Track slide assembly and crawler shoe system
Specially fabricated wear plugs are designed for selective insertion within machined holes in a track slide, which decrease friction material below the surface of the track slide. The wear plugs decrease friction between adjoining parts of the track slide assembly and reduce wear caused through use of the track slide in various applications. Methods of fabricating the wear plugs are also provided.
1. A track slide assembly, comprising:
a medial portion comprising a first proximal end and a distal second end;
the medial portion further comprising a semi-arcuate outer surface extending between the first proximal end and the second distal end, wherein the semi-arcuate outer surface comprises a plurality of machined holes;
at least one wear plug configured to be inserted and retained within each of the plurality of machined holes, wherein the at least one wear plug comprises a length substantially the same as the depth of the plurality of machined holes;
wherein the at least one wear plug is inserted and retained within each of the plurality of machined holes such that the at least one wear plug is flush with the semi-arcuate outer surface of the medial portion of the assembly.
2. The track slide assembly of claim 1 wherein the plurality of holes comprises from 24 machined holes to 48 machined holes.
3. The track slide assembly of claim 1 wherein the plurality of machined holes comprises 32 machined holes.
4. The track slide assembly of claim 1 wherein the plurality of machined holes are uniformly distributed about the semi-arcuate outer surface and between the first proximal end and the second distal end of the medial portion of the assembly.
5. The track slide assembly of claim 1 wherein the plurality of machined holes are non-uniformly distributed about the semi-arcuate outer surface and between the first proximal end and the second distal end of the medial portion of the assembly.
6. The track slide assembly of claim 1 wherein the plurality of machined holes comprise multiple, distinct orientations relative to the semi-arcuate outer surface of the medial portion of the assembly.
7. The track slide assembly of claim 6 wherein the orientation of the plurality of machined holes are normal to the semi-arcuate outer surface of the medial portion of the assembly.
8. The track slide assembly of claim 1 wherein the at least one wear plug is retained in each of the plurality of machined holes by an interference connection.
9. The track slide assembly of claim 1 wherein the at least one wear plug is retained in each of the plurality of machined holes through use of an adhesive or bonding agent.
10. The track slide assembly of claim 1 wherein the at least one wear plug is selectively removeable from each of the plurality of machined holes.
11. The track slide assembly of claim 1 wherein the at least one wear plug is selectively replaceable in each of the plurality of machined holes.
12. The track slide assembly of claim 10 wherein the at least one wear plug is inspected or measured after selectively removal from each of the plurality of machined holes.
13. The track slide assembly of claim 1 wherein the at least one wear plug is retained in each of the plurality of machined holes by a friction connection.
14. The track slide assembly of claim 1 wherein the at least one wear plug is one (1) inch in diameter and approximately three-quarters (¾) inch in depth.
15. The track slide assembly of claim 1 wherein the at least one wear plug is a friction reduction material.
16. The track slide assembly of claim 1 wherein the at least one wear plug is comprised of a graphite material, a polyurethane, a polyethylene, a PTFE, a UHMW or a synthetic material.
17. The track slide assembly of claim 1 wherein the track slide assembly is attached to a crawler assembly associated with a piece of heavy machinery.
18. The track slide assembly of claim 17 , wherein multiple track slide assemblies are attached to the crawler assembly.
