Abstract

Methods and apparatus for insulating interior walls of lamination slots of dynamo-electric machine components are provided. The relative speeds and sequence of cutting, forming, and inserting a piece of insulation material into the slot of the lamination core of a dynamo-electric machine component may be determined by a central drive mechanism. The central driving mechanism may have a plurality of cams, rotating with a main shaft, to control the translations of cutting, forming and inserting members.

Claims

1. An apparatus for insulating interior walls of lamination slots of dynamo-electric machine components comprising:

a cutting member for cutting a strip of insulation material into a segment having a predetermined length;

a forming member for forming the cut segment of insulation material into a predetermined shape;

an inserting member for inserting the formed segment of insulation material into the lamination slot;

a central control device comprising a single shaft and a first, second, and third plurality of cams coupled to a longitudinal axis of the shaft, wherein the first plurality of cams controls the cutting member, the second plurality of cams controls the forming member, and the third plurality of cams controls the inserting member.

2. The apparatus defined in claim 1, wherein each cam of the first plurality of cams is sufficiently contacted by a roller coupled to at least one arm of a first yoke.

3. The apparatus defined in claim 2, wherein play between the rollers and the first plurality of cams is minimized.

4. The apparatus defined in claim 1, wherein each cam of the second plurality of cams is sufficiently contacted by a roller coupled to at least one arm of a second yoke.

5. The apparatus defined in claim 4, wherein play between the rollers and the second plurality of cams is minimized.

6. The apparatus defined in claim 1, wherein each cam of the third plurality of cams is sufficiently contacted by a roller coupled to at least one arm of a third yoke.

7. The apparatus defined in claim 6, wherein play between the rollers and the third plurality of cams is minimized.

8. An apparatus for insulating interior walls of lamination slots of dynamo-electric machine components comprising:

a cutting member for cutting a strip of insulation material into a segment having a predetermined length;

a forming member for forming the cut segment of insulation material into a predetermined shape;

an inserting member for inserting the formed segment of insulation material into the lamination slot;

a central control device comprising a single shaft and a first, second, and third plurality of cams coupled to a longitudinal axis of the shaft, wherein;

the central control device is enclosed by a casing containing lubricant for lubricating the central control device.

9. An apparatus for insulating interior walls of lamination slots of dynamo-electric machine components comprising:

a cutting member for cutting a strip of insulation material into a segment having a predetermined length;

a forming member for forming the cut segment of insulation material into a predetermined shape;

an inserting member for inserting the formed segment of insulation material into the lamination slot;

a central control device comprising a single shaft and a first, second, and third plurality of cams coupled to a longitudinal axis of the shaft, wherein;

the central control device is enclosed by a casing containing lubricant for lubricating the central control device; and

there are a plurality of protruding members that implement, at least in part, the control of the cutting member and the forming member, wherein the plurality of protruding members protrude from the same side of the casing.

10. The apparatus defined in claim 9, wherein the insulation material is external to the casing.
