Abstract
A metal bellows coupling comprises a first hub, a second hub and a bellows, which is interposed between the first hub and the second hub; the bellows comprises a tubular body having a longitudinal axis and axially delimited by a first end and a second end; the bellows is made of a metal material and has an intermediate portion, which is interposed between the first end and the second end; the intermediate portion of the bellows has a plurality of folds; each end of the bellows has a mating surface, which is configured to come in contact, in use, with a respective hub; the mating surface is at least partially knurled, defining a first knurling.

A metal bellows coupling comprising a first hub, a second hub and a bellows, which is interposed between the first hub and the second hub;
- in which the bellows comprises a tubular body presenting a longitudinal axis bounded axially by a first end and a second end;
- the bellows is made of metallic material and has an intermediate portion that is interposed between the first end and the second end;
- wherein the intermediate portion of the bellows has a plurality of folds;
- wherein each end of said bellows has a first mating surface that is configured to come in contact, in use, with a respective hub;
- wherein said first mating surface is at least partially knurled, defining a first knurling.
A method for assembling a metal bellows coupling comprising a first hub, a second hub, and a bellows, which is interposed between the first hub and the second hub;
- wherein the bellows comprises a tubular body presenting a longitudinal axis bounded axially by a first end and a second end;
- wherein the bellows is made of a metallic material and has an intermediate portion which is interposed between the first end and the second end;
- wherein the intermediate portion of the bellows has a plurality of folds;
- wherein each end of said bellows has a first mating surface which is configured to come in contact, in use, with a respective hub;
- the method comprises the steps of:
- knurling at least part of the first mating surface;
- coupling the first end and the second end of the bellows to the respective hub along the longitudinal axis, so that the first mating surface comes in contact with the respective hub.
