Abstract: A vibration generator comprises two unbalance shafts, which are positively coupled in a contra-rotative manner and whose relative phrase position can be shifted by a phase shifting device. Each of the unbalance shafts supports a main unbalance mass and a partial unbalance mass that can move in relation thereto. The position of the partial unbalance masses on the respective unbalance shafts can be actively altered within a large range by adjusting devices. The resulting vibration vector generated by the vibration generator can set in a diverse manner with regard to direction and magnitude.

Abstract: The invention relates to vibration generator for a soil compacting device referred to as a towed vibrating device. The vibration generator has two parallels arranged unbalanced shafts that each support a fixed and a freely rotating unbalanced mass. An unbalance adjusting device enables the position of both freely rotating unbalanced masses to be adjusted in such a manner that, during a maximum unbalance action of one of the unbalanced shafts, the unbalance action on the other unbalanced shaft is minimized. The unbalance adjusting device can alter the position of the unbalanced masses whereby rendering possible a to-and-fro movement of the soil compacting device or a compaction when stationary.

Abstract: A vibration exciter for soil compacting devices, e.g., for a vibration plate, comprises unbalanced shafts. These unbalanced shafts are parallel or coaxial to one another, can be driven in opposite directions with the same rotational speed, and each supports a stationary unbalanced mass and an unbalanced mass that can rotatably move relative to the unbalanced shaft. The relative position of a respective moving unbalanced mass with regard to the unbalanced shaft supporting the same can be adjusted by an adjusting device so that the centrifugal forces produced by the unbalanced masses during the rotation of the unbalanced shafts are entirely canceled out in every position of rotation of the unbalanced shafts. This makes it possible, among other things, to effect a change in the relative position so that the magnitude of a total centrifugal force resulting from the unbalanced masses is proportional to an advancing speed of the soil compacting device.

Abstract: The invention relates to a controller for an unbalanced mass adjusting unit in a vibration exciter. Said controller comprises an adjusting piston for changing the relative position of unbalanced masses in the vibration exciter that is coupled to a reference piston. The position of a piston rod of the reference piston is detected by a pressure sensor and is furnished to a controller in the form of a position signal. The controller compares the position signal with an operating signal given by an operator and generates a control signal with which the position of a selector valve that controls the oil supply to or the oil discharge from the reference piston can be changed.

Abstract: A readjusting device used to modify the functional parameters of an oscillator which comprises at least one rotatable unbalanced mass which is supported by a rotationally driveable shaft is provided with a rotationally mounted adjusting member on said shaft in order to modify the above-mentioned functional parameters and with an adjusting pin which is associated with the adjusting member, can be readjusted in an axial direction inside the shaft and which is arranged in such a way that it can rotate with the shaft. The adjusting pin which can be actuated by a controllable, non-rotating stamp and said stamp are disposed in an axial direction of the shaft in such a way that a crowned contour and a counter surface traversing the rotational axis of the shaft at a right angle touch each other in the center thereof relative to the axis of rotation.

Abstract: A vibration exciter for a ground compacting devices such as a vibratory plate comprises unbalanced shafts which are arranged parallel or coaxial to one another, which can be driven in counter-rotation with the same rotational speed, and which each carry at least one centrifugal weight, whereby the phase position of the centrifugal weights can be adjusted by a phase adjusting device in such a manner that the vertical components of the centrifugal forces generated by the centrifugal weights are cancelled out in each rotational position. At the same time, the horizontal components of the centrifugal forces are correspondingly added in the same direction. This phase position prevents the vibratory plate, when stationary, from introducing any vertical vibration into the ground to be compacted, but enables it to introduce shear stresses via a ground contact plate into the ground, preferably an asphalt surface, in order to compact cracks and pores.

Abstract: A soil compacting device has a damping system which couples an upper mass and a lower mass together with a spring system in a vibration system. The damping properties of the damping system can be modified while the device is in operation. Therefore, when the soil compacting device passes over soils having different properties, it can constantly be adjusted in an optimal manner to the ground underneath it by acting on the vibration properties of the overall vibration system.

