Abstract
Abstract A rotary shaft coupling is composed of two identical sections. Each section consists of a dished annulus whose inner edge is flanged. Each section also includes a hub in the form of a split sleeve, one end of which has radially outwardly projecting tabs. The sleeve is received in the annulus so that the tabs engage the flanged inner edge of the annulus. When the sleeve is seated in this fashion, it is concentric with the annulus and properly positioned axially with respect thereto. The tabs are then brazed to the inner edge of the annulus. Two of these sections are positioned coaxially opposite one another and the outer annulus edges are continuously welded all around to complete the coupling.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
95 words
A rotary shaft coupling comprising a pair of dished annuli A. arranged concave toward one another, and B. secured together at their peripheries, each said annulus having 1. a central opening, 2. a sleeve positioned in the opening, said sleeve having a flare at one end thereof which seats in the opening and is brazed to the annulus portion around the opening, and 3. means for securing the flare to the wall of the opening, and C. further including clamps engaging around the sleeves for preventing rotation of the sleeves relative to shafts coupled thereto.
Claim 2
Dependent Claim
95 words
A rotary shaft coupling comprising a pair of dished annuli A. arranged concave toward one another, and B. secured together at their peripheries, each said annulus having 1. a central opening, 2. a sleeve positioned in the opening, said sleeve having a flare at one end thereof which seats in the opening and is brazed to the annulus portion around the opening, and 3. means for securing the flare to the wall of the opening, and C. further including clamps engaging around the sleeves for preventing rotation of the sleeves relative to shafts coupled thereto.

Claim 7
Dependent Claim
49 words
a sleeve positioned in the opening, said sleeve having a flare at one end thereof which seats in the opening and is brazed to the annulus portion around the opening, the inner edge of each annulus being flanged so that it overlaps the flared end of the sleeve, and
Claim 8
Dependent Claim

a sleeve positioned in the opening, said sleeve having a flare at one end thereof which seats in the opening and is brazed to the annulus portion around the opening, the inner edge of each annulus being flanged so that it overlaps the flared end of the sleeve, and
Claim 9
Dependent Claim
37 words
a split sleeve positioned in the opening, said sleeve having a flare at one end thereof which seats in the opening, said flare being formed by a plurality of tabs splaying out from the sleeve end, and
Claim 10
Dependent Claim
37 words
a split sleeve positioned in the opening, said sleeve having a flare at one end thereof which seats in the opening, said flare being formed by a plurality of tabs splaying out from the sleeve end, and
Claim 11
Dependent Claim
11 words
means for securing the flare to the wall of the opening.
Claim 12
Dependent Claim
11 words
means for securing the flare to the wall of the opening.
Claim 13
Dependent Claim
11 words
means for securing the flare to the wall of the opening.
Claim 14
Dependent Claim
11 words
means for securing the flare to the wall of the opening.
Claim 15
Dependent Claim
27 words
A rotary shaft coupling comprising a pair of dished annuli A. arranged concave toward one another, and B. secured together at their peripheries, each said annulus having
Claim 16
Dependent Claim
27 words
A rotary shaft coupling comprising a pair of dished annuli A. arranged concave toward one another, and B. secured together at their peripheries, each said annulus having
Claim 17
Dependent Claim
31 words
means for securing the flare to the wall of the opening, and C. further including clamps engaging around the sleeves for preventing rotation of the sleeves relative to shafts coupled thereto.
Claim 18
Dependent Claim
31 words
means for securing the flare to the wall of the opening, and C. further including clamps engaging around the sleeves for preventing rotation of the sleeves relative to shafts coupled thereto.
Claim 19
Dependent Claim
40 words
A rotary shaft coupling as defined in claim 3 and further including cutouts in each annulus, said cutouts being distributed around the axis of the annulus to increase the flexibility of the coupling without unduly hurting its torque transmission capability.
Claim 20
Dependent Claim
32 words
A rotary shaft coupling as defined in claim 4 wherein the cutouts in each annulus are A. disposed symmetrically about the axis thereof, and B. positioned near the periphery of the annulus.
