Abstract

A kit includes an adjustable chock provided with a first component having screw threads and with a second component having screw threads cooperating with the screw threads of the first component and having a lower bearing surface, and with a bearing element provided with a lower bearing surface in contact with an upper bearing surface of the first component, and with an upper bearing surface. The kit further includes at least one friction ring adapted to be mounted against the lower bearing surface of the second component or against the upper bearing surface of the bearing element.

First claim

The invention claimed is:

1. A kit adapted for use in an adjustable chock, the kit comprising:
a first component having a first component upper bearing surface, the first component upper bearing surface comprising a flat, axially outermost, radially extending portion;
a second component threadably engaged with the first component, the second component having a second component lower bearing surface and a second component upper bearing surface, the second component upper bearing surface comprising a radially outermost portion and a radially innermost annular flat portion, the radially outermost portion of the second component upper bearing surface sloping such that an axial length of the second component decreases from a radially outermost point of the radially innermost annular flat portion of the second component upper bearing surface to a radially outermost point of the second component upper bearing surface;
a bearing element provided with a bearing element lower bearing surface in contact with the first component upper bearing surface, the bearing element lower bearing surface not being in contact with the flat, axially outermost, radially extending portion, the bearing element also having a bearing element upper bearing surface; and
a friction ring adapted to be mounted against either one of the groups of the second component lower bearing surface and the bearing element upper bearing surface in a way that eliminates a direct contact of the either one of the group of the second component lower bearing surface and the bearing element upper bearing surface with a corresponding one of the group of a supporting surface and a supported surface.

2. The kit according to claim 1 , wherein a friction coefficient of the friction ring is at least zero point six five (0.65).

3. The kit according to claim 1 , wherein the friction ring comprises a steel substrate.

4. A kit adapted for use in an adjustable chock, the kit comprising:
a first component having a first component upper bearing surface;
a second component threadably engaged with the first component and having a second component lower bearing surface;
a bearing element provided with a bearing element lower surface in contact the first component upper bearing surface, the bearing element having a bearing element upper bearing surface;
a first friction ring adapted to be mounted against the second component lower bearing surface; and
a second friction ring adapted to be mounted against the bearing element upper bearing surface.

5. The kit according to claim 4 , wherein the first friction ring is configured to cover the entire second component lower bearing surface.

6. The kit according to claim 4 , wherein the second friction ring is configured to cover the entire bearing element upper bearing surface.

7. The kit according to claim 4 , wherein the first friction ring has lower and upper first friction ring frontal faces, the lower and upper first friction ring frontal faces each provided with a coating, the coating comprising a layer having a plurality of diamond particles embedded therein.

8. The kit according to claim 7 , wherein the plurality of diamond particles has a mean size of between ten micrometers (10 μm) and fifty-five micrometers (55 μm).

9. The kit according to claim 7 , wherein the plurality of diamond particles occupy between eight percent (8%) and sixty percent (60%) of the layer.

10. The kit according to claim 4 , wherein the second friction ring has lower and upper second friction ring frontal faces, the lower and upper second friction ring frontal faces each provided with a coating comprising a layer having a plurality of diamond particles embedded therein.

11. The kit according to claim 4 , wherein the first friction ring comprises a steel substrate.

12. The kit according to claim 11 , wherein the first friction ring comprises two opposite coatings each having a nickel layer with a plurality of diamond particles embedded therein.

13. The kit according to claim 12 , wherein the second friction ring comprises a steel substrate.

14. The kit according to claim 13 , wherein the second friction ring comprise two opposite coatings each having a nickel layer with a plurality of diamond particles embedded therein.

15. A method for levelling and anchoring a machine to a support, the method comprising the steps of:
providing a first component having a first component upper bearing surface;
threadably engaging a second component with the first component, the second component having a second component lower bearing surface;
positioning a bearing element in contact with the first component such that a bearing element lower surface contacts the first component upper bearing surface, the bearing element having a bearing element upper bearing surface;
positioning first friction ring against the second component lower bearing surface; and
positioning a second friction ring against the bearing element upper bearing surface.

16. The method according to claim 15 , further comprising the step of joining the machine to the support via a fastener which extends through the first friction ring, the second component, the first component, the bearing element, and the second friction ring.

17. The method according to claim 16 , adjusting a relative position of the first component and the second component.

18. The method according to claim 16 , adjusting a relative position of the first component and the bearing element to level the machine.

19. The method according to claim 16 , tightening the fastener so as to secure the relative position between the first component and the second component and to secure the relative position between the first component and the bearing element.

20. A kit adapted for use in an adjustable chock, the kit comprising:
a first component having a first component upper bearing surface;
a second component threadably engaged with the first component, the second component having a second component lower bearing surface;
a bearing element provided with a bearing element lower bearing surface in contact with the first component upper bearing surface, the bearing element also having a bearing element upper bearing surface; and
a friction ring adapted to be mounted against either one of the group of the second component lower bearing surface and the bearing element upper bearing surface, the friction ring being metallic,
wherein the friction ring comprises a steel substrate,
wherein the friction ring comprises two opposite coatings each having a nickel layer with a plurality of diamond particles embedded therein.
