Abstract

Methods of balancing a workpiece, in which the workpiece is rotated about an axis of rotation. The forces and/or torques that result from an unbalance of the workpiece during the rotation of the workpiece are measured, and material is removed from the workpiece to reduce the unbalance. The method includes removal of material from the rotating workpiece during measuring or as the workpiece is continuously rotated between measuring and material removal.

First claim

What is claimed is:

1. A method for balancing a workpiece, comprising
rotating the workpiece about an axis of rotation, wherein the workpiece comprises a balancing disk with a fully-round outer contour;
measuring the forces and/or torques and/or oscillations that result during the rotation of the workpiece from an unbalance of the workpiece; and
removing material of the balancing disk so as to reduce the unbalance and cause the balancing disk to have a non-round outer contour,
wherein the material is removed from the rotating workpiece during said measuring,
wherein the balancing disk is disposed on a shaft of the workpiece, wherein the balancing disk is distinct from and spaced apart from a functional portion of the workpiece along the shaft of the workpiece,
wherein a machining means for removing material of the balancing disk is of movable design, wherein removing material of the balancing disk comprises rough balancing where a first amount of material is removed from the balancing disk and fine balancing where a second amount of material is removed from the balancing disk, with the first amount of material being greater than the second amount of material, wherein the rough balancing and the fine balancing occur at different locations of the balancing disk.

2. The method of claim 1 wherein the material of the workpiece is removed by a defined cutting edge to reduce the unbalance.

3. The method of claim 1 wherein the material of the workpiece is removed in a direction obliquely to the axis of rotation to reduce the unbalance.

4. The method of claim 1 wherein during said removing of material, advancement occurs by way of a relative movement between the workpiece and a machining means.

5. The method of claim 4 wherein during said removing of material of the workpiece to reduce the unbalance, advancement occurs cyclically.

6. The method of claim 1 wherein the balancing disk is one of a plurality of balancing disks of the workpiece that have fully-round outer contours, the material thereof being removed at the same time to reduce the unbalance.

7. The device of claim 1 wherein a machining means for removing material of the balancing disk is of movable design.

8. The device of claim 7 comprising asymmetrically removing material from an axial end face of the workpiece.

9. The method of claim 1 wherein removing material of the balancing disk comprises removing material from a non-functional surface of the balancing disk of the workpiece.

10. The method of claim 1 wherein removing material of the balancing disk comprises rough balancing where a first amount of material is removed from the balancing disk and fine balancing where a second amount of material is removed from the balancing disk, with the first amount of material being greater than the second amount of material, wherein the rough balancing and the fine balancing occur at different locations of the balancing disk.
