Abstract

A housing assembly for a rock crusher having an eccentric shaft. The housing assembly has an interior side and an exterior side and comprises a first housing portion having an inner side, an outer side, and a plurality of grooves and being removably attached to the rock crusher, and a second housing portion having a plurality of grooves and being removably attached to the first housing portion. The housing assembly also comprises an inner ring having at least one inner ring housing groove and at least one inner ring pitman groove and being disposed on the interior side of the housing assembly, and an outer ring having at least one outer ring groove and being disposed on the exterior side of the housing assembly. The housing assembly is disposed around the eccentric shaft. A method for removably housing a bearing assembly on a rock crusher.

Claims (34)

1. A rock crusher having a base, a pitman, and an eccentric shaft with a fixed end and a float end, and a housing assembly, said housing assembly comprising:

a. a fixed end housing assembly, said fixed end housing assembly having an interior side and an exterior side and comprising:

(i) a first fixed end housing portion, said first fixed end housing portion having an inner side and an outer side and being adapted to be removably attached to the rock crusher;

(ii) a second fixed end housing portion, said second fixed end housing portion being adapted to be removably attached to the first fixed end housing portion;

wherein the fixed end housing assembly comprises a plurality of fixed end housing assembly grooves;

b. an inner spacer, said inner spacer being disposed on the inner side of the first fixed end housing portion;

c. an outer spacer, said outer spacer being disposed on the outer side of the first fixed end housing portion;

d. a fixed end inner ring, said fixed end inner ring having at least one fixed end inner ring housing groove and at least one fixed end inner ring pitman groove and being disposed on the interior side of the fixed end housing assembly;

e. a fixed end outer ring, said fixed end outer ring having at least one fixed end outer ring groove and being disposed on the exterior side of the fixed end housing assembly;

f. a float end housing assembly, said float end housing assembly having an interior side and an exterior side and comprising:

(i) a first float end housing portion, said first float end housing portion being adapted to be removably attached to the rock crusher;

(ii) a second float end housing portion, said second float end housing portion being adapted to be removably attached to the first float end housing portion;

wherein the float end housing assembly comprises a plurality of float end housing assembly grooves;

g. a float end inner ring, said float end inner ring having at least one float end inner ring housing groove and at least one float end inner ring pitman groove and being disposed on the interior side of the float end housing assembly;

h. a float end outer ring, said float end outer ring having at least one float end outer ring groove and being disposed on the exterior side of the float end housing assembly;

wherein the fixed end housing assembly is disposed around the eccentric shaft adjacent to the fixed end of the eccentric shaft; and wherein the float end housing assembly is disposed around the eccentric shaft adjacent to the float end of the eccentric shaft; and

wherein the at least one fixed end outer ring groove and the at least one float end outer ring groove are disposed substantially parallel to the eccentric shaft; and wherein the fixed end housing assembly and the float end housing assembly are disposed outside the pitman and the base.

2. The housing assembly of claim 1 wherein the assembly is adapted to removably retain a bearing assembly.

3. The housing assembly of claim 1 wherein the plurality of fixed end housing assembly grooves, the at least one fixed end inner ring housing groove, and the at least one fixed end outer ring groove form a labyrinth seal.

4. The housing assembly of claim 1 wherein the plurality of float end housing assembly grooves, the at least one float end inner ring housing groove, and the at least one float end outer ring groove form a labyrinth seal.

5. The housing assembly of claim 1 wherein the first fixed end housing portion comprises a plurality of holes.

6. The housing assembly of claim 1 wherein the first float end housing portion comprises a plurality of holes.

7. The housing assembly of claim 1 wherein the fixed end housing assembly comprises a channel.

8. The housing assembly of claim 1 wherein the float end housing assembly comprises a channel.

9. The housing assembly of claim 1 wherein the plurality of fixed end housing assembly grooves are machined into the fixed end housing assembly.

10. The housing assembly of claim 1 wherein the plurality of float end housing assembly grooves are machined into the float end housing assembly.

11. The housing assembly of claim 1 wherein the at least one fixed end inner ring housing groove is machined into the fixed end inner ring.

12. The housing assembly of claim 1 wherein the at least one fixed end outer ring groove is machined into the fixed end outer ring.

13. The housing assembly of claim 1 wherein the at least one float end inner ring housing groove is machined into the float end inner ring.

14. The housing assembly of claim 1 wherein the at least one float end outer ring groove is machined into the float end outer ring.

15. The housing assembly of claim 1 wherein the fixed end inner ring and the fixed end outer ring are adapted to rotate with the eccentric shaft.

16. The housing assembly of claim 1 wherein the first fixed end first housing portion and the second fixed end second housing portion are stationary when the eccentric shaft rotates.

17. The housing assembly of claim 1 wherein the float end inner ring and the float end outer ring are adapted to rotate with the eccentric shaft.

18. The housing assembly of claim 1 wherein the first float end first housing portion and the second float end housing portion are stationary when the eccentric shaft rotates.
