Abstract
An assembly for clamping a tube includes a fitting including a land, a bolt housing, legs, and a tooth on each leg, a band surrounding an axis, contacting the land and formed with holes spaced along the band, and a bolt located in the bolt housing, including helical teeth engaged with said holes for changing a diameter of the band and forcing the tooth toward the band as the band is tightened by rotating the bolt.
Claims13
A tube clamping assembly, comprising:
- a fitting including a land extending circumferentially about a central axis and axially along the axis, the land haying two portions separated by a circumferentially extending gap, a bolt housing integrally connected to both of the portions of the land, a leg integral with and extending from one of the two portions, and a tooth on the leg, both portions of the land, the bolt housing, the leg and the tooth being formed as a single monolithic piece;
- a band surrounding the axis, contacting both portions of the land radially outward from the axis, the band formed with holes spaced along the band;
- a bolt located in the bolt housing, including teeth engaged with said holes for changing a diameter of the band as the band is tightened by rotating the bolt.
A tube clamping assembly, comprising:
- a fitting including a land extending circumferentially about a central axis and axially along the axis, the land having two portions separated by a circumferentially extending gap, a bolt housing integrally connected to both of the portions of the land, first and second legs integral with and extending from one of the two portions and spaced apart circumferentially along the land, a recess and a tooth in each of the legs, both portions of the land, the bolt housing, the first and second legs, the recesses, and the teeth being formed as a single monolithic piece;
- a band surrounding the axis, contacting both portions of the land radially outward from the axis, the band formed with holes spaced along the band;
- a bolt located in the bolt housing, including teeth engaged with said holes for changing a diameter of the band as the band is tightened by rotating the bolt.
A clamped connection, comprising:
- a fitting including a land extending circumferentially about a central axis and axially along the axis, the land haying two portions separated by a circumferentially extending gap, a bolt housing integrally connected to both of the portions of the land, a leg integral with and extending from one of the two portions, the leg including a recess and a tooth, both portions of the land, the bolt housing, the leg, the recess and the tooth being formed as a single monolithic piece;
- a tube including an end surface located in the recess, and a wall that is engaged by the tooth;
- a band extending circumferentially around the tube and formed with holes spaced along the band;
- a bolt located in the bolt housing including threads for engaging the holes, the band being clamped against the tube as the band is tightened by rotating the bolt.
