Definitions

  • the invention relates to a vibration exciter for a soil compacting device according to the preamble of claim 1.
  • Such vibration exciters are mainly used advantageously with vibration plates and are such.
  • B. is known from EP 0 358 744 B1.
  • a similar vibration exciter is described in DE 100 38 206 AI. It has two unbalanced shafts coupled in a form-locking, counter-rotating manner, each of which carries a fixed unbalanced mass and an unbalanced mass which is rotatable relative to the fixed unbalanced mass and thus rotatable with the unbalanced shaft.
  • the position of the moving unbalanced masses can be actively changed over a wide range by setting directions.
  • the interaction of the various unbalance masses results in a total force that can be directed in the forward or reverse direction of travel, depending on the operator's request.
  • the change in the direction of travel is brought about by the control devices that control the movable unbalanced masses. If the operator wishes the soil compactor to stop, the resulting force of the flyweights is set in the vertical direction. This also means that a targeted compaction of the soil can be achieved when the machine is stationary.
  • a vibration exciter is described in DE 199 43 391 AI, in which the phase position of the centrifugal weights can be set such that the vertical components of the centrifugal forces generated by the centrifugal weights cancel each other, while the horizontal components of the centrifugal forces add up in the same direction ,
  • This makes it possible for the vibration plate to no longer introduce vertical vibrations into the ground when standing, but rather to introduce shear stresses into the ground via a ground contact plate, with which e.g. B. cracks and pores can be compacted in an advantageous manner on an asphalt surface.
  • the invention is therefore based on the object of further developing a vibration exciter of the aforementioned type such that an excessively strong compaction of the soil in stationary operation due to strong vertical vibrations can be avoided without the operator or the soil to be compacted being exposed to strong horizontal vibrations in return.
  • a vibration exciter preferably has two unbalance shafts which are parallel to one another and can be driven in opposite directions at the same speed, each of which carries a fixed unbalanced mass and an unbalanced mass which is rotatable relative to the fixed unbalanced mass or the respective unbalanced mass.
  • Each of the unbalanced shafts is assigned an EmsteU device, with which the relative position of the respective movable unbalanced mass with respect to the unbalanced shaft carrying it can be adjusted.
  • the relative positions of the movable unbalance masses with respect to the Balancing shafts can be set in such a way by the control units that the centrifugal forces generated by the unbalanced masses when the unbalanced shafts rotate cancel each other out in every rotational position of the unbalanced shafts.
  • each unbalanced mass creates a centrifugal force; however, the centrifugal forces are adjusted in terms of direction and amount so that they compensate for the total.
  • the vibration exciter therefore does not generate any vibrations in this operating state (standing position), even though the unbalanced shafts rotate.
  • the relative position on each of the unbalanced shafts can be adjusted in such a way that the centrifugal forces of the unbalanced masses carried by this unbalanced shaft cancel each other out of the unbalanced shaft. This means that even with operation with only one unbalanced shaft, a relative position can be reached in which there is no vibration effect.
  • the relative positions can be changed in a preferred embodiment of the invention such that the centrifugal forces of the unbalanced masses do not cancel each other out, but rather that a resulting total centrifugal force has a horizontal component. This allows the vibratory plate to move, as is known from the prior art.
  • unbalance mass is meant abstractly in connection with this description. Of course, an unbalanced mass can also consist of several unbalanced elements which are distributed on the respective unbalanced shaft.
  • FIG. 1 shows a section in plan view through a vibration exciter according to the invention in the standing position
  • Fig. 2 schematic sections through two unbalanced shafts in different rotational positions with the respective positions of the unbalanced masses.
  • vibration exciters in various forms are known. Likewise - such. It is known, for example, from DE 199 43 391 AI - so-called “phase control devices", that is to say setting devices for adjusting relative positions between unbalanced masses and unbalanced shafts. Since the invention does not provide the detailed and specific design of a specific vibration exciter or a specific setting device, Rather, it concerns a relative position (phase position) that is particularly suitable for this but not yet known, a detailed description of the vibration exciter is not necessary.
  • Two unbalanced shafts 2, 3 are rotatably mounted in a housing 1, the unbalanced shaft 2 being driven in rotation by a drive (not shown).
  • the unbalance shaft 2 carries unbalance elements 4 and 5, which with the unbalance shaft 2 are firmly connected and form a fixed unbalanced mass.
