Definitions

  • Such unbalanced vibrators designed as directional vibrators are used in particular in the case of self-moving vibratory plates in which the direction of movement of the vibratory plate can be changed by changing the direction of vibration.
  • two flyweights with imbalance shafts parallel to one another and mounted in a common housing rotate in opposite directions.
  • Each of the centrifugal weights generates a centrifugal force rotating with the drive speed. Due to the opposite rotation of the two centrifugal weights, the centrifugal force components cancel each other out in one plane, while they add up in the plane perpendicular to it. This creates a resulting vibration in one plane.
  • the position of this vibration level depends on the mutual phase relationship of the rotating centrifugal weights and can be changed by changing this phase relationship.
  • a known arrangement which allows a constant adjustment of the flyweights during the run, is that the unbalanced shafts are each provided with a gear.
  • the two gears are meshed with idler gears, the idler gears in turn meshing with each other.
  • the intermediate gears sit on rockers which are pivotable about the axes of the unbalanced shafts and are connected to one another by a link, so that they form a parallel link mechanism with this link.
  • One of the unbalanced shafts is driven.
  • the parallel link mechanism By swiveling the parallel link mechanism with the two rockers, the angular position of the other unbalanced shaft relative to the driven unbalanced shaft is changed and thus the position of the resulting vibration plane.
  • the invention is based on the object of relieving the displacement mechanism of such vibrations in an unbalance vibrator of the type defined at the outset.
  • Each of the rockers on the side opposite the idler gear with respect to the axis of the unbalanced shaft has a counterweight.
  • each of the rockers can be individually balanced, so that the resulting vibrations of the unbalance vibrator, even if they do not fall in the longitudinal direction of the rocker, do not exert any moments on the rocker about the axis of the unbalanced shaft.
  • Embodiments of the invention are the subject of the dependent claims.
  • the unbalanced mass vibration generator includes a Hous' se 10 in the housing 10, a first unbalanced shaft is mounted in bearings 14 12th
  • the first unbalanced shaft 12 carries a first flyweight 16. It is connected to a first gear 18.
  • a pulley 20 is seated on the first unbalanced shaft 12, via which the first unbalanced shaft 12 can be driven by a motor (not shown).
  • a second unbalanced shaft 22 is mounted in the housing 10 in parallel to the first unbalanced shaft 12 in bearings 24 and 26. It carries a second flyweight 28, which is formed here by two part weights 28A and 28B arranged symmetrically on both sides of the flyweight 16.
  • a second gear 30 is connected to the second unbalanced shaft 22. The two gears 18 and 30 are not in engagement with each other.
  • a first rocker 32 is pivotally mounted about the axis 33 of the first unbalanced shaft 12.
  • a second rocker 34 is pivotally mounted about the axis 36 of the second unbalanced shaft 22.
  • the rocker 34 consists of two halves 34A and 34B which are mounted on the second shaft 22 via ball bearings 38 and 40 on both sides of the gearwheel 30 and by a pin 42 at a distance from the second shaft 22 are connected.
  • the rocker arm 32 is mounted on the first shaft 12 in a similar manner.
  • a link 44 is articulated on the first and second rocker arms 32 and 34.
  • a bolt 46 extends between the two parts 34A and 34B of the rocker 34.
  • the link 44 is articulated between these parts 34A and 34B via a needle bearing 48 in one end.
  • the link 44 is articulated on the rocker 32.
  • the distance of the axis 50 about which the link 44 is pivotally articulated on the rocker 34 from the axis 36 of the second shaft 22 is the same as the distance of the axis 52 about which the link 44 is pivotally articulated on the first rocker 32, from the axis 33 of the first unbalanced shaft 12.
  • the effective length of the link 44 i. H. the distance between the axes 50 and 52 is equal to the distance between the axes 33 and 36 of the unbalanced shafts 12 and 22, respectively. It is thereby achieved that the axes 33, 36, 50 and 52 always form the corners of a parallelogram and the rockers 32 and 34 always run parallel to one another.
  • a first intermediate gear 54 is rotatably mounted on the first rocker 32 at a distance from the axis 33 of the first unbalanced shaft 12.
  • the first idler gear 54 is engaged with the first gear 18.
  • a second idler gear 56 is rotatably supported on the second rocker 34 at the same distance from the axis 36 of the second imbalance shaft 22 that the first idler gear 54 is from the axis 33 of the first imbalance shaft 12 has.
  • the second intermediate gear 56 is rotatably mounted on the pin 42 via a needle bearing 58.
  • the first intermediate gear 54 is mounted on the rocker 32 in the same way.
  • the second intermediate gear 54 is engaged with the second gear 30. 1, it is also in engagement with the first intermediate gear 54.
  • the second unbalanced shaft 22 is driven by the first unbalanced shaft 12 via the gear 18, the first intermediate gear 54, the second gear 56 and the second gear 30, in opposite directions to the unbalanced shaft 12.
  • the two rockers 32 and 34 can be pivoted by means of an adjusting mechanism 60, which will be described later.
  • each of the rockers 32 and 34 has a counterweight 62 and 64 on the side opposite the intermediate gear 54 and 56 with respect to the axis 33 and 36 of the unbalanced shaft 12 and 22, respectively. Due to the counterweights, each of the rockers 32 and 34 is' balanced with respect to its pivot axis, namely the axes 33 and 36, respectively.
  • the link 44 is articulated on the rocker arms 32 and 34 on the side opposite the intermediate gears 54 and 56 with respect to the axes 33 and 36 of the unbalanced shafts 12 and 22, respectively.
  • the adjustment mechanism 60 includes a toothed segment 66 that is attached to one of the rockers, in the preferred embodiment shown, to the second rocker 34.
  • the toothed segment 66 is curved about the axis 36 of the associated unbalanced shaft 22.
  • a toothed rack 68 is guided in longitudinally displaceable fashion in bushings 70, 72 and engages with the toothed segment 66.
  • the rack 68 is adjustable by means of movement transmission means, which in the preferred exemplary embodiment shown are formed by a Bowden cable 74.
  • a relatively light adjustment mechanism with a Bowden cable 74 can be used for the adjustment.
