Abstract: A vibrator for generating vibrations. An exciter cell having rotationally drivable unbalanced masses that are rotatably supported in an exciter cell housing and having an adjustment unit for adjusting the phase position of the unbalanced masses relative to one another. The adjustment unit is configured as a planetary gearing that has at least two input trains to which the unbalanced masses of the exciter cell are coupled that are adjustable in phase relative to one another and that has an adjustment input train for changing the phase position of the output trains of the planetary gearing.

Abstract: The present invention relates to a drive for reaching a desired position of a component such as of a rotor blade, a crane tower, a superstructure and the like, having at least two drive elements that are in toothed engagement with one another and of which at least one is drivable from a drive source and the other is connectable to the component, and having a lubricating device for lubricating the drive elements, wherein at least one lubricant passage for the supply of lubricant to a meshing tooth pair is led through one of the drive elements. It is proposed to effect the supply of the lubricant by a distributor that is connected upstream of the lubricant passage integrated in the drive element and to control the connection between a supply passage of the distributor and the at least one lubricant passage integrated in the drive element by a relative movement between the drive element and the distributor.

Abstract: A working machine including a working assembly that can be driven by an engine, with the engine being connectable to the working assembly via a power branching transmission including a first mechanical power branch and a second electric or hydraulic power branch, the first and second power branches being combined by a summation transmission that can be coupled to the working assembly on the output side and provides a variable transmission ratio between the first mechanical power branch and the working assembly that can be adjusted by the rotational speed of the second electric or hydraulic power branch. A blocking device is provided for blocking the variability of the transmission ratio that can be adjusted between the first mechanical power branch and the output side of the summation transmission by the rotational speed of the second electric or hydraulic power branch.
