Definitions

  • the invention relates to a vibration generator, comprising at least two wave groups, on which at least two imbalance groups are arranged and which are connected to at least one drive, that they are driven at different speeds, wherein means are provided to change the phase position of at least two imbalance groups to each other, whereby a directed feed is achieved.
  • vibrators are used to bring objects such as profiles into the ground or to pull them out of the ground or to compact soil material.
  • the soil is stimulated by vibration and thus reaches a "pseudo-liquid state".
  • By static load the pile can then be pressed into the ground.
  • the vibration is characterized by a linear movement and is generated by pairwise counter-rotating imbalances.
  • the vibration generators are linear vibration exciters whose centrifugal force is generated by rotating imbalances.
  • the size of the unbalance is also called a static moment.
  • the course of the velocity of the linear vibration exciter corresponds to a periodically recurring function, in particular a sine function. Due to the sinusoidal course of the force generated by means of the rotating unbalanced masses a temporally offset alternately acting in and against the direction of advance drive is generated.
  • a vibration generator is for example au DE 196 39 789 A1 known.
  • U1 discloses to achieve an increased propulsion at a constant speed of the imbalances by changing the phase position of the imbalances.
  • the invention aims to remedy this situation.
  • the invention is based on the object to provide a vibrator which allows depending on the task a directional force in both ramming and pulling direction. According to the invention, this object is solved by the features of the characterizing part of patent claim 1.
  • a vibration generator is created, which allows depending on the task a directed force in the forward or in the pulling direction.
  • the means for adjusting the effective direction comprise a pivot motor, via which the phase shift of at least two Unbalance groups is mutually variable.
  • the at least two imbalance groups are connected via gears to the pivot motor, wherein at least one imbalance group with the stator and at least one imbalance group are connected to the rotor of the swing motor.
  • the swivel motor is advantageously a rotary-wing pivoting motor.
  • the swing motor may also be a swivel motor with coarse thread.
  • two wave groups are arranged, wherein the wave groups are connected to the at least one drive, that the speed of the first wave group is half the speed of the second wave group and wherein the ratio of the static moments of the wave groups provided with the imbalance groups between six to one and ten to one.
  • the static moment of the first wave group is eight times as large as the static moment of the second wave group.
  • a pronounced force peak is effected in the advancing direction.
  • three wave groups are arranged on which at least three unbalance groups are arranged, wherein the wave groups are connected to the at least one drive, that the speed of the first wave group half the speed of the second wave group and one third of the speed of the third Is wave group and wherein the ratio of the static moments of the imbalance groups provided with the imbalance groups is substantially 100: 16.64: 3.68.
  • the maximum-acting force is increased by a further pronounced force peak in the forward direction. This causes a further increase in energy efficiency, combined with an acceleration of the piling process.
  • four wave groups are arranged on which at least four unbalance groups are arranged, wherein the wave groups are connected to the at least one drive such that the ratio of the rotational speeds of the wave groups to each other is substantially 1: 2: 3: 4 and wherein the ratio of the static moments of the imbalance groups provided with the imbalance groups is substantially 100: 18.72: 5.6: 1.38.
  • the vibration generator chosen as the embodiment are designed as vibrator gear.
  • Such vibrators essentially consist of a housing in which gears provided with gears are rotatably mounted.
  • the gears are each provided with imbalance masses.
  • Such Vibratorgetriebe with rotatably mounted imbalance masses are the expert, for example from the DE 20 2007 006 283 U1 known.
  • the following explanation of the embodiments is essentially limited to the arrangement of waves and imbalance masses.
  • the shafts 11, 12 of the shaft group 1 are provided with toothed wheels 112, 122, on which imbalance masses 111, 121 are arranged.

  • the shafts 21, 22 of the shaft group 2 are as it were provided with gears 212, 222, on which similar imbalance masses 211, 221 are arranged.
  • the gears 112, 122, 212, 222 are designed such that upon rotation, the rotational speed of the shafts 21, 22 of the shaft group 2 is twice as large as the rotational speed of the shafts 11, 12.
  • the imbalance masses 111, 121, 211, 221 are arranged such that the static moment of the Wave group 1 is eight times larger than the static moment of wave group 2.
  • a pivot motor 5 is arranged, whose stator has a gear 51 and whose rotor has a gear 52.
  • the wave groups 1, 2 are connected to each other via the swing motor 5 such that the gear 112 of the shaft 11 is engaged with the gear 55 of the swing motor 5; the gears 212, 222 of the shaft group 2 are connected to the gear 51 of the swing motor 5 in engagement.
  • the swing motor 5 is a rotary wing pivoting motor with a wing.
  • the wave groups 1, 2 of three shafts 11, 12, 13, 21, 22, 23 are formed, which are each provided with imbalance masses 111, 121, 131, 211, 221, 231.
  • the gears 112, 122, 132, 212, 222, 232 of the shafts 11, 12, 13, 21, 22, 23 are in turn chosen such that upon rotation, the waves of the shaft group 2 have twice the speed, the waves of the wave group. 1
  • the number of waves of the wave groups 1, 2 can also be chosen differently.
  • an additional shaft 24 is added with corresponding imbalance mass 241.

  • the gears 112, 122, 132 of the shaft group 1 with the gear 51 of the stator of the swing motor 5 in engagement and the gears 212, 222, 223 of the shaft group 2 are engaged with the gear 52 of the rotor of the swing motor 5.
  • a switching of the direction of action is possible.
  • staggered arrangement of the waves of the wave group 2 in turn a more compact height can be achieved (see. FIG. 5 b) ).
  • FIG. 6 is a modified structure of the aforementioned arrangement according to FIG. 5 shown, which allows a significant reduction in length, but in which instead of six waves eight waves are required, but this is reflected in a lower load on the shaft bearings and advantages in terms of recoverable centrifugal force, suitability for high speeds and lower sensitivity large angular acceleration brings with it.
  • an additional speed stage whose unbalance rotate at three times speed can be used.
  • FIG. 7 is such an arrangement based on the transmission concept according to FIG. 5 shown. This falls slightly wider, since the lower large gear 132, which drives the two juxtaposed shafts 31, 32, is shifted relative to the transmission center.
