Abstract

Certain exemplary embodiments provide a rotating machine assembly comprising a rotor machine assembly including a shaft, a plurality of laminations shrink fit around the circumference of the shaft, and weights affixed therebetween the laminations for balancing the rotating machine assembly.

Claims (36)

1. A system for balancing of a rotating device comprising:

a rotor;

a shaft provided within the rotor;

a first lamination shrink fit around the shaft;

a second lamination shrink fit around the shaft; and

a weight secured between the first and second lamination for balancing the rotating device, wherein the first lamination includes an aperture having a same shape as the weight and the second lamination includes an aperture having a circular shape, and wherein the aperture of the first lamination and the weight have a trapezoidal shape.

2. A system for balancing of a rotating device comprising:

a rotor;

a shaft provided within the rotor;

a first lamination shrink fit around the shaft;

a second lamination shrink fit around the shaft: a;d

a weight secured between the first and second lamination for balancing the rotating device, wherein the weight includes a drilled aperture to receive a fastener.

3. A system for balancing of a rotating device comprising:

a rotor;

a shaft provided within the rotor;

a first lamination shrink fit around the shaft;

a second lamination shrink fit around the shaft; and

a weight secured between the first and second lamination for balancing the rotating device, wherein an aperture of the first lamination and an aperture of the second lamination have a trapezoidal shape.

4. A system for balancing of a rotating device comprising:

a rotor;

a shaft provided within the rotor;

a first lamination shrink fit around the shaft;

a second lamination shrink fit around the shaft; and

a weight secured between the first and second lamination for balancing the rotating device, wherein the fastener is inserted through an aperture of the weight, through an aperture of the first lamination and through a second lamination to secure the weight therebetween.

5. The system of claim 4 , wherein the fastener is secured by a fastening securement element.

6. The system of claim 5 , wherein the fastening securement element is a nut.

7. A method for balancing of a rotating device comprising:

threading a fastener through an aperture of a balancing weight;

inserting the fastener within an aperture of a first lamination of the rotating device;

threading the fastener through an aperture of a second lamination to secure the balancing weights between the first and second laminations to balance and prevent vibration of the rotating device.

8. The method of claim 7 , further comprising:

shrink fitting the first and second laminations to a shaft.

9. The method of claim 7 , wherein the aperture of the balancing weight and the aperture of the first lamination have a trapezoidal shape.

10. The method of claim 7 further comprising:

threading a securement element upon the end of the fastener to provide a secure the tightly secure the balancing weights between the first and second laminations.

11. The method of claim 10 wherein the securement element is a nut.
