Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
Resilient shaft coupling including a hub for connection to a first rotating part, a flange element for connection to a second rotating part, and a pair of resiliently acting annular elements for connecting the hub to the flange element, each annular element of the pair including a collar, a rim circumscribing the collar and a resilient annulus interconnecting the rim and the collar, and wherein the one axial end face of the hub and the flange element define axial clearance larger than the largest axial dimension of each of the elements of the pair, the improvement comprising in combination; a two-part spacer ring interposed between the rim of a first one of the annular elements of the pair and the flange element; means for releasably connecting the collars of the elements of the pair to the hub; and means for releasably connecting the rims of the pair to each other and to the flange element with interpositioning of the spacer ring between the first element of the pair and the flange element.
Claim 2
Dependent Claim
172 words
Resilient shaft coupling including a hub for connection to a first rotating part, a flange element for connection to a second rotating part, and a pair of resiliently acting annular elements for connecting the hub to the flange element, each annular element of the pair including a collar, a rim circumscribing the collar and a resilient annulus interconnecting the rim and the collar, and wherein the one axial end face of the hub and the flange element define axial clearance larger than the largest axial dimension of each of the elements of the pair, the improvement comprising in combination; a two-part spacer ring interposed between the rim of a first one of the annular elements of the pair and the flange element; means for releasably connecting the collars of the elements of the pair to the hub; and means for releasably connecting the rims of the pair to each other and to the flange element with interpositioning of the spacer ring between the first element of the pair and the flange element.
Claim 3
Dependent Claim
75 words
Coupling as in claim 1, wherein the axial length of each collar is larger than the axial length of the respective rim, the flange element being an annulus having inner diameter larger than the outer diameter of the collars, the axial length of the collars being slightly smaller than the distance from the said hub end face and a plane through the axial face of the flange element facing away from the hub end face.
Claim 4
Dependent Claim
50 words
Coupling as in claim 1, said rims, said spacer ring and said flange each having a plurality of axial, axially aligned bores, the bores in the flange being threaded, the means for connecting the rims including bolts traversing the bores and being threaded into the threaded bores of the flange.
Claim 5
Dependent Claim
23 words
Coupling as in claim 1, there being additional bores in the rims and additional bolts for bolting the two rims to each other.
Claim 6
Dependent Claim
31 words
Coupling as in claim 1 including two jaw coupler rings respectively connected to the rims and the collars for inhibiting rotation between the elements of the pair beyond a tolerance range.
Claim 7
Dependent Claim
15 words
Coupling as in claim 1, the two parts of the spacer ring being releasably interconnected.
