Abstract

A rotational coupling including a bearing assembly including a first race rotatably coupled to a second race, wherein the first race is configured to receive a plurality of first fasteners to couple the first race and the bearing assembly to a fluid supply. The rotational coupling also including a connection flange coupled to the second race and configured to receive a plurality of second fasteners to couple the connection flange to the second race. The second race includes a first side facing the connection flange and a second side opposite the first side and facing the first race, wherein the second race includes at least one access aperture configured to enable access to the plurality of first fasteners from the first side to removably couple the bearing assembly to the fluid supply.

First claim

What is claimed is:

1. A discharge device comprising:
a nozzle;
an oscillating monitor configured to oscillate the nozzle between a first angular position and a second angular position; and
a rotational coupling rotatably coupling the oscillating monitor to the nozzle, the rotational coupling comprising:
a bearing assembly including a first race rotatably coupled to a second race, wherein the first race includes is configured to receive a plurality of first fasteners to couple the first race and the bearing assembly to a fluid supply conduit; and
a connection flange coupled to the second race and configured to receive a plurality of second fasteners to couple the connection flange to the second race;
wherein the second race includes a first side facing the connection flange and a second side opposite the first side and facing the first race, wherein the second race includes at least one access aperture configured to enable removal of the plurality of first fasteners from the first side to removably couple the bearing assembly to the fluid supply conduit.

2. The discharge device of claim 1 , wherein a cavity configured to receive a seal is formed between the first race, the second race, and a first side of the fluid supply conduit.

3. The discharge device of claim 1 , further comprising a plurality of bearings configured to facilitate rotation of the first race relative to the second race.

4. The discharge device of claim 1 , wherein the second race includes a groove extending around a periphery of the first side configured to accept a sealing member.

5. The discharge device of claim 4 , wherein the plurality of first fasteners are received in a plurality of first apertures in the fluid supply conduit and a plurality of second apertures in the first race, and wherein the second race includes a plurality of third apertures configured to accept the plurality of second fasteners to couple the connection flange and the second race.

6. The discharge device of claim 1 , wherein the connection flange includes a plurality of fourth apertures configured to accept a plurality of third fasteners to couple the connection flange to a rotational arm.

7. The discharge device of claim 1 , wherein the second race further includes a groove configured to receive a protrusion of the first race that extends into the groove in a same direction as the plurality of first fasteners.

8. The discharge device of claim 1 , wherein the second side of the second race and a corresponding side of the first race interface at a groove and a protrusion.

9. A discharge device comprising:
a nozzle;
an oscillating monitor configured to oscillate the nozzle between a first angular position and a second angular position; and
a rotational coupling rotatably coupling the oscillating monitor to the nozzle, the rotational coupling comprising:
a bearing assembly including a first race rotatably coupled to a second race, wherein the first race includes is configured to receive a plurality of first fasteners to couple the first race and the bearing assembly to a fluid supply conduit; and
a connection flange coupled to the second race and configured to receive a plurality of second fasteners to couple the connection flange to the second race;
wherein the second race includes a first side facing the connection flange and a second side opposite the first side and facing the first race, wherein the second race includes at least one access aperture configured to enable removal of the plurality of first fasteners from the first side;
wherein the second race further includes a groove configured to receive a protrusion of the first race that extends into the groove in a same direction as the plurality of first fasteners.

10. The discharge device of claim 9 , wherein a cavity configured to receive a seal is formed between the first race, the second race, and a first side of the fluid supply conduit.

11. The discharge device of claim 9 , further comprising a plurality of bearings configured to facilitate rotation of the first race relative to the second race.

12. The discharge device of claim 9 , wherein the second race includes a groove extending around a periphery of the first side configured to accept a sealing member.

13. The discharge device of claim 12 , wherein the plurality of first fasteners are received in a plurality of first apertures in the fluid supply conduit and a plurality of second apertures in the first race, and wherein the second race includes a plurality of third apertures configured to accept the plurality of second fasteners to couple the connection flange and the second race.

14. The discharge device of claim 9 , wherein the connection flange includes a plurality of fourth apertures configured to accept a plurality of third fasteners to couple the connection flange to a rotational arm.

15. A discharge device comprising:
a nozzle;
an oscillating monitor configured to oscillate the nozzle between a first angular position and a second angular position; and
a rotational coupling rotatably coupling the oscillating monitor to the nozzle, the rotational coupling comprising:
a bearing assembly including a first race rotatably coupled to a second race, wherein the first race includes is configured to receive a plurality of first fasteners to couple the first race and the bearing assembly to a fluid supply conduit; and
a connection flange coupled to the second race and configured to receive a plurality of second fasteners to couple the connection flange to the second race;
wherein the second race includes at least one access aperture configured to enable removal of the plurality of first fasteners from a first side to removably couple the bearing assembly to the fluid supply conduit;
wherein a second side of the second race and a corresponding side of the first race interface at a groove and a protrusion.

16. The discharge device of claim 15 , wherein the second race includes the first side facing the connection flange and the second side opposite the first side and facing the first race.

17. The discharge device of claim 15 , wherein a cavity configured to receive a seal is formed between the first race, the second race, and a first side of the fluid supply conduit.

18. The discharge device of claim 15 , further comprising a plurality of bearings configured to facilitate rotation of the first race relative to the second race.

19. The discharge device of claim 15 , wherein the second race includes a groove extending around a periphery of the first side configured to accept a sealing member.

20. The discharge device of claim 19 , wherein the plurality of first fasteners are received in a plurality of first apertures in the fluid supply conduit and a plurality of second apertures in the first race, and wherein the second race includes a plurality of third apertures configured to accept the plurality of second fasteners to couple the connection flange and the second race.
