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.
Claims20
A vibrator for generating vibrations comprising:
- rotationally drivable unbalanced masses that are rotatably supported in an exciter cell housing;
- an adjustment unit for adjusting the phase position of the unbalanced masses relative to one another, wherein the adjustment unit comprises a planetary gearing connected to two output trains, wherein the unbalanced masses are coupled to the output trains, and wherein the unbalanced masses are adjustable in phase relative to one another;
- and
- an adjustment input train for adjusting the phase position of the output trains relative to one another,
- wherein at least one of the two output trains is connected to a sun gear, wherein the other of the at least one of the two output trains is connected to a ring gear, and wherein the adjustment input train is connected to a carrier of the planetary gearing.
