Abstract

An apparatus for replacing at least one tooth of a gear includes an elongate anchoring lip having a laterally extending lip body with at least one anchoring hole extending longitudinally therethrough. The lip body is bounded within a lateral plane by transversely spaced front and rear lip faces and laterally spaced first and second side edges. A tooth block extends longitudinally from a selected one of the front and rear lip faces. The tooth block includes at least one replacement gear tooth extending longitudinally therealong. The tooth block is spaced laterally apart from at least one of the first and second side edges, with at least a portion of the lip body extending laterally between the tooth block and the at least one of the first and second side edges.

First claim

We claim:

1. An apparatus for replacing at least one tooth of a gear, the apparatus comprising:
a curved elongate anchoring lip having a lip body defined between first and second side edges of the lip, the lip body extending substantially along, and defining, a lateral direction between the first and second side edges, the lip body having at least one anchoring hole extending therethrough to define a longitudinal direction which is substantially perpendicular to the lateral direction, the lip body including curved front and rear lip faces separated by the lip body to define a transverse direction which is substantially perpendicular to both the lateral and longitudinal directions; and
a tooth block extending in the longitudinal direction from a selected one of the front and rear lip faces, the tooth block including at least one replacement gear tooth extending longitudinally therealong;
wherein the tooth block is spaced apart, in the lateral direction, from at least a chosen one of the first and second side edges, with at least a portion of the lip body extending laterally between the tooth block and the chosen one of the first and second side edges.

2. The apparatus of claim 1 , being integrally formed as a unitary structure.

3. The apparatus of claim 1 , wherein the anchoring lip is substantially planar.

4. The apparatus of claim 1 , wherein the front and rear lip faces are concavely curved, toward the tooth block.

5. The apparatus of claim 1 , wherein front and rear lip faces are convexly curved, away from the tooth block.

6. The apparatus of claim 1 , wherein the anchoring lip is a partial rim of a circle, the circle being coincident with a circumference of the gear.

7. The apparatus of claim 1 , wherein the tooth block is suspended longitudinally from the front lip face.

8. The apparatus of claim 1 , wherein the tooth block is spaced laterally apart from both of the first and second side edges, with a portion of the lip body cantilevered outward from each lateral extent of the tooth block.

9. The apparatus of claim 1 , wherein the at least one anchoring hole includes a plurality of anchoring holes located in predetermined hole locations spaced laterally apart along the anchoring lip, the predetermined hole locations corresponding to positions of fastening apertures on the gear.

10. The apparatus of claim 1 , wherein the at least one replacement gear tooth includes a plurality of replacement gear teeth extending longitudinally along the tooth block, each replacement gear tooth at least partially mimicking a configuration of a native gear tooth of the gear.

11. The apparatus of claim 1 , wherein the replacement gear tooth is transversely spaced from the front lip face.

12. The apparatus of claim 1 , wherein a rear block face of the tooth block, oppositely facing from the replacement gear tooth, is substantially smooth and is curved corresponding to a curve of the front lip face.

13. The apparatus of claim 1 , wherein a rear block face of the tooth block, oppositely facing from the replacement gear tooth, intersects an underside of the anchoring lip at a filleted edge.

14. The apparatus of claim 1 , wherein at least a portion of the tooth block is located adjacent an underside of the anchoring lip, with the replacement gear tooth protruding transversely past the front lip face.

15. The apparatus of claim 1 , wherein the replacement gear tooth completely supplants a corresponding native gear tooth of the gear which is configured to be replaced.

16. The apparatus of claim 1 , wherein the portion of the lip body which extends laterally between the tooth block and at least one of the first and second side edges is adapted for overlapping at least a portion of the gear in a circumferential direction defined by a body of the gear.
