Abstract
A swivel comprising a first swivel member comprising a first load shoulder and a second swivel member comprising a second load shoulder. The first and second swivel members are rotatable relative to each other. A deformable bearing component is provided within a cavity defined between the first and second load shoulder. The deformable bearing component facilitates load transmission between the first and second load shoulders and is deformable to accommodate variations in alignment between the first and second load shoulders.
Claims15
A swivel comprising:
- a first swivel member comprising a first load shoulder;
- a second swivel member comprising a second load shoulder, wherein the first and second swivel members are rotatable relative to each other,
- wherein the first and second load shoulders define a primary relative alignment, with the first and second load shoulders being positioned in the primary relative alignment when the swivel is not under load, and wherein the first and second load shoulders are configured to be misaligned from the primary relative alignment in at least one of an axial direction, a radial direction, and at an inclined angle;
- a deformable bearing component provided within a cavity defined between the first and second load shoulders, wherein load applied between the first and second load shoulders is transmitted via the deformable bearing component, the deformable bearing component being deformable to accommodate variations in alignment between the first and second load shoulders,
- wherein the deformable bearing component accommodates relative rotation between the first and second swivel members, and a bearing interface is defined between the deformable bearing component and at least one of the first and second load shoulders.

A method of operating a swivel, the method comprising:
- applying an axial load in a first relative direction to a swivel comprising first and second swivel members which are arranged to be rotatable relative to each other;
- wherein a deformable bearing component is provided in a cavity defined between a first load shoulder of the first swivel member and a second load shoulder of the second swivel member, wherein the first and second load shoulders define a primary relative alignment with the first and second load shoulders being positioned in the primary relative alignment when the swivel is not under load, and wherein the first and second load shoulders are configured to be misaligned from the primary relative alignment in at least one of an axial direction, a radial direction, and at an inclined angle, and wherein the deformable bearing component accommodates relative rotation between the first and second swivel members, with a bearing interface being defined between the deformable bearing component and at least one of the first and second load shoulders;
- and
- deforming the deformable bearing component to accommodate variations in alignment between the first and second load shoulders.
