Apparatus for balancing bodies of revolution

An apparatus for balancing bodies of revolution secured on a shaft, said bodies of revolution having an axis of rotation, a geometric axis and a center of mass, comprising:

• a liquid supply source;
• distributing units mounted coaxially with the body of revolution in measurement planes on both sides of a plane passing through said center of mass of said body of revolution perpendicular to the geometric axis of said body of revolution, a first chamber of each of the distributing units being installed in a first measurement plane and being hydraulically connected with said liquid supply source, conduits of said first chamber of each of the distributing units being provided in a side surface of said first chamber, and ends of said conduits being located inside said first chamber and equidistant from the geometric axis of said body of revolution;
• balancing tanks mounted peripherally within said body of revolution in correction planes on both sides of the plane passing through said center of mass of said body of revolution perpendicular to said geometric axis of said body of revolution, and hydraulically associated with said distributing units,
• each conduit of said first chamber of each of said distributing units being hydraulically associated with respective balancing tanks which are located in the correction plane to the other side of the respective measurement plane containing said distributing unit relative to the plane passing through said center of mass of said body of revolution perpendicular to said geometric axis of said body of revolution,
• each of said balancing tanks and said conduit, hydraulically associated therewith, of each of said distributing units being arranged in planes passing through said geometric axis of said body of revolution to form an angle within the range of 0.degree. to 90.degree., defined by the plane containing said conduit hydraulically associated with said balancing tank, and said angle coinciding in direction with the sense of rotation of said body of revolution;
• and
• pipelines connecting said liquid supply source with said conduits of the first chamber of said distributing units, and connecting said first chambers of said distributing units with said balancing tanks.
