摘要： The invention concerns an arrangement for providing a pulsing compressive force for soil compaction devices. It comprises a first mass (1), which provides a contact surface (2) for transferring the pulsing compressive force onto the ground surface (3) to be compacted, as well as a second mass (4), which via a spring-damper-system (5, 6) is coupled to the first mass (1) to form a vibrating system (1, 4, 5, 6). Further, it comprises an unbalance exciter (7) by means of which the vibrating system (1, 4, 5, 6) can be excited to vibrate.The second mass (4) in doing so exerts in the static state via the first spring-damper-system (5, 6) a static force in direction of gravity (S1) on the first mass (1). The first mass (1) and the second mass (4) are coupled to one another via the spring-damper-system (5, 6) in such a way that no forces can be transferred from the first mass (1) to the second mass (4) in the direction of gravity (S1) and no forces can be transferred from the second mass (4) to the first mass (1) opposite to the direction of gravity. Furthermore the arrangement is designed such that the coupling of the two masses (1, 4) in the intended operation can be temporarily suspended by a vibratory movement of the second mass (4) opposite to the direction of gravity, the second mass (4) can then in the uncoupled state execute a part of its oscillation path, and the coupling of the masses (1, 4) via the first spring-damper-system (5, 6) is then, following a reversal in direction of the vibratory movement of the second mass (4), re-established.

摘要： A vibration exciter, particularly for a vibration pile driver, includes at least four shafts disposed parallel to one another, on which two outer imbalance masses are disposed, in each instance, between which a central imbalance mass is positioned. The central imbalance mass is mounted on the shaft so as to rotate relative to the outer imbalance masses, in each instance. The imbalance masses of the at least four shafts are combined into two imbalance groups, the imbalance masses of which are all synchronized with one another in torsionally rigid manner, in each instance, wherein not only outer imbalance masses but also inner imbalance masses are provided in each of the two imbalance groups, and wherein a phase shifter is provided, by way of which the phasing of the two imbalance groups relative to one another can be adjusted.

摘要： An eccentric shaft for a compacting machine is rotatable about a rotational axis and includes a fixed and movable eccentric mass where the movable eccentric mass cooperates with the fixed eccentric mass in one of the directions of rotation of the eccentric shaft to partly balance the fixed eccentric mass in the other rotation direction of the eccentric shaft. At least one section of the fixed eccentric mass shows a maximal radial extension (UB) in relation to the rotational axis, limited by an arc-shaped curve, which extends to a circle shape, with the diameter (D) showing a distance (A), between the point (P) on the circle-shaped curve that is located closest to the point of intersection of the rotational axis and the section plane, and the point of intersection, from 0 up to 0.1(D).

摘要： An assembly is provided for vibrating a compacting drum of a compacting machine. The assembly includes a shaft rotatably mountable to a compacting drum of the compacting machine. The centre of mass of the shaft is offset from the geometrical rotation axis of the shaft. An outer eccentric member is arranged outside of the shaft, wherein the centre of mass of the outer eccentric member is offset from the geometrical rotation axis of the shaft. The outer eccentric member is displaceably mounted relative to the shaft for adjustment of the eccentricity of the assembly. An extension of the outer eccentric member in a direction parallel with the geometrical rotation axis of the shaft is at least two times an average extension of the outer eccentric member in a radial direction perpendicular to the geometrical rotation axis of shaft such that a mass of the outer eccentric member forms a distributed load along the geometrical rotation axis of the shaft.
