Definitions

  • the invention relates to a torque support for two oppositely driven rollers with the characteristics of The preamble of claim 1.
  • the torque support serves the reaction moments of the two slip gear on the torque arms and the Short coupling rods in themselves. In this way if the drive torque is the same, none additional forces from the torque on the gearbox mounting as well as the roller bearings. With different Torques for the rollers only occur in the Magnitude of the difference in drive torque for the Bearings on.
  • Torque supports for two counter-rotating rollers known in which the torque arms in via coupling rods Articulation points with a traverse or with two torsion shafts are connected. Due to the continuous traverse and both torsion waves aligned with each other are all Articulation points on one side by the axes of the rollers arranged median plane. In operation, too this torque supports the one coupling rods under tension and the others under pressure.
  • the invention has for its object the generic To design torque support so that it is strong is claimed cheaper.
  • Two horizontally arranged rollers 1, 2 are part of one Roller mill for crushing regrind.
  • the rollers 1, 2 are spaced from each other so that a between them Roll gap is formed in which the material to be shredded is abandoned above.
  • To change the width of the Roll gap and to compensate for the wear of the Roll surface is one of the roller 1 fixed and the other roller 2 is not slidable in relation to the fixed roller 1 machine frame shown stored.
  • the directions of rotation of the Rollers 1, 2 are, as in the drawing by arrows 3, 4 is indicated, set so that one after in the roll gap downward feed direction is formed.
  • the two rollers 1, 2 each carry on the same roller side a roll neck 5, 6, on which a gear 7, 8 is attached is.
  • the gears 7, 8 are preferably as Planetary hollow shaft gear designed.
  • each transmission 7, 8 With the housing of each transmission 7, 8 are fixed two Torque supports 9 - 12 connected, which are the same in pairs.
  • a short torque arm 9, 10 is on the outside of the Gear 7, 8 attached while the other, longer Torque support 11, 12 the other roller 1, 2 as far engages that it is above the short torque arm 9, 10 is located.
  • the short torque arm 9, 10 of one Gear 7, 8 is with the longer torque arm 11, 12 of the other gear 7, 8 articulated via one in the articulation points 13 - 16 engaging coupling rod 17, 18 connected.
  • the Coupling rods 17, 18 are designed as double levers. Thinks one plane through the longitudinal axes of the rollers 1, 2 placed, so all articulation points 13 - 16 on one and are located on the same side of this central plane 19.
  • the torque support can also be used for oppositely driven Rollers 1, 2 are used which are not arranged horizontally. are. In these cases too, coupling rods 17, 18 occur only pulling forces on.

Claims (3)

  1. Support de couple pour deux cylindres (1, 2) entraínés en sens contraire, dans lequel un des cylindres est monté fixe et l'autre monté de manière à se déplacer par rapport au cylindre monté fixe, dans un bâti de machine, les cylindres (1, 2) sont munis sur la même face, dans chaque cas d'un tourillon (5, 6) sur lequel est monté un mécanisme (7, 8), des supports de couple (9 - 12) sont solidarisés avec les mécanismes (7, 8) et sont interconnectés de manière articulée, dans chaque cas en deux points d'articulation (13 - 16) par des tiges d'accouplement (17, 18), support de couple caractérisé par le fait que le support de couple (9-12) associé à un des cylindres (1, 2) chevauche dans chaque cas l'autre cylindre jusqu'à ce qu'il se trouve au-dessus du support de couple (9 - 12) associé à cet autre cylindre (1, 2), de sorte que tous les points d'articulation (13 - 16) des tiges d'accouplement (17, 18) sont disposés sur un côté d'un plan médian (19) traversant les axes des cylindres (1, 2).
  2. Support de couple selon la revendication 1, caractérisé par le fait qu'un point d'articulation (13, 14) associé dans chaque cas à une tige d'accouplement (17, 18) se situe dans la zone du plan médian (19).
  3. Support de couple selon les revendications 1 et 2, caractérisé par le fait que lorsque les cylindres (1, 2) sont disposés horizontalement, leurs sens de rotation sont orientés de manière à former, entre les cylindres (1, 2), une fente avec un sens d'alimentation dirigé vers le bas et de sorte que les points d'articulation (13 -16) se trouvent au-dessus du plan médian (19).
