Rotor for a turbomachine

Abstract

The invention refers to a rotor for a turbomachine, wherein the rotor has a vibration reduction device which is formed in such a way that it damps vibrations of the rotor which emerge during operation of the turbomachine. The damping is achieved by means of a rolling body inside the vibration reduction device, wherein the rolling body is arranged with capability of movement along a track surface.

       13 . A rotor for a turbomachine having a rotational axis, comprising:
 a housing arranged on a surface of the rotor, wherein the housing has an interior portion;   a track surface formed on an interior surface of the housing; and   a body arranged on the track surface where the rolling body damps vibrations of the rotor that emerge during operation of the turbomachine by movement of the body on the track surface.   
   
   
       14 . The rotor as claimed in  claim 13 , wherein the rolling body is a ball. 
   
   
       15 . The rotor as claimed in  claim 13 , wherein the rolling body is a cylinder. 
   
   
       16 . The rotor as claimed in  claim 13 , wherein the track surface is curved. 
   
   
       17 . The rotor as claimed in  claim 13 , wherein the track surface is convexly curved relative to the rotational axis of the rotor. 
   
   
       18 . The rotor as claimed in  claim 17 , wherein the housing contains a fluid. 
   
   
       19 . A rotor for a turbomachine having a rotational axis, comprising:
 a housing arranged on a surface of the rotor, wherein the housing has an interior portion;   a support element contained within the interior portion of the housing;   an oscillating arm attached to the support element; and   an oscillating mass attached at an end of the oscillating arm, wherein the oscillating arm and mass are formed in a pendulum like manner.   
   
   
       20 . The rotor as claimed in  claim 19 , wherein the oscillating arm is arranged to provide rotation of the oscillating arm around a point of rotation. 
   
   
       21 . The rotor as claimed in  claim 19 , wherein the oscillating arm is arranged to provide rotation of the oscillating arm around an axis of rotation. 
   
   
       22 . A rotor for a turbomachine having a rotational axis, comprising:
 a housing arranged on a surface of the rotor, wherein the housing has an interior portion;   a track surface formed on an interior surface of the housing;   a support element contained within the interior portion of the housing;   an oscillating arm attached to the support element;   an oscillating mass attached at an end of the oscillating arm, wherein the oscillating arm and mass are formed in a pendulum like manner; and   a body arranged on the track surface where the rolling moves along the track surface.   
   
   
       23 . The rotor as claimed in  claim 22 , wherein the track is convexly curved relative to the rotational axis of the rotor. 
   
   
       24 . The rotor as claimed in  claim 22 , wherein the oscillating arm is pivotably to the support element.