  • a rotatably movable unbalanced mass 6 is arranged on the unbalanced shaft 2, which can be rotated relative to the unbalanced shaft 2 via a hub 7 and bearing 8.
  • the relative position between the movable unbalanced mass 6 and the unbalanced shaft 2 is determined with the aid of an control device 9.
  • the operating principle of such a EinsteU listening has long been known and z. B. described in DE 100 38 206 AI.
  • the adjusting device 9 essentially has a piston 10 which is axially adjustable under hydraulic action and can be moved axially back and forth in a hollow region of the unbalanced shaft 2.
  • the piston 10 carries a transverse pin 11 which penetrates two longitudinal grooves 12 formed in the wall of the unbalanced shaft 2 and engages in spiral grooves 13 which are formed on the inside of the hub 7.
  • the unbalanced shaft 2 also carries a gear 14 which meshes with a gear 15 which is attached to the unbalanced shaft 3. Via the gears 14 and 15, the rotational movement of the driven unbalanced shaft 2 is positively transmitted to the unbalanced shaft 3, which thus rotates in opposite directions but at the same speed.
  • the unbalanced shaft 3 carries two unbalanced elements 16, 17, which together form a fixed unbalanced mass. Furthermore, an unbalanced mass 18, which is rotatable on the unbalanced shaft 3, is provided, the relative position of which with respect to the unbalanced shaft 3 can be adjusted via an adjusting device 19. Since the control unit 19 has the same structure as the control unit 9, a detailed description is omitted.
  • the control of the unbalanced mass shown in the section of FIG. 1 corresponds to the relative control according to the invention, in which the individual forces generated by the respective unbalanced masses or elements cancel each other out (standing control).
  • the associated mr values (products from mass mx radius r of the unbalance center of gravity) must be coordinated accordingly.
  • the unbalance weights 2 and 3 can rotate without an out-of-balance effect and thus an oscillation occurring.
  • the movable unbalance masses 6, 18 are adjusted by the control devices 9, 19, however, this state of equilibrium is canceled, so that the desired vertical and horizontal vibrations for soil compaction can occur.
  • FIG. 2 shows highly schematic side views from the right in FIG. 1.
  • the hatched semicircles correspond to the movable, thus understandable, unbalanced masses 6, 18, while the non-hatched semicircles correspond to the unbalanced masses 4, 5 and 16, 17 which are fixed with respect to the unbalance weights 2, 3, as described for B. in the field a) "Stand" of Fig. 2 can be seen.
  • the movable unbalanced mass 6 has been rotated by 90 ° relative to the fixed unbalanced elements 4, 5 and the unbalanced weight 2.
  • the movable unbalanced mass 18 was rotated by 90 ° in the same direction as the movable unbalanced mass 6 with respect to the fixed unbalanced elements 16, 17 on the unbalanced weight 3.
  • the corresponding state is in Fig. 2a) shown in the column "Forward". Also here in the column 'Forward' under a) to d) different states of rotation of the unbalance weights 2, 3 are shown.
  • FIG. 2a A backward movement of the vibrating plate (to the right in Fig. 2) is shown in the right column of Fig. 2.
  • the moving unbalance masses 6 and 18 with respect to the unbalance weights 2, 3 carrying them have been rotated by 90 ° in the opposite direction to the forward direction and in relation to the stand control, as can be seen in FIG. 2a) in the "Backward" column.
  • the controls of the unbalanced masses shown in FIG. 2 are extreme controls. Depending on the extent to which the control devices 9, 19 are used, other intermediate positions, i. H. Control angle other than 90 ° can be reached, so that a continuous change between forward travel, stationary operation and reverse travel can be achieved.
  • control devices 9, 19 it is possible, on the one hand, to use known means such as hydraulic control, electric motors, electromechanical control devices, etc.
  • the moving unbalanced masses can also be controlled with the aid of simple push-pull cables which can be controlled by the operator via a common transmitter. This can save considerable costs even with simpler vibratory plates.
  • the control of the relative controls by the control devices 9, 19 should be able to be carried out synchronously. In some cases, however, it may also be expedient to enable the movable unbalanced masses to be individually controlled without the need for synchronization.

Abstract

Un oscillateur destiné à des engins de compactage du sol, par exemple, une plaque vibrante, présente des arbres de balourd (2, 3) parallèles ou coaxiaux, tournant en sens inverse à la même vitesse de rotation et portant respectivement un balourd (4, 5, 16, 17) fixe et un balourd mobile rotatif (6, 18) par rapport à l'arbre de balourd (2, 3). La position relative d'un balourd mobile (6, 16) par rapport à son arbre (2, 3) se règle par un dispositif de réglage (9, 19) de telle manière que les forces centrifuges produites par les balourds lors de la rotation de leurs arbres (2, 3) s'annulent dans leur totalité dans chaque position de rotation des arbres de balourd (2, 3). Cela permet notamment qu'une modification de la position relative soit effectuée de telle manière que la grandeur d'une force centrifuge totale résultant des balourds soit proportionnelle à une vitesse de d'avancement de l'engin de compactage du sol.
