Hose clamp with positioning features
A hose clamp system is disclosed. The system includes a hose clamp and a retainer configured to attach the clamp to a hose substrate such that a desired radial, axial and circumferential position relative to the substrate outer diameter and hose end is maintained. The hose clamp includes an annular band including a radial inner surface facing toward a central axis and a radial outer surface positioned opposite the radial inner surface and a tension mechanism configured to tighten the annular band. The retainer includes an elongated body extending over the radial outer surface and a clip extending outward from the annular band that is configured to engage a hose substrate. The retainer is moveably coupled to the annular band such that the retainer is permitted to move circumferentially along the radial outer surface of the annular band.
1. A hose clamp system comprising:
an annular band including a radial inner surface facing toward a central axis and a radial outer surface positioned opposite the radial inner surface,
a liner positioned radially inward from the annular band, the liner defining an inner diameter,
a tensioner configured to tighten the annular band and reduce the inner diameter of the liner, and
a retainer including an elongated body extending over the radial outer surface of the annular band and a clip extending outward from the annular band, the clip being configured to engage a hose substrate,
wherein the retainer is moveably coupled to the annular band such that the retainer is permitted to move circumferentially along the radial outer surface of the annular band.
2. The hose clamp system of claim 1 , wherein the elongated body extends parallel to the central axis of the annular band.
3. The hose clamp system of claim 1 , wherein:
the annular band has an elongated slot extending through the radial outer surface, and
the retainer includes an alignment key that is received in the slot and is configured to move along the slot when the retainer is moved circumferentially along the radial outer surface of the annular band.
4. The hose clamp system of claim 3 , further comprising an eyelet configured to retain the alignment key in the elongated slot.
5. The hose clamp system of claim 4 , wherein the annular band includes a groove defined in the radial inner surface, the groove being sized to receive an inner flange of the eyelet.
6. The hose clamp system of claim 3 , wherein the annular band includes a detent sized to retain the alignment key at an end of the elongated slot.
7. The hose clamp system of claim 6 , wherein the detent extends outwardly from the radial outer surface.
8. The hose clamp system of claim 6 , wherein the alignment key is positioned between a channel defined in the retainer to permit the retainer to bend during installation.
9. The hose clamp system of claim 1 , further comprising a ramp block positioned between an end of the annular band and the retainer, the ramp block being sized to prevent an opposite end of the annular band from engaging the retainer.
10. A hose clamp system comprising:
an annular band including a radial inner surface facing toward a central axis and a radial outer surface positioned opposite the radial inner surface,
a tensioner configured to tighten the annular band, and
a retainer including an elongated body extending over the radial outer surface of the annular band and a clip extending outward from the annular band, the clip being configured to engage a hose substrate,
wherein the retainer is moveably coupled to the annular band such that the retainer is permitted to move circumferentially along the radial outer surface of the annular band.
11. The hose clamp system of claim 10 , wherein the elongated body extends parallel to the central axis of the annular band.
12. The hose clamp system of claim 10 , wherein:
the annular band has an elongated slot extending through the radial outer surface, and
the retainer includes an alignment key that is received in the slot and is configured to move along the slot when the retainer is moved circumferentially along the radial outer surface of the annular band.
13. The hose clamp system of claim 12 , further comprising an eyelet configured to retain the alignment key in the elongated slot.
14. The hose clamp system of claim 13 , wherein the annular band includes a groove defined in the radial inner surface, the groove being sized to receive an inner flange of the eyelet.
15. The hose clamp system of claim 12 , wherein the annular band includes a detent sized to retain the alignment key at an end of the elongated slot.
16. The hose clamp system of claim 15 , wherein the detent extends outwardly from the radial outer surface.
17. The hose clamp system of claim 15 , wherein the alignment key is positioned between a channel defined in the retainer to permit the retainer to bend during installation.
18. The hose clamp system of claim 10 , further comprising a ramp block positioned between an end of the annular band and the retainer, the ramp block being sized to prevent an opposite end of the annular band from engaging the retainer.
19. A hose clamp system comprising:
an annular band including a radial inner surface facing toward a central axis and a radial outer surface positioned opposite the radial inner surface,
a tensioner configured to tighten the annular band, and
a retainer including (i) a liner positioned along the radial inner surface of the annular band and (ii) a fastener coupling the liner to the annular band,
wherein relative circumferential movement between the annular band and the retainer is permitted.
20. The hose clamp system of claim 19 , wherein:
the annular band has an elongated slot extending through the radial outer surface, and
the fastener extends through the slot and is configured to move along the slot when the retainer is moved relative to the annular band.
