponding tools has a ring segment with a contour and threaded holes corresponding to the mounting ring Mount on the mounting rings using screws.
  • the work area Assembled tools protrude in the radial direction over the outer circumference of the Fastening ring.
  • Known devices of the type mentioned have at least one such a shaft, which is rotatable about its longitudinal axis in a machine frame stored and driven by a motor.
  • Comb through the tools during the rotation of the shaft for example, one or more combs attached to are attached to the machine frame of the device, or staggered Tools of a second shaft arranged in parallel.
  • the on crushing the forces acting on the tools are primarily tangential in the circumferential direction and directed against the direction of rotation of the shaft.
  • These powers are from that Working area of the tools over the tool shank and the screws on the Transfer the mounting rings of the shaft. The screws are in the shear direction loaded.
  • the height of the working area of the tools over the outer circumference of the Fastening ring is usually larger than the height of the fastening ring and thus the contact surface between the tool shank and the fastening ring.
  • the moments of force resulting from the forces that occur and the unfavorable leverage ratio result, act on the shear forces acting on the screws, reinforcing.
  • the unfavorable leverage ratio is compensated that the ring segment of the tool shank spans a large angle, so that the interface between the tool shank and the mounting ring and thus the static friction between the tool and the fastening ring itself enlarged accordingly. Nevertheless, screws are used to fix the tools with a very large cross section required.
  • the object of the present invention is therefore a shaft and a device to create that withstand a higher load without significant additional effort.
  • the object is achieved by a shaft and a device of the solved type mentioned, in which the tools arranged in pairs are that from each pair of tools one tool from one side and the other tool from the other side with its tool shank in one, assigned to the pair of tools, radially through the Shaft-extending through hole is inserted and that the work areas protrude radially beyond the outer surface of the shaft.
  • the advantage of the invention is that the working areas of the tools acting forces by means of the tool shafts extending into the shaft be derived on the wave.
  • the tools are always anchored regardless of the direction of loading equal.
  • the tools are preferably arranged in pairs since they are therefore per pair of tools only one through opening through the shaft is required and the cross section the shaft compared to individually arranged tools with the same number less weakened by tools.
  • the working areas are preferably radially opposite one another with respect to the shaft arranged.
  • the Tool shanks are at least partially tapered in the direction of their free end, so that the tool shanks of tools arranged in pairs against each other are wedged.
  • the tool shanks have a length that is larger than the diameter of the shaft, so that the free end of the tool shanks inserted tools from the through opening or tool holder protrudes, and if the tools in the area of entry and exit the tool shanks in or out of the through opening or tool holder are welded to the shaft or to the tool holder.
  • the tool shafts which are partially tapered in the direction of their free end on the one hand that the tools easier in the through openings or tool holder insert the shaft and thus assemble it. They effect furthermore, that the tool shanks jam during installation, so that the Tools in a positive connection with the shaft or the tool holder stand.
  • the tools then only need to selectively with the shaft or the tool holder to be welded so that they do not become Loosen operational. In any case, the welding spots do not have to be designed in this way be that they are sufficient to transmit power from the tools to the shaft.
  • a shaft 8 1 of a shaft 8 according to the invention from a hollow shaft 10, which of a radial in the central direction Hole is penetrated into which a tool holder 12 is inserted.
  • a solid shaft can also be used, for example.
  • the tool holder 12 is annular through two of the central bore circumferential welds 11 firmly connected to the hollow shaft 10.
  • the tools 9 have working areas 14 provided with superficial armor 15, which protrude beyond the lateral surface 17 of the shaft 10.
  • the tool shanks 16 Both tools 9 are so long that, in addition, each in the inserted state also the free end 18 on the side opposite the work area 14 of the tool protrudes from the tool holder 12.
  • Both the free end 18 of the tool shank inserted from the opposite side as well as the end of this side that is directly adjacent to the work area inserted tool shank is by means of a weld 20 on the tool holder 12 fixed.
  • the weld can be done selectively along the insertion opening in the tool holder or continuously hem the insertion opening.
