Self-leveling thrust bearing retainer
A thrust bearing includes a bearing retainer including a first ring and a second ring radially spaced from the first ring, the first ring and the second ring defining an annular passageway therebetween, and at least two bearing pad retaining arrangements extending from a first surface of the second ring, each bearing pad retaining arrangement defining a retaining channel therein, and at least two bearing pads circumferentially spaced within the bearing retainer. The bearing pads may be held within the bearing retainer via the bearing pad arrangements.
1. A thrust bearing, comprising:
a bearing retainer comprising:
a first ring and a second ring radially spaced from the first ring, the first ring and the second ring defining an annular passageway therebetween; and
at least two bearing pad retaining arrangements extending from an uppermost surface of the second ring, each bearing pad retaining arrangement defining a retaining channel therein; and
at least two bearing pads circumferentially spaced within the bearing retainer,
wherein the bearing pads are held within the bearing retainer using the bearing pad retaining arrangements.
2. The thrust bearing as claimed in claim 1 , wherein each bearing pad comprises at least one retaining member provided in each side surface of the bearing pad.
3. The thrust bearing as claimed in claim 2 , wherein the at least one retaining member comprises a dowel pin.
4. The thrust bearing as claimed in claim 3 , wherein the at least one retaining member comprises a spring-loaded dowel pin.
5. The thrust bearing as claimed in claim 1 , wherein the retaining channel comprises:
an insertion channel; and
a holding channel,
wherein the insertion channel extends substantially perpendicularly to the holding channel.
6. The thrust bearing as claimed in claim 5 , wherein at least one retaining member provided in each side surface of the bearing pads is inserted into the insertion channel via an interference fit.
7. The thrust bearing as claimed in claim 5 , wherein at least one retaining member provided in each side surface of the bearing pads is held within the holding channel via a clearance fit.
8. The thrust bearing as claimed in claim 5 , wherein a diameter of the holding channel is greater than a diameter of at least one retaining member provided in each side surface of the bearing pads.
9. The thrust bearing as claimed in claim 1 , wherein the retaining channel is formed as an inverted T-slot.
10. The thrust bearing as claimed in claim 1 , wherein at least one aperture is defined in an outer circumferential surface of the first ring.
11. The thrust bearing as claimed in claim 10 , wherein each bearing pad comprises at least one retaining member provided in an inner surface of the bearing pad, and
wherein the at least one retaining member provided in the inner surface of the bearing pad is inserted into the at least one aperture defined in the outer circumferential surface of the first ring.
12. The thrust bearing as claimed in claim 11 , wherein a diameter of the at least one aperture defined in the outer circumferential surface of the first ring is greater than a diameter of the at least one retaining member provided in the inner surface of the bearing pad.
13. The thrust bearing as claimed in claim 11 , wherein the at least one retaining member provided in the inner surface of the bearing pad is inserted into the bearing pad via a friction fit.
14. A thrust bearing retainer, comprising:
a first ring and a second ring radially spaced from the first ring, the first ring and the second ring defining an annular passageway therebetween; and
at least two bearing pad retaining arrangements extending from an uppermost surface of the second ring, each bearing pad retaining arrangement defining a retaining channel therein.
15. The thrust bearing retainer as claimed in claim 14 , wherein the retaining channel is formed as an inverted T-slot.
16. The thrust bearing retainer as claimed in claim 14 , wherein the retaining channel comprises:
an insertion channel; and
a holding channel,
wherein the insertion channel extends substantially perpendicularly to the holding channel.
17. The thrust bearing retainer as claimed in claim 14 , wherein at least one aperture is defined in an outer circumferential surface of the first ring.
