Abstract

A track roller frame assembly for a track type machine is disclosed. The track roller frame assembly includes a first track roller frame and a second track roller frame. The first track roller frame is slidably received in the second track roller frame. The second track roller includes an outer surface and an opening. The track roller frame assembly further includes an assembly for adjusting a gap between the first track roller frame and the second track roller frame. The assembly includes a first plate coupled to the outer surface of the second track roller frame. The assembly further includes a resilient pad extending through the opening of the second track roller frame and abutting the first plate and the first track roller frame.

First claim

What is claimed is:

1. A track roller frame assembly for a track type machine, comprising:
a first track roller frame,
a second track roller frame, the first track roller frame slidably received in the second track roller frame, the second track roller frame having an outer surface and an opening; and
an assembly for adjusting a gap between the first track roller frame and the second track roller frame, the assembly for adjusting the gap including:
a first plate coupled to the outer surface of the second track roller frame;
a resilient pad extending through the opening of the second track roller frame and abutting the first plate and the first track roller frame; and
one or more shims arranged between the first plate and the second track roller frame.

2. The track roller frame assembly of claim 1 , wherein the gap between the first track roller frame and the second track roller frame is adjusted by varying a number of the one or more shims.

3. The track roller frame assembly of claim 1 , wherein the gap between the first track roller frame and the second track roller frame is reduced by removing at least one of the one or more shims.

4. The track roller frame assembly of claim 1 , wherein the gap between the first track roller frame and the second track roller frame is adjusted by varying a thickness of at least one of the one or more shims.

5. The track roller frame assembly of claim 1 , wherein the gap between the first track roller frame and the second track roller frame is reduced by replacing at least one of the one or more shims with one or more shims of lower thickness.

6. The track roller frame assembly of claim 1 further comprising a second plate disposed between the outer surface of the second track roller frame and the first plate.

7. A track type machine, comprising:
a main frame; and
an undercarriage coupled to the main frame, the undercarriage including a track roller frame assembly comprising:
a first track roller frame;
a second track roller frame, the first track roller frame slidably received in the second track roller frame, the second track roller frame having an outer surface and an opening; and
an assembly for adjusting a gap between the first track roller frame and the second track roller frame, the assembly for adjusting the gap including:
a first plate coupled to the outer surface of the second track roller frame;
a resilient pad extending through the opening of the second track roller frame and contacting the first track roller frame and the first plate; and
one or more shims arranged between the first plate and the second track roller frame.

8. The track type machine of claim 7 , wherein the gap between the first track roller frame and the second track roller frame is adjusted by varying a number of the one or more shims.

9. The track type machine of claim 7 , wherein the gap between the first track roller frame and the second track roller frame is reduced by removing at least one of the one or more shims.

10. The track type machine of claim 7 , wherein the gap between the first track roller frame and the second track roller frame is adjusted by varying a thickness of at least one of the one or more shims.

11. The track type machine of claim 7 , wherein the gap between the first track roller frame and the second track roller frame is reduced by replacing at least one of the one or more shims with one or more shims of lower thickness.

12. The track type machine of claim 7 further comprising a second plate disposed between the outer surface of the second track roller frame and the first plate.

13. A track roller frame assembly for a track type machine, comprising:
a first track roller frame,
a second track roller frame, the first track roller frame slidably received in the second track roller frame, the second track roller frame having an outer surface and an opening; and
an assembly for adjusting a gap between the first track roller frame and the second track roller frame, the assembly for adjusting the gap including:
a first plate coupled to the outer surface of the second track roller frame;
a resilient pad extending through the opening of the second track roller frame and abutting the first plate and the first track roller frame;
a second plate disposed between the outer surface of the second track roller frame and the first plate; and
one or more shims arranged between the first plate and the second plate,
wherein a combined thickness of the one or more shims arranged between the first plate and the second plate is varied to adjust the gap between the first track roller frame and the second track roller frame.

14. The track roller frame assembly of claim 13 , wherein the combined thickness of the one or more shims is varied by varying a number of the one or more shims.

15. The track roller frame assembly of claim 13 , wherein the combined thickness of the one or more shims is varied by replacing at least one of the one or more shims with one or more shims of different thickness.
