Abstract
Abstract A flexible coupling for two generally coaxially arranged shafts has a hub for each shaft, a flexible means disposed between and securely fixed to the hubs for tolerating axial misalignment between the shafts and a rigid means coaxially disposed between and loosely attached to the hubs for limiting axial movement of the hubs in respect of each other.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
A flexible coupling for two generally coaxially arranged shafts comprising: a. a hub for each of said shafts; each of said hubs including i. a shank portion, and ii. a flange portion of larger diameter than said shank portion; b. a flexible means for tolerating axial misalignment being coaxially disposed between said hubs and that is securely fixed to each flange of the respective hubs; said flexible means comprises a series of rectilinear resilient and compressible columns arranged with their longitudinal axes along the sides of a flat polygon; and arm extending transversely of said longitudinal axes at each intersection of two adjacent columns; alternate arms extending forwardly and rearwardly with respect to said flange and for decreasing the radius of said polygon whereby the columns are placed under a precompressive load; and c. a rigid means coaxially disposed between said hubs and being loosely attached to said shank portion of the respective hubs for limiting axial movement of said hubs in respect of each other.
Claim 2
Dependent Claim
166 words
A flexible coupling for two generally coaxially arranged shafts comprising: a. a hub for each of said shafts; each of said hubs including i. a shank portion, and ii. a flange portion of larger diameter than said shank portion; b. a flexible means for tolerating axial misalignment being coaxially disposed between said hubs and that is securely fixed to each flange of the respective hubs; said flexible means comprises a series of rectilinear resilient and compressible columns arranged with their longitudinal axes along the sides of a flat polygon; and arm extending transversely of said longitudinal axes at each intersection of two adjacent columns; alternate arms extending forwardly and rearwardly with respect to said flange and for decreasing the radius of said polygon whereby the columns are placed under a precompressive load; and c. a rigid means coaxially disposed between said hubs and being loosely attached to said shank portion of the respective hubs for limiting axial movement of said hubs in respect of each other.
Claim 3
Dependent Claim
60 words
The flexible coupling of claim 1 wherein said rigid means comprises a sleeve having a pair of axially spaced apart circumferentially arranged ribs projecting radially inwardly of said sleeve from the inside cylindrical surface of said sleeve; and, said shank portion of said hubs having an outer circumferential groove thereon for cooperation with a respective one of said cooperating ribs.
Claim 4
Dependent Claim
98 words
The flexible coupling of claim 1 wherein said rigid means comprises a sleeve having a pair of axially spaced apart circumferentially arranged grooves on the inside surface of said sleeve; each of said shank portions of said hubs having a matching circumferentially arranged outer groove thereon for cooperation with a respective one of said grooves of said sleeve; and, a retaining ring disposed in the space defined by both matching grooves of shank portion of said sleeve and of said hub; said retaining ring having a diameter less than the diameter defined by both of said coopErating grooves.
Claim 5
Dependent Claim
13 words
The coupling of claim 2 wherein said sleeve is constructed of two sections.
Claim 6
Dependent Claim
51 words
The coupling of claim 2 wherein each section has at least one threaded bore passing through common chords of both of said sections so that said bores in each section are matching; and, a cap screw extending through said bores of each section for holding said sections of said sleeve together.
