    Tamping unit for tamping sleepers on a track
    TECHNICAL FIELD The invention relates to a tamping unit for tamping sleepers on a track, comprising a tamping unit with opposing tamping tools mounted on a tool carrier, each of which is connected to an auxiliary drive for generating an auxiliary movement, an eccentric drive being provided for generating a vibration movement is. In addition, the invention relates to a method for tamping sleepers of a track by means of a tamping unit.
    PRIOR ART For maintenance of a track or after a track renewal there is usually a need to compact a ballast bed. In addition to hand tampers, tamping units are known for this purpose, which are arranged on track construction machines. While the track is being tamped, the track-laying machine moves along the track, with tamping pick attached to the tamping unit being lowered into threshold compartments and provided.
    [03] A tamping unit is exposed to extremely high loads. Particularly when plunging into the ballast bed and then compacting the ballast below a threshold, high load changes occur constantly, which put a heavy load on the vibration drive. Even between the tamping processes, the tamping unit is considerably stressed by the continuously operating vibration drive and the vibration transmitted to the tamping tools.
    [04] Darning units for tamping sleepers of a track are already widely known, such as. B. by AT 350 097 B. As a vibration exciter is a rotatable eccentric shaft on which the auxiliary drives are articulated to transmit the vibrations to the tamping pick. With this design, the vibration amplitude on the tamping tools is fixed.

    Summary of the invention [05] The object of the invention is to provide an improvement over the prior art for a tamping unit of the type mentioned in the introduction. Another object is to present a method for tamping sleepers on a track using an improved tamping unit.
    [06] According to the invention, this object is achieved by a tamping unit according to claim 1 and a method according to claim 10. Dependent claims indicate advantageous embodiments of the invention.
    [07] The invention provides that the eccentric drive is arranged in a sealed housing with oil bath lubrication and that at least one vibration transmission element protrudes from the housing, which is connected to an auxiliary drive or both auxiliary drives. This improves the lubrication of the eccentric drive including the eccentric shaft. In addition, the arrangement according to the invention allows the auxiliary drives to be replaced without opening the housing. In the event of signs of wear, the tamping unit can therefore be quickly repaired.
    In an advantageous embodiment of the invention it is provided that the housing with the at least one vibration transmission element is designed as a module mounted with detachable connecting elements. This modular design makes it easy to replace the eccentric drive. The housing together with the eccentric shaft and vibration transmission element can be used as a spare part (assembly) and there is easy maintenance and repair options on site at the construction site. There is also the possibility of cost-effectively retrofitting existing tamping units with the assembly. Furthermore, by combining different module components, different tamping units can be put together for various requirements.
    [09] A further improvement of the device according to the invention provides that the tamping unit has several tamping units of identical design for / 18th
    1704
    3/10 includes simultaneous tamping of multiple sleepers. Thanks to this flexible design and variable combination of tamping units, the tamping units are perfectly adapted to the conditions in work and customer requirements. In addition, an enormous cost reduction is given by a modular construction.
    [10] In a first advantageous variant of the invention, a first vibration transmission element is connected to the one auxiliary drive and a second vibration transmission element is connected to the other auxiliary drive. As a result, different vibration amplitudes can be transmitted with the auxiliary drives if required.
    It makes sense if the housing is arranged above the auxiliary drives. With this arrangement, it is possible to vary an oscillation amplitude at a lower end of the tamping tools by vertically displacing the housing together with the eccentric shaft.
    Another advantageous variant of the invention provides that a vertically oriented vibration transmission element is connected to the two auxiliary drives. This reduces the moving masses on the tamping unit and thus reduces noise. In addition, only a sealed housing bushing for the one vibration transmission element is to be provided.
    It is advantageous if the housing is arranged below the auxiliary drives. This results in a very low overall height of the tamping unit for a compact design of the tamping unit. In addition, the housing bushing for the vibration transmission element is arranged at the top and the lower housing half is closed. The lower half of the housing thus forms a sealed oil pan, which prevents oil lubrication leaks.
    [14] An advantageous further development of the invention is provided when the length of the vibration transmission element is adjustable by means of an adjustment drive. This changes the kinematic arrangement of the eccentric drive and the auxiliary drives. The vibration amplitude generated by the eccentric drive then causes a changed / 18
    1704
    4.10
    Vibration amplitude at the lower ends of the tamping tools. In this way, the vibration amplitude effective in the ballast bed is precisely adapted to a required work situation.
    A further advantageous embodiment provides that the housing is designed to be vertically displaceable relative to the tool carrier by means of an adjustment drive. This allows the oscillation amplitude at the lower ends of the tamping tools to be adjusted in a structurally simple manner.
    The method according to the invention provides that a connection point of the respective auxiliary drive with the associated vibration transmission element is displaced in the vertical direction in order to vary an oscillation amplitude at a lower end of the tamping tools. As a result, the vibration amplitude of the tamping tools is set smaller in a non-lowered position and larger during an immersion process. This leads to energy savings and noise reduction during the tamping process.

