Abstract

High temperature compliant wheels for an inspection robot are described. An example wheel may have a first non-ferrous wheel enclosure including a first outer surface having a serration texture, a second non-ferrous wheel enclosure including a second outer surface having the serration texture, and a magnetic hub interposed between the first non-ferrous wheel enclosure and the second non-ferrous wheel enclosure

First claim

What is claimed is:

1. A wheel for a drive module of an inspection robot, comprising:
a first non-ferrous wheel enclosure comprising a first outer surface having a first serration texture;
a second non-ferrous wheel enclosure comprising a second outer surface having a second serration texture;
a magnetic hub interposed between the first non-ferrous wheel enclosure and the second non-ferrous wheel enclosure;
a first inter-cover interposed between the first non-ferrous wheel enclosure and the magnetic hub, wherein the first inter-cover is structured to guide a magnetic flux of the magnetic hub; and
a diffusion barrier axially interposed between the first inter-cover and the magnetic hub.

2. The wheel of claim 1 , wherein the first non-ferrous wheel enclosure and the second non-ferrous wheel enclosure each comprise aluminum.

3. The wheel of claim 1 , wherein the first non-ferrous wheel enclosure and the second non-ferrous wheel enclosure each comprise at least one of zinc or bronze.

4. The wheel of claim 1 , wherein the first non-ferrous wheel enclosure and the second non-ferrous wheel enclosure each comprise at least one of Poly Urethane (PU), a fluoroelastomer, or ethylene propylene diene terpolymer (EPDM).

5. The wheel of claim 1 wherein at least one of the first or second serration texture comprises a plurality of horizontal serrations comprising a serration pitch.

6. The wheel of claim 1 , wherein the magnetic hub comprises a rare earth metal.

7. The wheel of claim 6 , wherein the magnetic hub comprises a neodymium magnet.

8. The wheel of claim 1 , further comprising: a second inter-cover interposed between the second non-ferrous wheel enclosure and the magnetic hub, wherein the first inter-cover and the second inter-cover are each structured to guide a magnetic field of the magnetic hub.

9. The wheel of claim 8 , where the first inter-cover comprises a first carbon steel plate and the second inter-cover comprises a second carbon steel plate.

10. The wheel of claim 9 , wherein the first carbon steel plate or the second carbon steel plate are coated with an anti-corrosion coating.

11. The wheel of claim 1 , wherein the first inter-cover is axially interposed between the first non-ferrous wheel enclosure and the magnetic hub.

12. The wheel of claim 1 , wherein the first inter-cover comprises a ferromagnetic material.

13. The wheel of claim 12 , wherein the ferromagnetic material comprises carbon steel.

14. The wheel of claim 1 , wherein the diffusion barrier comprises at least one of a coating, a surface hardening, or a non-metallic cover.

15. The wheel of claim 12 , wherein the first non-ferrous wheel enclosure comprises a metallic material, the wheel further comprising the diffusion barrier interposed between the first inter-cover and the first non-ferrous wheel enclosure.

16. The wheel of claim 15 , wherein the diffusion barrier comprises at least one of a coating, a surface hardening, or a non-metallic cover.

17. The wheel of claim 1 , wherein the first non-ferrous wheel enclosure and the second non-ferrous wheel enclosure each comprise a metallic material, the wheel further comprising the diffusion barrier axially interposed between the first non-ferrous wheel enclosure and the magnetic hub and a second diffusion barrier axially interposed between the second non-ferrous wheel enclosure and the magnetic hub.

18. A kit, comprising:
a plurality of wheel enclosures comprising a plurality of operating characteristics, the plurality of wheel enclosures comprising at least two wheel enclosures comprising a serration texture on an outer surface;
a magnetic hub structured to be interposed between two of the plurality of wheel enclosures on an axle;
an inter-cover interposed between the at least two wheel enclosures and the magnetic hub, wherein the inter-cover is structured to guide a magnetic flux of the magnetic hub; and
a diffusion barrier axially interposed between the inter-cover and the magnetic hub.

19. The kit of claim 18 , wherein the plurality of operating characteristics comprises a temperature threshold and a hardness value.

20. The kit of claim 18 , wherein the at least two wheel enclosures comprising the serration texture on the outer surfaces are structured to be incorporated into an inspection robot and to contact an inspection surface having a high temperature.

21. The kit of claim 20 , wherein the high temperature is a temperature greater than 300 degrees Fahrenheit.

22. The kit of claim 18 , wherein the at least two wheel enclosures each comprise aluminum.

23. The kit of claim 18 , wherein the at least two wheel enclosures each comprise at least one of zinc or bronze.

24. The kit of claim 18 , wherein the magnetic hub comprises a rare earth metal, and
a neodymium magnet.

25. The kit of claim 18 , further comprising:
the inter-cover axially interposed between the at least two wheel enclosures and the magnetic hub.

26. The kit of claim 18 , wherein the at least two wheel enclosures each comprise a metallic material, the kit further comprising a diffusion barrier interposed between each of the at least two wheel enclosures and the magnetic hub.

27. A wheel for a drive module of an inspection robot, comprising:
a first non-ferrous wheel enclosure comprising a first outer surface;
a second non-ferrous wheel enclosure comprising a second outer surface;
a magnetic hub interposed between the first non-ferrous wheel enclosure and the second non-ferrous wheel enclosure;
a first inter-cover interposed between the first non-ferrous wheel enclosure and the magnetic hub, wherein the first inter-cover is structured to guide a magnetic flux of the magnetic hub; and
a diffusion barrier axially interposed between the first inter-cover and the magnetic hub.

28. The wheel of claim 27 , wherein the first inter-cover is axially interposed between the first non-ferrous wheel enclosure and the magnetic hub.

29. The wheel of claim 27 , further comprising: a second inter-cover interposed between the second non-ferrous wheel enclosure and the magnetic hub, wherein the first inter-cover and the second inter-cover are each structured to guide a magnetic field of the magnetic hub.

30. The wheel of claim 29 , further comprising a second diffusion barrier axially interposed between the second inter-cover and the magnetic hub.

31. The wheel of claim 30 , wherein the diffusion barrier and the second diffusion barrier each comprises at least one of a coating, a surface hardening, or a non-metallic cover.
