Definitions

  • the invention relates to a vibration exciter (or a device for vibration excitation) for a soil compaction device.
  • the invention further relates to a soil compacting device with at least one such vibration exciter.
  • a generic vibration exciter and a Bodenverdichtungs réelle equipped hereby are for example from the US Pat. No. 7,059,802 B1 known.
  • the compaction rollers are subjected to vibrations in the compression mode.
  • the vibration is generated by one (or by several) vibration exciter.
  • a vibration exciter comprises an exciting shaft driven in rotation about a rotation axis, on which a so-called exciter weight (exciter mass) is arranged eccentrically.
  • exciter weight also means the structural totality of exciter weight and exciter wave, unless stated otherwise. Due to the eccentricity caused by unbalance usable vibrations are generated for the compression.
  • the envelope weight On the exciter shaft further at least one so-called envelope weight is arranged, which is also formed eccentrically (ie, the center of gravity is outside the axis of rotation).
  • the envelope weight is rotatably decoupled relative to the exciter shaft and the exciter weight arranged thereon or rotatable about an axis of rotation and can assume different angular positions in one, for example by stops, limited rotational range relative to the exciter weight.
  • the axis of rotation of the exciter shaft with the exciter weight and the axis of rotation of the envelope weight relative to the exciter weight are coaxial with each other.
  • the envelope weights are repetitively carried along by the rotating exciter shaft by means of a pin (or the like) from a lower position to a kinematic envelope point at which the envelope weights gravitationally tip over and from the opposite side to a stop provided therefor of the Apply the exciter shaft or the exciter weight.
  • the envelope weight may thus occupy a position depending on the direction of rotation of the exciter shaft in which the mass of the envelope weight in the rotational movement added to the exciter weight, whereby the oscillation amplitude is increased, and another position in which the mass of the envelope weight of the mass counteracts the exciter weight , whereby the oscillation amplitude is reduced.
  • the arrangement of exciter weight and envelope weight in the vibration exciter thus makes it possible to better regulate the vibration intensity of the vibration exciter.
  • a disadvantage of the vibration exciters known from the prior art is in particular the uncontrolled rebounding of the envelope weights when striking. Another and often associated disadvantage is that often no unambiguous handling of the handling weight takes place.
  • the envelope weight can take an indifferent position in the known arrangements. As a result, for example, the position in which the envelope weight is added to the exciter weight can not be reliably guaranteed or the maximum amplitude of the exciter unit can not be achieved. As a result, the maximum compaction power of the compacting machine can not be provided.
  • the CH 537 217 A discloses a device for varying the Studttel within a Haittelwelle, which is provided with two axially staggered centrifugal weights, one of which is fixedly connected to the Studttelwelle.
  • the DE 27 55 075 A1 describes an unbalance exciter with a first and a second unbalance body.
  • the first imbalance body has a hole eccentrically offset by a dimension "e" whose longitudinal axis is aligned parallel to the longitudinal axis of the imbalance body and which serves to receive a drive shaft therein.
  • the object of the invention is to develop a vibration exciter of the type in question such that the disadvantages associated with the prior art are avoided or at least significantly reduced.
  • the envelope weight relative to the exciter weight according to the invention does not pivot concentrically to the axis of rotation of the exciter shaft.
  • the envelope weight is rather pivotable on a relative to the axis of rotation of the exciter shaft eccentric rotation path relative to the exciter weight.
  • the arrangement according to the invention also facilitates the switching over of the direction of rotation of the oscillation arrangement.
  • the two axes of rotation may indeed lie in relation to one another in such a way that they intersect at one point or are skewed relative to one another.
  • the axes of rotation of the exciter shaft and of the at least one turnup weight are oriented parallel to one another. With this arrangement of the two axes of rotation each other optimum results can be obtained.
  • this embodiment is characterized by a comparatively simple mountability.
  • the axial offset of the two axes of rotation to each other is also ideally chosen in such a way that its position-stabilizing effect on the positioning of the envelope weight against the exciter weight on the two outer adjustment positions almost equally strong.
  • the axis of rotation of the at least one envelope weight is offset by a defined value with respect to the axis of rotation of the exciter shaft or of the exciter weight, wherein this value is dimensioned as an inwardly pointing distance on the bisector of the envelope angle.
  • the axial offset can basically be varied over a wide range. However, the positive effect of the invention already occurs at a relatively small axial offset.
  • a comparatively small axial offset also has the advantage that the vibration generator according to the invention can still be kept compact in its construction. Excellent results are thus achieved when the distance of the axes of rotation on the bisecting line in the range of 1 to 15 Millimeters, and preferably in the range of 1.5 to 10 millimeters, especially 2 to 5 millimeters.
  • the distance is measured in the plane which is cut perpendicularly at least from the axis of rotation of the exciter shaft.
  • the vibration exciter has exactly one excitation weight.
  • This excitation weight is preferably formed integrally with the exciter shaft.
  • the assembly and maintenance of the entirety of the exciter shaft and exciter weight or the vibration exciter is considerably simplified.