    DESCRIPTION OF THE EMBODIMENTS [18] The tamping unit 2 shown in FIG. 1 for tamping sleepers 3 of a track 4 is part of a tamping unit 1 and comprises two opposing tamping tools / 18 mounted on a tool carrier 5

    6, which are each connected to an auxiliary drive 7. Above the auxiliary drives 7, an eccentric drive 8 is arranged in a sealed housing 9 with an oil bath lubrication 10. An eccentric shaft 12 rotates about an eccentric axis 11, on which two vibration transmission elements 13 are mounted like a connecting rod.
    The vibration transmission elements 13 protrude from the bottom of the housing 9, a longitudinal axis of the respective vibration transmission element 13 including an angle of approximately 40 degrees with a vertical. With this kinematic arrangement, a vertical displacement of the housing 9 causes a maximum change in an oscillation amplitude 17 at a lower end 18 of the tamping tools 6. One end of the respective vibration transmission element 13 is articulated to an auxiliary drive 7. The housing 9 is sealed at an outlet 15 via a spherical seal 14. The respective add-on drive 7 is assigned to the stuffing tool 6, which lies opposite the associated vibration transmission element. In the side view according to FIG. 1, the axes of action of the two auxiliary drives 7 thus cross over one another. An offset arrangement or an exemption prevents the ordering drives 7 from interfering with their movement or from causing disruptive bending elements.
    The tamping tools 6 are each rotatably mounted on the tool carrier 5 about a pivot axis 16. The housing 9 together with the vibration transmission elements 13 is detachably arranged on the tool carrier 5 via connecting elements 31.
    In order to make it possible to adjust the vibration amplitude 17 at the lower ends 18 of the tamping tools 6, the housing 9 can be displaced in a vertical direction 19 via an adjustment drive 20. The adjustment drive 20 is designed as a spindle drive, for example. The releasable connecting element 31 are then arranged on a guide part of the housing 9 or are themselves designed as vertical guides.
    The vibration amplitude 17 which is most suitable for penetration into a ballast bed is at an angle 21 of approximately 70 degrees between the longitudinal axis of the respective vibration transmission element 13/18
    1704
    6/10 and the effective axis of the associated auxiliary drive 7 reached. Fig. 2 shows the kinematic arrangement in a simplified line representation. In this position, the vibration amplitude 17 is approximately 5 mm. If the tamping unit 1 is in a raised position, the housing 9 is raised via the adjustment drive 20 and the angle 21 is increased in order to save energy and reduce noise. At 90 degrees, the slightest vibration is transmitted to the auxiliary drive 7 and the oscillation amplitude 17 goes to zero.
    [24] FIG. 3 shows a simplified sectional view through the housing 9 of the stuffing unit 2 along the section line A-A in FIG. 1. The eccentric shaft 12 is arranged in the housing 9 by means of bearings 22 so as to be rotatable about the eccentric axis 11. The vibration transmission elements 13 are mounted on the eccentric shaft 12, e.g. with rolling bearings, not shown. A first eccentric 23 is formed on the eccentric shaft 12, by means of which the first vibration transmission element 13 can be set in vibration via a connecting rod eye 24. In addition, two eccentrics 25 are arranged, by means of which the second vibration transmission element 13 can be set in vibration opposite to the first vibration transmission element 13 via a connecting rod eye 26.
    [25] Each vibration transmission element 13 has a coupling rod 27 which is guided in the housing 9 at an exit point 15 by means of the associated spherical seal 14. In order to prevent the ingress of dust and impurities, the exit point 15 is additionally covered by a sleeve 28.
    4 shows a tamping unit 2 with an eccentric drive 8 including housing 9 arranged underneath the auxiliary drives 7. A tamping tool 6 is rotatably mounted on the swiveling tool carrier 5 on a swivel axis 16. From the eccentric drives 8 only a vibration transmission element 13 protrudes, on which both auxiliary drives 7 are articulated. The vibration transmission element 13 is mounted in a guide 29 so as to be displaceable in the vertical direction 19 on the tool carrier 5 in order to transmit the vibration from the eccentric drive 8 to the auxiliary drives 7.

    7/10 [27] In this embodiment, a connecting rod 30 with a lower connecting rod eye is mounted on the eccentric shaft 12. An upper connecting rod eye transmits a translatory vibration movement to the vibration transmission element
    13. In this case, the vibration transmission element 13 can comprise a coupling rod 27 which can be adjusted lengthwise by means of a drive in order to change the kinematic arrangement of the auxiliary cylinders 7 and thus to set the vibration amplitude 17 at the lower end 18 of the tamping tools 6.
    [28] As an alternative to this, the housing 9 together with the eccentric drive 8 for the adjustment of the vibration amplitude 17 can be mounted on the tool carrier 5 so that it can be adjusted in height by means of an adjustment drive 20. By changing the kinematic arrangement of the auxiliary drives 7, an angle 21 changes between an active axis of the auxiliary drive 7 and the longitudinal axis of the vibration transmission element 13. The more acute this angle 21 is set, the greater the vibration amplitude transmitted to the tamping tools 6 via the auxiliary drives 7 ,
    5 shows a detailed view of the eccentric drive 8 in the variant according to FIG. 4. In the housing 9, the eccentric shaft 12 is rotatably mounted with bearings 22. On a sealed housing bushing, the eccentric shaft 12 is guided to the outside for coupling to a rotary drive.
    [30] The lower connecting rod eye of the connecting rod 30 is mounted on an eccentric section of the eccentric shaft 12, the bearing not being shown for the sake of clarity. The vibration generated by the eccentric shaft 12 is transmitted to the vibration transmission element 13 by means of the connecting rod 30.
    6 shows an exploded drawing of the eccentric drive 8 together with the housing 9, the eccentric shaft 12, the bearings 22, the connecting rod 30 and a lower section of the vibration transmission element 13.
    [32] The compact design of the tamping unit 2 according to the invention allows a combination of identical units 2 in a tamping unit for simultaneous tamping of several sleepers 3. An exemplary embodiment for three sleepers 3 is shown in FIG. 7. Here, tamping units 2 are assembled into a 3-sleeper unit , The neighboring / 18
