Abstract
A swivel joint for coupling a first conduit to a second conduit includes a swivel bearing comprising a body of fluid. The swivel bearing eliminates the creation and transmission of torsional and shear loads when one or both of the conduits are axially loaded.
Claims26
A swivel joint for coupling a first conduit to a second conduit, comprising:
- a sleeve coupled to the second conduit;
- a tubular member interconnecting the sleeve and the second conduit;
- a body coupled to the first conduit adapted to receive a portion of the sleeve;
- a retaining member coupled to the body, including a counterbore adapted to receive another portion of the sleeve;
- a chamber defined by the sleeve and the retaining member;
- and
- a body of fluid contained within the chamber.
A swivel joint for coupling a first conduit to a second conduit, comprising:
- a sleeve coupled to the second conduit;
- a body coupled to the first conduit adapted to receive a portion of the sleeve;
- a retaining member coupled to the body, including a counterbore adapted to receive another portion of the sleeve;
- a chamber defined by the sleeve and the retaining member;
- a body of fluid contained within the chamber;
- and
- the chamber being inclined relative to the axes of the conduits.
A swivel joint for coupling a first conduit to a second conduit, comprising:
- a first member connected to the first conduit;
- a retaining member connected to the first member and having a portion extending in a spaced relation to the first member;
- a sleeve connected to the second conduit and disposed in the space between the first member and the retaining member;
- a tubular member interconnecting the sleeve and the second conduit;
- a chamber extending between the sleeve and the retaining member;
- and
- a fluid disposed in the chamber for transmitting axial loads between the first and second conduits without inducing torsional loads.
The swivel joint of claims further comprising a plurality of bolts extending through aligned openings in the first member and the retaining member to connect the retaining member to the first member.
A swivel joint for coupling a first conduit to a second conduit, comprising:
- a first member connected to the first conduit;
- a retaining member connected to the first member and having a portion extending in a spaced relation to the first member;
- a sleeve connected to the second conduit and disposed in the space between the first member and the retaining member;
- a chamber extending between the sleeve and the retaining member;
- a fluid disposed in the chamber for transmitting axial loads between the first and second conduits without inducing torsional loads;
- and
- the chamber being inclined with respect to the axes of the conduits.
A joint for connecting two conduits, the joint comprising a first member connected to one of the conduits, a second member connected to the other conduit, means for establishing a chamber for containing fluid between the conduits so that the fluid transmits axial loads between the members, and interconnecting a tubular member between the second member and the respective other conduit.
The joint of claim;
- wherein the second conduit extends through a central opening formed in the third member.
A joint for connecting two conduits, the joint comprising a first member connected to one of the conduits, a second member connected to the other conduit, means for establishing a chamber for containing fluid between the conduits so that the fluid transmits axial loads between the members, and the chamber being inclined with respect to the axes of the conduits.
A method of connecting two conduits comprising connecting one of the conduits to a first member, connecting the other conduit to a second member, establishing a chamber containing fluid between the conduits so that the fluid transmits axial loads between the members, and inclining the chamber with respect to the axes of the conduits.
