Definitions
- the present invention relates to a soil compaction device with vibration drive, the vibration drive for generating a directed vibration movement at least two in opposite directions synchronously rotating imbalance exciter shafts arranged having.
- soil compaction devices exist in particular from road rollers; the same principle can also be applied to Use plate vibrators.
- Known soil compaction devices have, for example two unbalance exciter shafts arranged horizontally next to each other which, by changing their phase position, generates different Enable compression and drive directions. Since the two Excitation waves, however, have different directions of rotation, they must be spaced sufficiently apart, to prevent the unbalance from colliding. This leads to one correspondingly large space requirements.
- the three unbalance exciter shafts have, which are not next to each other, but are aligned one behind the other, the two outer ones Unbalance exciter shafts rotate in the same direction and pass them through the middle one Unbalance exciter shaft, which is designed as a hollow shaft, with each other are connected.
- the middle unbalance exciter shaft receives the required opposite direction of rotation, it has to reverse the direction of rotation via a separate gear arrangement to one of the two outer unbalance exciter shafts. This too requires an enlarged installation space adapted to this.
- the present invention has for its object the known Soil compacting devices with regard to the arrangement of their Improve unbalance excitation shafts in such a way that they are optimized by Mark installation conditions.
- both imbalances are divided into two and their unbalance parts are each two separate ones Assigned excitation shafts rotating in the same direction to each other are such that the two unbalance parts of the first unbalance on axial mutually aligned excitation waves are arranged that between the two excitation waves the second unbalance is provided, and that the two unbalance parts of the second unbalance are parallel to each other and extends to the excitation waves of the first unbalance extending Excitation waves are arranged.
- the excitation wave of one of the two unbalance parts of the first unbalance directly to the exciter shaft of at least one unbalance part of the second Coupled unbalance is that the excitation waves of both unbalance parts the second unbalance directly to the exciter shaft of an unbalance part of the first unbalance are coupled, and that the drive shaft of the vibration drive which is an unbalance part of the first unbalance part of the drives the exciter shaft assigned to the first unbalance, this exciter shaft, assigned to the two unbalance parts of the second unbalance Exciter waves drives, and one of the two excitation waves the second Unbalance that assigned to the other unbalance part of the first unbalance Exciter shaft drives.
- FIG 1 the structure of a vibration exciter of a soil compaction device shown, in particular four imbalance exciter shafts 1, 2, 3, 4 can be seen, which via a drive shaft 5 are connected to a vibration drive 6.
- Every unbalance excitation shaft 1 to 4 has an associated unbalance weight 11, 12, 13, 14 on, with the unbalance weights 11 and 14 of the unbalance exciter shafts 1 and 4 on the one hand and the unbalance weights 12 and 13 of the unbalance exciter shafts 2 and 3, on the other hand, each in the same orientation are arranged to each other in order to thereby add to a to enable first unbalance A or second unbalance B, both Generate total unbalances each with equal centrifugal forces.
- the unbalance exciter shaft 1 which rotates counterclockwise, points on the end of a gear 21 with a gear 22 of the unbalance exciter shaft 2 and a gear 23 of the unbalance exciter shaft 3 is engaged and both imbalance exciter shafts as a result drives in the opposite direction of rotation, i.e. clockwise.
- the unbalance exciter shaft 3 faces the gear 23 opposite End face another gear 23a, which with a Gear 24 of the unbalance exciter shaft 4 meshes and the exciter shaft 4 in the opposite direction, i.e. in the same direction as the Exciter shaft 1 drives.
- Figure 2 is the reference position for the pivoting of the frame shown, in which the frame is not opposite the drum is pivoted and the two excitation shafts 2 and 3 of the second Imbalance are arranged vertically one above the other.
- Figure 3 shows a position of the frame 7, in which this by 45 ° is pivoted relative to the reference position.
- the present invention thus offers the advantage that the total unbalance is distributed over a total of four excitation waves can be, which on the one hand increases the limit speeds and secondly the centrifugal force by using heavier unbalance weights can enlarge.
- the invention is distinguished Soil compacting device due to optimized installation conditions of the associated excitation waves.
