Definitions

  • the invention relates to a device for generating directed vibrations.
  • the structure can be a vibrating table for concrete compaction or a working device, e.g. a vibrating plate for soil compaction, act.
  • a vibrating table for concrete compaction
  • a working device e.g. a vibrating plate for soil compaction
  • the directional vibrations are predominant by electrically / electronically or mechanically synchronized vibrators or also generated by pendulum vibrators.
  • the vibrators are two counter-rotating centrifugal weights, their opposing centrifugal components cancel each other out while the plane perpendicular to the plane spanned by the axes of rotation of the centrifugal weights standing centrifugal forces add up to a resulting force and the vibration cause.
  • the centrifugal weights are synchronized with sometimes considerable Effort in a mechanical, electrical or electronic way. To the appearance of harmful forces in a direction transverse to the actual direction of vibration Avoiding is a considerable precision in the synchronization required.
  • Such a device is known from GB-A-2 103 333.
  • the one described The device has, among other things, inflatable chambers, the changeable ones Stiffness the strength of the vibration generated by flyweights on a console determine.
  • the invention is therefore based on the object of specifying a device with which generates directional vibrations with reasonable design effort and can be added to a structure.
  • a device for generating directed vibrations is characterized by at least two flyweights with essentially the same m * r, which are mutually independent at essentially the same speed in opposite directions can be driven to rotate about an axis parallel to one another: a largely rigid one Carrier on which the at least two flyweights are rotatably mounted; and by a console to which the carrier can be fastened via a bracket such that the carrier is movable relative to the console.
  • this is a particularly preferred embodiment of the invention characterized in that the carrier relative to the console in the direction of the generated directed vibration as well as in a direction perpendicular to the direction of vibration and is movable perpendicular to the axes of rotation of the flyweights.
  • the vibration to be generated is perpendicular to one through the Axes of rotation of the flyweights aligned plane.
  • the holder has at least one spring element for transmitting the movement of the carrier in Direction of the directed vibration.
  • the spring element can also act as a rubber-elastic element.
  • the holder has at least one spring element for transmitting the Movement of the carrier in the direction perpendicular to the direction of vibration and perpendicular to the axes of rotation of the flyweights. Ensure the spring elements mobility of the carrier in the holder and thus relative to the console, without an unacceptable play between the carrier and the bracket can.
  • the spring elements particularly when coupled with damping elements, effective noise reduction because of the centrifugal weights and their drive generated structure-borne sound vibrations not or only partially on the Console.
  • the stiffness of the spring element or elements is related to the stiffness adapted to the wearer. This ensures that the self-synchronization of the two flyweights regardless of the structure to be excited.
  • a particularly advantageous embodiment of the invention is characterized in that that the bracket has two bracket units attached to the console, between which the carrier is movably received.
  • the bracket units are opposite each other with the carrier arranged therebetween, so that the carrier can be held securely without the need for additional components are.
  • Each of the mounting units advantageously has a spring element into which the carrier is inserted.
  • a drive for each Centrifugal weight arranged on the carrier Since according to the invention the flyweights synchronize independently, it is not necessary to use mechanical, additionally synchronize electrical or electronic components.
  • centrifugal weights axially in half and with the drive motor arranged in between in order to carry out the bearing and To equalize shaft loads on the motors.
  • the console is part of a structure in which the directed vibrations can be initiated. This means either that the bracket or the mounting units are attached directly to the structure to be excited be, or that the console with the bracket and the carrier as a structural unit is attachable to the structure.
  • the structure is a vibrating table or a vibrating plate is because with such a use of the device the previously known replace complex vibration generator with a simpler device to let.
  • the single figure shows a sectional view of a device according to an embodiment the invention.
  • flyweights 1 are in the form of unbalances on axes of rotation 2 rotatably and are each via the axes of rotation 2 by not shown Electric motors driven.
  • two centrifugal weights 1 are provided in the depth direction of the figure, between which the drive motor is arranged. Such arrangements are already known from devices with positively synchronized flyweights, so that no further description is given.
  • the centrifugal weights 1, the axes of rotation 2 and the drive motors are each by means of Supports 3 connected to a common support 4.
  • the carrier 4 is a relative thick steel plate and should be made as rigid as possible.
  • the supports 3 are welded or screwed onto the support 4 and form with the support 4 also the most rigid construction possible.
  • the carrier 4 is on two of its end faces by mounting units forming a mounting 5a and 5b, which are in turn welded to a bracket 6, In other embodiments, the bracket units are not with the console welded, but screwed. Grip over the mounting units 5a and 5b hook-like the carrier 4, being between the carrier 4 and the mounting units 5a, 5b spring elements 7 are inserted.
  • the spring elements 7 can e.g. made of rubber or consist of elastic plastic and, if necessary, also damping properties exhibit.
  • a gap 8 is formed in each case.
  • This gap 8 enables it that the carrier with the unbalance units attached to it when starting of the centrifugal weights 1 move slightly in the horizontal direction with respect to FIG. 1 can what is required for the synchronization of the flyweights 1.
  • the gap 8 can also be filled by a spring element in another embodiment in order to avoid that the carrier 4 directly onto the mounting units 5a, 5b hits.
  • the flyweights 1 are driven by the drive motors in opposite rotation at substantially the same speed brought. Because their product consists of mass the unbalance and radius of the unbalance center is essentially the same, so are those resulting from the rotation Centrifugal forces essentially the same. Due to the opposite rotation, they rise the - seen in relation to Fig. 1 - horizontal components of the centrifugal forces mutually on, while the vertical components in the direction of arrow 9 of the centrifugal forces add and thus generate a directional vibration in the direction of arrow 9.
  • the one directed perpendicular to a plane spanned by the axes of rotation 2 Vibration is on the rigid support 4 and the spring elements 7 on the Transfer console 6 where it can be used in the desired manner.
  • the console 6 can be used on a structure or on a device Work equipment can be attached to the directional vibration in the desired direction Way to initiate. It is also possible that the console 6 is already part of the to be excited Structure or the implement is.
  • the console 6 can be a component a vibration plate for soil compaction or a formwork skin Vibrating table for concrete compaction.
  • the device can not only with the aforementioned vibrating table or the vibrating plate, but also with any other device, where directional vibrations are required.
  • the embodiment shown in the figure has two mounting units 5a, 5b on. In a smaller embodiment of the invention, it is also possible To attach the carrier 4 to the console 6 by only one mounting unit.
