Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16D 2504

US Classification:

192 88B

Abstract:

A coupling assembly component includes an annular base. A first annular friction surface is connected with the base and is movable into engagement with a second annular friction surface. An annular fluid extensible tube is inflatable to move the first friction surface into engagement with the second friction surface. A fitting is connected with the base and the tube to conduct fluid pressure into a chamber in the tube. An annular mounting ring is disposed in a coaxial relationship with the base and the tube. The annular mounting ring is embedded in the tube and is connected with a portion of the fitting. The annular mounting ring may be provided with only a single opening which is connected with a fitting through which fluid is conducted into the tube. However, the annular mounting ring may be provided with a plurality of openings connected with a plurality of fittings.

Abstract:

A coupling assembly includes an annular base which is connected with the first annular friction surface. An annular fluid extensible tube is disposed between the annular base and the first annular friction surface. A fitting is connected with the base and tube to conduct fluid pressure into a chamber in the tube. The fluid pressure extends the tube to press the first friction surface against the second friction surface. The fitting has a main section with a passage through which fluid pressure is conducted into the tube and a flange section which extends radially outward from the main section and is enclosed by material of the tube to retain the fitting in the tube. The main section and flange section of the fitting are integrally formed by a single piece of polymeric material. A plurality of openings are formed in the flange section and are filled with the material of the tube to interconnect the tube and the fitting.