Abstract: A vibration generator for generating directed vibrations in a compacting device includes a housing and a first and second flyweight shafts rotatably supported in the housing and extending parallel at a distance to one another. The flyweight shafts have a respective flyweight connected thereto. A first and second intermediate shafts are rotatably supported in the housing and extend parallel to and between the first and second flyweight shafts. Gear wheels positive-lockingly connect the first and second intermediate shafts to one another, the first intermediate shaft to the first flyweight shaft, and the second intermediate shaft to the second flyweight shaft. In this manner, the first intermediate shaft and the first flyweight shaft, respectively, the second intermediate shaft and the second flyweight shaft rotate in opposite directions. One of the intermediate shafts has connected thereto two gear wheels, with one being coupled to the first flyweight shaft and another coupled to the second flyweight shaft.

Abstract: A vibrator including two axially parallel, interlocking, counterrotating unbalanced shafts. Both the phase relationship of the unbalanced shafts, and hence the direction of the vector of the directed vibrations, and the value of m.r., and hence the displacement of the vibrations of the compaction element connected to the vibrator, are variable. To this end, the unbalanced shafts are coupled by a hub that is disposed in a rotatable yet axially fixed manner on one of the unbalanced shafts and that has, in the wall surrounding the shaft, a groove that extends along the unbalanced shaft. A pin that is fixedly secured to the unbalanced shaft and that can be adjusted by a servomotor engages slidingly in the groove. The direction of operation of the driven unbalanced shaft is reversible. Each unbalanced shaft has an eccentric part that is fixedly mounted thereon and an eccentric part that is freely rotatable thereon over a predetermined angular range between extreme positions that are delimited by stops.

Abstract: A chopper circuit is provided for driving of electromagnets and/or step motor coils (8;26) in particular for a matrix printer, where the inductivity of the coil generates in connection with the applied voltage a maximum current, which current, however, is set lower by desired factor, whereby the current ripples (7a) are generated by chopping. These current ripples (7a) can be changed, that is, set to an optimum value depending on frequency inductivity and resistance of an electromagnetic coil (8) or, respectively, of a magnet coil winding (26).

Abstract: An oscillator or vibration exciter for soil or road tampers or compacting devices. Unbalanced shafts are journalled parallel to each other in a common housing, and are driven in opposite directions by gears which mesh with each other and are installed on the unbalanced shafts. Each shaft supports a centrifugal weight rigidly coupled therewith. One gear is rigidly connected with its unbalanced shaft, while the other gear is rotatably arranged on its unbalanced shaft and is coupled therewith in such a way that it can be shifted in the direction of rotation by shift pins, which are anchored in a slide piece which can be axially shifted in this unbalanced shaft. The shift pins project outwardly through a longitudinal slot in the unbalanced shaft. This other rotatable gear, on both sides, has stop faces which extend nearly radially as well as axially, and point in the same rotational direction. A shift pin is provided on each side of this gear, one end of each shift pin projecting from the unbalanced shaft.

Abstract: An imbalance oscillation exciter having two imbalance weights arranged on each of two axially parallel or coaxial imbalance-weight carriers positively rotatably coupled with one another and rotating counter to each other or in the same direction. At least one of these imbalance-weight carriers comprises a shaft, whereby the imbalance-weight carriers are coupled with each other by a hub for continuous opposite rotation for the purpose of changing the phase position of the imbalance weights. A pin fixed on the shaft slidably engages in a hub groove. The pin is shiftable along a shaft slot extending at an incline to the hub groove by means of an adjustment member arranged coaxially in the shaft. The shaft has an axially parallel cylinder chamber open toward one of its end faces and in which the adjustment member is slidable with a piston extension sealed with respect thereto and facing the open side of the cylinder chamber.

Abstract: An unbalance oscillation generator with constant direction of rotation, in which the resultant centrifugal force is variable due to unbalance on the unbalance shaft including two parts adjustable relative to each other and fixable relative to each other in at least two relative angularly spaced positions. The resultant of the two unbalance forces generated by the two parts varies in value in the individual fixable relative angle positions. A control pin displaceable by means of an adjusting rod extending through the unbalance shaft and projecting from the end face of the unbalance shaft either engages a circumferential groove facing the unbalance shaft but located in the axially non-displaceable part of the unbalance weight or engages a recess or cutout branching off from the circumferential groove. The control pin fits with slight play into the recess and is adapted to be arrested in either one of the respective pertaining axial positions.

Abstract: A device for sealing V-belts and pulleys in plate jarring devices, in which a V-belt drive interconnects the drive motor and the unbalance oscillation generator fixedly connected to the bottom plate.
