Abstract
Abstract A laminated diaphragm coupling for drive shafts having a plurality of identically corrugated annular laminas flexibly conformable to a common center of corrugation curvature. The laminas assemble in coaxial interlaminary supporting contact to provide a torsionally stiff and axially flexible laminated diaphragm. The diaphragms have inner and outer circumferential edge portions adapted for interconnection with each other and with coupling members.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
Laminated diaphragm coupling means comprising coaxial externally and internally serrated annular driving members interconnected by a plurality of coaxial externally and internally serrated annular laminas of thin, high strength, spring-tempered material, each of said laminas having an identically formed annular corrugation, said laminas being adapted for free coaxial assembly in partial interlaminary contact with each other and subsequent axial compression into full interlaminary contact with each other between annular compression retention means, the thinness and spring-tempered condition of said laminas enabling elastic re-forming of said identically formed corrugations to contiguous corrugations having a common center of corrugation curvature, said assembly thereby constituting a simply constructed laminated diaphragm of substantial axial thickness and high power transmitting capacity.
Claim 2
Dependent Claim
116 words
Laminated diaphragm coupling means comprising coaxial externally and internally serrated annular driving members interconnected by a plurality of coaxial externally and internally serrated annular laminas of thin, high strength, spring-tempered material, each of said laminas having an identically formed annular corrugation, said laminas being adapted for free coaxial assembly in partial interlaminary contact with each other and subsequent axial compression into full interlaminary contact with each other between annular compression retention means, the thinness and spring-tempered condition of said laminas enabling elastic re-forming of said identically formed corrugations to contiguous corrugations having a common center of corrugation curvature, said assembly thereby constituting a simply constructed laminated diaphragm of substantial axial thickness and high power transmitting capacity.
Claim 3
Dependent Claim
36 words
The coupling means as defined in claim 1 wherein said driving members are annularly grooved and said diaphragm assembles with inner and outer edge portions in axially compressed restraint between annular retaining members in said grooves.
Claim 4
Dependent Claim
42 words
The coupling means as defined in claim 2 wherein said outer edge portions are in axially spaced compressed restraint between outer edge annular retention means and said inner edge portions are in axially compressed abutting restraint between inner edge annular retention means.
Claim 5
Dependent Claim
26 words
The coupling means as defined in claim 1 wherein said laminas have a substantially conical form with inner and outer edge portions in axially spaced planes.
Claim 6
Dependent Claim
17 words
The coupling means as defined in claim 4 further comprising diaphragms having laminas of said conical form.
Claim 7
Dependent Claim
24 words
The coupling means as defined in claim 1 wherein said diaphragm further comprises a plurality of segmental lamina portions in coplanar circumferentially abutting relationship.
Claim 8
Dependent Claim
95 words
The coupling means as defined in claim 1 further comprising a plurality of said diaphragms having abutting inner edge portions interconnected by an externally serrated driving member, one of said diaphragms further having an externally serrated outer edge portion abutting an externally serrated outer edge portion of a driving member and having an internally serrated annular driving member bridging and interconnecting said abutting portions, and one of said diaphragms having an externally serrated outer edge portion engaging internal serrations of an annular driving member secured to a tubular member comprising a drive shaft extension thereof.
Claim 9
Dependent Claim
48 words
The coupling means as defined in claim 1 further comprising a plurality of diaphragms having abutting inner edge portions engaging an externally serrated drive shaft and having axially spaced outer edge portions bridged and interconnected by an internally serrated annular driving member to an externally serrated driving hub.
Claim 10
Dependent Claim
35 words
The coupling means as defined in claim 1 wherein said driving members further comprise annular diaphragm abutment and edge retention means arranged to absorb high axial compression, tensional and torsional loads transmitted through said diaphragms.
Claim 11
Dependent Claim
24 words
The coupling means as defined in claim 1 wherein the interconnection of said driving members and diaphragms includes manually removable diaphragm edge retention means.
