Definitions

  • the present invention relates to a Bodenveiquessvortechnisch with vibration drive, wherein the vibration drive for generating a directional vibration movement has at least two arranged in opposite directions synchronously rotating unbalance exciter waves imbalances.
  • Such soil compaction devices consist in particular of road rollers; The same principle can also be applied to plate vibrators.
  • Known ground compaction devices have, for example, two imbalance exciter shafts arranged horizontally next to one another which, by changing their phase position, make it possible to generate different compaction and drive directions.
  • the two excitation shafts since they have different directions of rotation, they must be arranged at a sufficient distance from each other to prevent a collision of the imbalances. This leads to a correspondingly large space requirement.
  • soil compacting devices which have three unbalance exciter shafts, which are not arranged side by side, but in alignment one behind the other, wherein the two outer unbalance exciter shafts rotate in the same direction and they are interconnected by the middle unbalance exciter shaft, which is designed as a hollow shaft.
  • the average unbalance exciter shaft receives the required opposite direction of rotation, it must be reversed by a separate gear arrangement to one of the two be coupled outer unbalance exciter shafts. This also makes an adapted enlarged space required.
  • the present invention has for its object to improve the known soil compacting devices in terms of the arrangement of their unbalance exciter shafts so that they are characterized by optimized installation conditions.
  • This object is achieved in that the two imbalances are divided into two and their unbalance parts are assigned to each separate two mutually in the same direction exciter shafts such that the two imbalance parts of the first imbalance are arranged on axially aligned excitation shafts that provided the second imbalance between the two exciter shafts is, and that the two unbalance parts of the second imbalance on mutually parallel and offset from the exciter waves of the first unbalance extending exciter waves are arranged.
  • the ground compaction device allows a space optimization by coupling all four excitation shafts, that is to say even the oppositely circulating exciter shafts, to one another can be that can be dispensed with a separate gear to reverse the direction of rotation.
  • the exciter shaft of one of the two imbalance parts of the first imbalance is coupled directly to the exciter shaft at least one imbalance part of the second imbalance, that the excitation shafts of both imbalance parts of the second imbalance are coupled directly to the exciter shaft of an imbalance part of the first imbalance, and that the drive shaft of the vibration drive which drives an unbalance part of the first unbalance part of the first unbalance associated exciter shaft, this exciter shaft which drives the two unbalanced parts of the second unbalance associated exciter, and drives one of the two exciter waves of the second unbalance the other unbalance part of the first unbalance associated exciter shaft.
  • the exciter shaft of one of the two imbalance parts of the first imbalance is coupled directly to the exciter shaft at least one imbalance part of the second imbalance, that the excitation shafts of both imbalance parts of the second imbalance are coupled directly to the exciter shaft of an imbalance part of the first imbalance, and that the drive shaft of the vibration drive which drives an unbalance part of the first unbalance part of
  • the exciter waves of both unbalances are mounted in a common frame which is pivotable about an axis parallel to them and lockable in the desired pivot position, starting from a reference position with vertically superposed exciter waves of the second imbalance on both sides, in particular should be adjustable to about 90 °.
  • each unbalance exciter shaft 1 to 4 has an associated imbalance weight 11, 12, 13, 14, wherein the imbalance weights 11 and 14 of the unbalance exciter shafts 1 and 4 on the one hand and the imbalance weights 12 and 13 of the unbalance exciter shafts 2 and 3 on the other hand are arranged in each case in the same orientation to each other, in order then to allow addition to a first unbalance A or second unbalance B, both of which generate total imbalances of equal size centrifugal forces.
  • the unbalance exciter shaft 1 which rotates in the counterclockwise direction, has a gear 21 on the front side, which is in engagement with a gear 22 of the unbalance exciter shaft 2 and a gear 23 of the unbalance exciter 3 and both unbalance exciter shafts thereby in the opposite direction, ie clockwise drives.
  • the unbalance exciter shaft 3 has on the end face opposite the toothed wheel 23 a further toothed wheel 23a, which meshes with a toothed wheel 24 of the unbalance exciter shaft 4 and drives the exciter shaft 4 in turn in the opposite direction, ie in the same direction of rotation as the exciter shaft 1.
  • FIG 2 the reference position for the pivoting of the frame is shown, in which the frame is not pivoted relative to the roll drum and the two exciter shafts 2 and 3 of the second imbalance are arranged vertically one above the other.
  • a position of the frame 7 is shown in Figure 3, in which it is pivoted by 45 ° relative to the reference position.
  • FIGS. 2 and 3 each show two phases which illustrate the function of the imbalances, namely a first phase in which the centrifugal forces of the imbalances-in the horizontal direction in FIG. 2 and by 45 ° in the lower left in FIG the unbalances on the one hand and the arrows corresponding to the centrifugal forces on the other hand are shown by solid lines; in the second excitation phase, which is indicated by dashed lines, the centrifugal forces add up, so that a total centrifugal force F arises, which is directed vertically downwards in FIG. 2 and 45 ° downwards in FIG.
  • the present invention thus has the advantage that the total imbalance can be distributed to a total of four exciter waves, which on the one hand increase the limit speeds and on the other hand can increase the centrifugal force by using heavier imbalance weights.
  • the soil compacting device according to the invention is distinguished by optimized installation conditions of the associated exciter shafts.
