Definitions

  • the invention relates to a device for holding two or more diametrically opposite each other on a drivable polygonal shaft in the Longitudinal offset staggered cutter knives, which by means of Receiving disks are held, the non-rotatably connected Receiving disks on the facing end faces each an open
  • Receiving disks which by means of Receiving disks are held, the non-rotatably connected Receiving disks on the facing end faces each an open
  • Have exemptions that differ from the height of the longitudinal axis of the polygonal shaft extend radially outward and are mirror images of each other, and the receiving discs radially and with respect to the longitudinal axis of the polygonal shaft perpendicular to a half-open in the cutter knives Recess alternately arranged outwards on the polygonal shaft are.
  • the object of the invention is therefore the holding device of the aforementioned To improve the genus in such a way that not only the installation and removal of the cutter knife is made easier and can be carried out in a short time, but above all that Knocking out the recesses machined into the receiving disks at the Assembly and disassembly on the knife shaft is reliably avoided.
  • the Cutter knives should therefore be able to be used over a long period of time, without having to accept an out-of-round run and this due to vibrations to be damaged.
  • the construction effort, by means of which this can be accomplished, should should be kept low, changing the cutter knife should also be made easier.
  • this is the case with a holding device of the type mentioned Art achieved in that two receiving disks and the one between them used cutter knife on a hexagon socket Intermediate member are arranged by means of evenly distributed over the circumference Spring catch is supported on the polygonal shaft.
  • the outer surface of the intermediate member is offset form in such a way that the one of the receiving discs via a press fit firmly connected to the intermediate link and the other receiving disc on the Intermediate member is slidably mounted.
  • the intermediate member connect, for example glue or shrink on this, and the to arrange other receiving disc slidably on the intermediate member.
  • the spring catches in the center of each straight line extending webs, preferably in each of the webs of the intermediate member, to arrange and through an inserted in a hole and over the Inner circumferential surface of the webs of the intermediate member and a projecting ball to form this acting spring supported on the intermediate member, the Provide holes with a conical bearing surface for the balls should be. As springs acting on the balls can enter the holes Pressed rubber or compression springs are provided.
  • Another advantage is that also between the polygonal shaft and the Intermediate radial play can be provided, through which the input and Removal of the pontic is facilitated, however, is a central recording of the pontic guaranteed.
  • This is namely are automatically centered, unbalances and vibrations caused by them therefore almost impossible.
  • the lifespan of the cutter knife is determined by the proposed intermediate link accordingly in a significant Dimensions extended, and the operating behavior of a cutter knife set is at only low construction costs significantly improved.
  • the device shown in Figure 1 and designated 1 is used for crushing of meat products in a cutter bowl, not shown, and consists in essentially from a driven polygonal shaft 2 rotatably clamped pairs of knives 11, 11 'and 11' ', each offset by 60 °.
  • This is the Polygonal shaft 2 with a contact collar 4, which has a stop surface 5 for the Knife pair 11 '' forms, and provided a threaded shoulder 3, on which a nut 6 is screwed on, which acts on the pair of knives 11 via a disk 7.
  • the contact discs 17 and 18 for receiving a as Hexagon socket 42 formed intermediate member 41 with recesses 19 and 20 provided, which are adapted to the profile of the hexagon socket 42.
  • the Receiving disks 17 and 18 are accordingly non-rotatably on the intermediate member 41 held.
  • the receiving discs 17 and 18 are opposite to the longitudinal axis A Polygonal shaft 2 arranged radially outwards, namely perpendicular to the axis semi-circular recesses 14 machined into the cutter knives 12 and 13 and 15 which receive the intermediate member 41.
  • the exemptions 21 and 22 each opposite part 17 '' and 18 '' of the contact discs 17 and 18 thus radially over their stepped part 17 'and 18', so that flywheels are formed, by which the rotational behavior of the knife pairs 11, 11 'and 11' 'favorable being affected.
  • the centers of the receiving discs 17 and 18 are with Marked M1 and M2, the large radial offset of the receiving discs 17th and 18 with respect to the longitudinal axis A of the polygonal polygonal shaft 2 thereby clearly recognizable.
  • Retaining bolts 25 are graded, as can be seen in particular in FIG. 1 formed and bores 26 machined into the receiving disks 17 and 18 and 27 used.
  • the in the offset part 17 'and 18' of the holding washers 17th and 18 incorporated bores 27 are in this case corresponding to the assigned Design of the retaining bolts 25, one in each of the cutter knives 12 and 13 reach through the trained bore 16, formed and adapted to this.
  • the identically designed retaining bolts 25 are arranged in mirror image to one another, the pairs of knives 11, 11 'and 11' 'are secure with the holding disks 17 and 18 connected.
  • the recesses 19 and 20 machined into the receiving disks 17 and 18 form stops 23 and 24 for at the longitudinal axis A of the polygonal shaft 2 the cutter knives 12 and 13, so that these, although in these the semicircular Recesses 14 and 15 are provided for receiving the intermediate member 41, are alternately rotatably supported on the receiving disks 17 and 18.
  • the stops 23 and 24 are the receiving disks 17 and 18 mutually locked.
  • the division into the receiving disks 17 and 18 incorporated holes 26 and 27 on the profile of the polygonal shaft 2 and the Supported intermediate member 41, the knife pairs 11, 11 'and 11' 'can thus in Longitudinal direction of the polygonal shaft 2 arranged slightly offset from each other become.
  • the webs 43 are further provided with spring catches 51 which extend into the webs 43 machined holes 46 inserted balls 52 and springs 53 exist.
  • the Balls 52 are on the rubber springs which are pressed into the bores 46 trained springs 53 are supported and are on the opposite side through a conical contact surface 47 provided in the end region of the bores 46 held.
  • the balls 52 protrude over the inner lateral surface 48 of the webs 43 addition, the intermediate member 41 is thus uniform over the circumference distributed spring catches 51 supported on the polygonal shaft 2.
