Definitions

  • the invention relates to a torque support for two oppositely driven rollers with the features of the preamble of claim 1.
  • the torque support is used to short-circuit the reaction moments of the two slip-on gears via the torque supports and the coupling rods. In this way, as long as the drive torques are the same, no additional forces from the torque occur on the gearbox bearing and the roller bearing. With different torques for the rollers, forces only occur in the order of magnitude of the difference in the drive torques for the bearings.
  • the torque supports and the coupling rods are of the same design.
  • the coupling rods connect the torque arms directly.
  • the articulation points of one of the coupling rods with the torque supports are located on one side of the connecting line of the pivot points of the rollers and the articulation points of the other coupling rod on the other side of the connecting line.
  • This torque support is designed simply, causes no or only minimal additional forces and requires little space.
  • one of the coupling rods is subjected to tension under load, while the other coupling rod is subjected to pressure due to the structural design.
  • a component that is subjected to tension must be clearly dimensioned, while in the case of a component that is subjected to pressure, a possible buckling must also be taken into account.
  • the invention has for its object to design the generic torque support such that it is claimed in terms of strength cheaper.
  • both coupling rods are subjected to tensile stress in the desired manner and are therefore clearly dimensioned.
  • the space on the side of the transmission facing away from the support can advantageously be used for the necessary accommodation of additional devices, or the entire system can be made smaller.
  • the requirement can be met to keep the distance between the rollers as small as possible and to a limited extent to adjust variably on both sides.
  • the drawing shows the side view on two rollers with a torque support.
  • Two horizontally arranged rollers 1, 2 are part of a roller mill for comminuting regrind.
  • the rollers 1, 2 are arranged at a distance from one another, so that a roller gap is formed between them, into which the material to be shredded is fed from above.
  • one of the rolls 1 is fixed and the other roll 2 is slidably mounted in a machine frame, not shown, relative to the fixed roll 1.
  • the directions of rotation of the rollers 1, 2 are, as in the drawing by arrows 3, 4 is indicated, set so that a downward feed direction is formed in the roll gap.
  • the two rollers 1, 2 each carry a roller journal 5, 6, on which a gear 7, 8 is attached.
  • the gears 7, 8 are preferably designed as planetary hollow shaft gears.
  • a short torque arm 9, 10 is attached to the outside of the transmission 7, 8, while the other, longer torque arm 11, 12 overlaps the other roller 1, 2 so far that it is located above the short torque arm 9, 10.
  • the short torque arm 9, 10 of the one gear 7, 8 is connected in an articulated manner to the longer torque arm 11, 12 of the other gear 7, 8 via a coupling rod 17, 18 engaging in the articulation points 13-16.
  • the coupling rods 17, 18 are designed as double levers. If one imagines a plane through the longitudinal axes of the rollers 1, 2, then all the articulation points 13-16 should be on one and the same side of this central plane 19.
  • the articulation points 13, 14 can be arranged in the short torque supports 9, 10 in the region of the central plane 19.
  • the torque arms 9-12 are aligned together with the coupling rods 17, 18 on one and the same side of the gear 7, 8. If the rollers 1, 2 are arranged horizontally, the articulation points 13, 14 should lie in the region of the central plane 19 and the articulation points 15, 16 above the central plane 19.
  • the torque support can also be used for rollers 1, 2 driven in opposite directions, which are not arranged horizontally. In these cases, too, only tensile forces occur in the coupling rods 17, 18.