  • the number of turnover weights per exciter wave can also vary. According to the invention it is preferred if the vibration exciter has exactly one envelope weight. Particularly preferably, it is further provided that the vibration generator has only one envelope weight and only one exciter weight.
  • the axial offset of the two axes of rotation can be achieved in different ways.
  • One possibility for example, is to provide a bearing ring on the exciter shaft, which has an eccentrically arranged with respect to the axis of rotation of the exciter shaft inner jacket, on which finally the envelope weight is performed.
  • a corresponding journal is guided at the envelope weight in or through the bearing ring on the exciter shaft.
  • This bearing ring may be rotatably connected to the exciter shaft or, preferably, be integrally formed with the exciter shaft. If the bearing ring is an independent component, the variant according to the invention can, for example, also be retrofitted comparatively easily in a conventional exciter with coaxial axes of rotation. Overall, a hub connection or a hub bearing is thus obtained in this way.
  • a hub connection comprising a bearing hub or bearing pin and a bearing eye, provided for storage of the envelope weight on the exciter weight be.
  • the journal at the envelope weight is absorbed in this embodiment in an eye in the exciter weight.
  • the eye is in the form of a hole.
  • This embodiment is also particularly easy to install, since the envelope weight can be pushed directly onto the exciter weight and is then stabilized by the exciter weight itself in its position along the axis of rotation or in the axial direction at least in one direction.
  • the envelope weight has, at least at one axial end, a bearing ring which is particularly preferably formed integrally with the envelope weight and into which a corresponding journal on the structural unit of exciter weight and exciter shaft is guided or passed.
  • the envelope weight is not stored alone on a bearing on the structural unit of exciter and exciter shaft, but over several camps, especially two.
  • the two bearings can be constructed to the same, so that, for example, two coaxial with each other and in the axial direction one behind the other pins on Umtschmati are present, each engaging in a corresponding recess on the structural unit of exciter shaft and exciter weight.
  • differently constructed bearings can be combined with each other in a vibration exciter according to the invention.
  • the envelope weight in the axial direction of the parallel axes of rotation coming from the engine initially engages around a bearing ring on the exciter shaft with eccentric outer shaft to the axis of rotation of the exciter shaft and behind in the axial direction with a pin whose axis is coaxial with the longitudinal axis of the bearing ring, in engages a hole in the structural unit of exciter shaft and exciter weight.
  • This special arrangement prevents particularly easy axial displacement of the envelope weight against the assembly of exciter shaft and exciter weight and can be mounted quickly and easily by pushing the envelope weight on this unit at the same time.
  • the bearing ring of the envelope weight is arranged in the axial direction of the axis of rotation of the exciter shaft directly between a drive-side bearing and a stop on the exciter weight or on the exciter shaft. In the axial direction, the envelope weight is thus fixed in position between the stop and the drive-side bearing.
  • This embodiment is advantageous in that additional fixing means for axially securing the envelope weight are not required.
  • the exciter shaft is further preferred not to form the exciter shaft continuously, but Hergliedrig.
  • this is thus interrupted at least once between its two outer ends lying in the axial direction, so that a release is obtained between the individual members.
  • the individual members of the exciter shaft are connected to one another via the excitation weight, which may also be multi-membered, if necessary.
  • This release also serves in particular to simplify the assembly, since thereby postponing the envelope weight on the structural unit of exciter weight and handling weight is simplified. In addition, this arrangement allows a particularly favorable weight distribution.
  • the turn-over angle for the handling weight is in the range of 120 ° to 200 °, and is preferably approximately 130 °.
  • the envelope angle is determined in the plane perpendicular to the axis of rotation of the envelope weight with respect to the exciter shaft or relative to the exciter weight and is determined by the two maximum pivot positions of the envelope weight relative to the exciter weight and the exciter shaft.
  • a motor which is connected directly (eg via a flange connection or splined shaft connection) or indirectly (that is to say via at least one drive intermediate piece) to the exciter shaft.
  • a motor is in particular a hydraulic motor.
  • the axis of rotation of the motor with the axis of rotation of the exciter shaft is aligned or coaxial, to allow the most direct and thus structurally simple transmission of the drive power of the motor to the exciter shaft.
  • a soil compaction device comprising at least one vibration exciter according to the invention.
  • a soil compaction device is z.
  • a hand-held roller device or a roller device with a driver's cab wherein at least one compression bandage of this soil compaction device by means of at least one inventive Vibration exciter can be acted upon by vibrations.

  • Fig. 3b further illustrates that the excitation shaft 110 is not formed continuously along the rotation axis D g , but has a front member 110 a and a rear member 110 b, which are separated by a release F in the axial direction.
  • This release F greatly facilitates the assembly of the envelope weight 130 with the exciter weight assembly 120 and exciter shaft 110, as will be described in more detail below.
  • the release F also results in substantially no mass being arranged in the axial space between the front bearing point 131 and the rear bearing point 132, as a result of which, in addition, a weight distribution which is advantageous with regard to vibration generation is obtained.
