Bearing system
A bearing system including a first member having an outer surface wherein at least a portion of the outer surface includes a plurality of plateaus and a plurality of indentations, a dry-film lubricant at least partially filling at least one of the plurality of indentations, and a second member having a mating surface to the outer surface of the first member wherein the second member configured to move past the first member.
1. A bearing system comprising:
a first member having an outer surface wherein at least a portion of the outer surface comprises a plurality of plateaus and a plurality of indentations;
a dry-film lubricant at least partially filling at least one of the plurality of indentations; and
a second member configured for moving past the first member, wherein a distance between a first pair of adjacent indentations differs from a distance between second pair of adjacent indentations.
2. The bearing system of claim 1 , wherein the first member is a floating bearing and the second member is a gear tooth set.
3. The bearing of claim 1 , wherein the dry-film lubricant covers at least a portion of the plurality of plateaus.
4. The bearing of claim 1 , wherein the dry-film lubricant fills each of the plurality of indentations, and defines a layer covering each of the plateaus.
5. The bearing system of claim 1 , wherein at least a portion of the outer surface of the first member does not include an indentation thereon.
6. The bearing system of claim 1 , wherein the second member comprises steel.
7. The bearing system of claim 1 , wherein the dry-film lubricant comprises a lower load carrying capacity than the first member.
8. The bearing system of claim 1 , wherein the dry-film lubricant includes a higher wear coefficient than the first member.
9. The bearing system of claim 1 , wherein the plurality of indentations includes differing depths.
10. The bearing system of claim 1 , wherein the plurality of indentations include multiple cross section defining differing shapes.
11. The bearing system of claim 1 , wherein the first member includes an aluminum bronze alloy.
12. The bearing system of claim 1 , wherein the plurality of indentations are produced by laser machining.
13. The bearing system of claim 1 , wherein the mating surface of the second member does not include indentations.
14. The bearing system of claim 1 , wherein at least one of the indentations includes a maximum width greater than a maximum depth of the indentation.
15. The bearing system of claim 1 , wherein the plurality of indentations includes an array of indentations wherein a distance between centers of adjacent indentations is greater than a diameter of each of the indentations.
16. The bearing system of claim 1 , wherein at least one of the indentations includes a concave portion of a floor of the indentation.
17. The bearing system of claim 1 , wherein at least one of the indentations includes sides disposed angled with respect to each other at a non-right angle.
