Abstract

A generator rotor refurbishing system includes a cutting tool configured to cut generator rotor bars. The cutting tool includes a guide track configured and disposed to be fixedly mounted relative to a generator rotor and a cutting head block moveably mounted relative to the guide track. The cutting tool is configured and disposed to produce a fixed depth cut through a generator rotor bar. A cleaning system is configured for substantially simultaneously cleaning first and second opposing surfaces and first and second opposing edges of the generator rotor bar. The cleaning system includes a guide member and a cleaning assembly moveably mounted to the guide member. The cleaning assembly includes a plurality of cleaning members arranged to clean each of first and second opposing surfaces and first and second opposing edges of the generator rotor bar.

First claim

What is claimed is:

1. A generator rotor refurbishing system comprising:
a cutting tool configured to cut generator rotor bars, the cutting tool including:
a guide track configured and disposed to be fixedly mounted relative to a generator rotor;
a cutting head block moveably mounted relative to the guide track, the cutting head block including a blade element movable in a direction substantially perpendicular to the movement of the cutting block head within the guide track to achieve a first fixed depth, substantially square cut; and
an adjustment block adapted for installation between the cutting block head and the guide track,

whereby the cutting tool is configured and disposed for a second cutting operation to produce a second cut through another generator bar arranged below the generator rotor bar without moving the guide track, the second cut being laterally and axially off-set from the first cut.

2. The generator rotor refurbishing system according to claim 1 , wherein the second cut comprises a second fixed depth substantially square cut.

3. The generator rotor refurbishing system according to claim 1 , wherein cutting tool includes a main block and a clamping block mounted to the guide track, the main block being configured and disposed to cooperate with the clamping block to grip a generator rotor bar.

4. The generator rotor refurbishing system according to claim 3 , wherein the cutting tool includes a surface contact block mounted to the main block, the surface contact block being configured and disposed to rest upon a generator rotor bar.

5. The generator rotor refurbishing system according to claim 4 , wherein the cutting tool includes a surface contact block adjustment member configured and disposed to shift the surface contact block relative to the main block.

6. A generator rotor refurbishing system comprising:
a cutting tool configured to cut generator rotor bars, the cutting tool including:
a clamping apparatus comprising a first clamping surface and a second clamping surface;
a guide track configured and disposed to be fixedly mounted relative to a generator rotor;
a cutting head block moveable along the guide track perpendicular to the first clamping surface and the second clamping surface and including a blade element movable in a direction substantially perpendicular to the movement of the cutting block head within the guide track to achieve a first fixed depth, substantially square cut; and
an adjustment block adapted for installation between the cutting block head and the guide track,

whereby the cutting tool is configured and disposed for a second cutting operation to produce a second cut through another generator bar arranged below the generator rotor bar without moving the guide track, the second cut being laterally and axially off-set from the first cut.

7. The generator rotor refurbishing system of claim 1 , further comprising:
a guide block disposed between the cutting head block and the guide track, the guide block including a slot member.

8. The generator rotor refurbishing system of claim 7 , wherein the guide track includes a guide slot into which the slot member extends.

9. The generator rotor refurbishing system of claim 8 , further comprising:
a pair of rib elements disposed between the slot member and a surface of the guide slot.

10. The generator rotor refurbishing system of claim 6 , further comprising:
a guide block disposed between the cutting head block and the guide track, the guide block including a slot member.

11. The generator rotor refurbishing system of claim 10 , wherein the guide track includes a guide slot into which the slot member extends.

12. The generator rotor refurbishing system of claim 11 , further comprising:
a pair of rib elements disposed between the slot member and a surface of the guide slot.

13. A cutting tool comprising:
a guide track including a guide slot;
a cutting head block moveably mounted relative to the guide track, the cutting head block including a straight-edged blade element movable in a direction substantially perpendicular to the movement of the cutting block head within the guide track, the straight-edged blade element being configured and disposed to produce a first fixed depth cut;
a guide block disposed between the cutting head block and the guide track, the guide block including a slot member extending into the guide slot;
a pair of rib elements disposed between the slot member and a surface of the guide slot; and
an adjustment block adapted for installation between the cutting block head and the guide track,
whereby the cutting tool is configured and disposed for a second cutting operation to produce a second cut through another generator bar arranged below the generator rotor bar without moving the guide track, the second cut being laterally and axially off-set from the first cut.