  • the welds can can be removed by grinding for the purpose of dismantling the tools.
  • the tool shanks 16 are each tapered in the direction of their free end 18, so that the tools 9 when inserted in the tool holder 12 also clamp.
  • the plane of contact of the tool shanks 16 of tools inserted in pairs 9 is oriented perpendicular to the plane of rotation and representation.
  • the tool shanks by a located in the middle Franking 23 divided into two contact surfaces 21, 22.
  • the Wave i.e. when rotating in the direction of arrow 24, act upon loading the force application surface of the working area 14 against the direction of rotation 24 directed forces.
  • Due to the franking 23 is uneven or not completely parallel contact surface ensures that the lever that pulls the one out of the Force transmits resulting torque, not around a random point of contact along the common touch plane, but around the work area 14 distant point in the area of the contact surface 22 rotates. Because in the embodiment 1, the force application surface of the work area 14 on the the contact surface 26 of the tool shank 16 with the tool holder 12 is arranged away from the tool shank 16, the force in Essentially directly from the tool shank 16 to the tool holder 12 transferred.
  • the tool holder 12 is in FIG. 2 together with two inserted tools 9 and in FIG. 3 in perspective without tools.
  • she has a round cross-section, so that it is in a through hole designed as a bore can be used in the hollow shaft 10.
  • It is essentially composed of four elements: two in the axial direction at the ends of the Tool holder 12 located inlets 32, 34, each with a central, rectangular insertion opening 30 and two guide strips 36, 38, the extend in the axial direction.
  • the tools 9 are inserted, they slide Tool shafts 16 along the contact surface 26 on the guide strips 36, 38 into the tool holder until the cross section of the two tool shanks 9 corresponds to the distance between the two guide strips 36, 38.
  • One out Tool holder 12 composed of several elements, as in FIGS. 2 and Fig. 3 has compared to a solid, one-piece tool holder the advantage of a weight saving without, however, a substantial reduction in Having to put up with stability.
  • the tools 40 shown in FIG. 4 have a working area 42 with a fin-shaped hook profile curved in the normal direction of rotation 24 of the shaft.
  • the advantage of such a tool is that the working areas the tools in the opposite direction of rotation (in reverse operation) to the Combing the device clean itself, for example, around the tool 40 wire wound around it is stripped off.
  • the tools are also by means of a Insertion opening in the tool holder 12 completely surrounding seam 44 fixed to the tool holder 12.
  • Figures 6 to 9 show different alternative securing options that involve moving the tools prevent during use.
  • tools 50, 52 are by means of a tension screw 54 acting in the direction of insertion of the tools towards one another emotional.
  • the tools wedge due to the beveled sections 56, 58 of their contact surfaces and clamp inside the tool holder 12 firm.
  • a locking of the tools 60 is proposed, in which the tools 60 by means of a stud screw oriented at right angles to the direction of insertion 62 are held in their target position.
  • the stud screw 62 has in the connection a threaded section on a screw head 64 countersunk in the hollow shaft 72 66 and at the screw head distal end a cylindrical section 68 on which a through hole in the tool holder 70 and in enforced the tools 60.
  • a stud screw this can be used
  • any other oriented perpendicular to the direction of insertion and the Tool shafts locking locking element, such as a self-locking Bolt or cotter pin can be used.
  • the tools 80, 82 are separate wedge 84 clamped in the tool holder 12.
  • the tools each have a projection 86, 88 on the free of their tool shanks, the wedged state of the tools 80, 82 over the edge of the insertion opening protrudes and thus a displacement of the tools along the tool holder prevented.
  • the tool shanks 90, 91 of the tools according to FIG. 9 are in the region of the Franking 92 secured by a self-locking latch lock.
  • the self-locking Pawl lock consists of an oriented along the contact plane Teeth 94 in the tool shank 91 and a spring-loaded pawl 96, which is mounted in the other tool shank 90 and by its spring force pressed into the toothing 94 of the opposite tool shank 91 intervenes.
