Abstract
Abstract A frustro-conical holding ring is adapted to seat on a shaft; a closed outer holding ring having an internal frustro-conical surface seats and surrounds the first holding ring. To center these rings on the shaft and within the hub, cylindrical centering rings adapted to seat against the inner surface of the hub and on the shaft are formed adjacent the thicker ends of each of said rings, the cylindrical centering rings extending over a radial distance greater than the thickness of the thickened end to overlap the thinner end of the other ring, and center the holding rings on the shaft and within the hub. Disks of elastic material, such as rubber or plastic disks may be located between the end faces of a holding ring and the inner end face of the centering ring adapted to fit thereagainst to form an elastic and sealing insert. The entire arrangement can be tightened by relative axial shifting of the two holding rings against each other, for example by circumferentially arranged holding screws, a central screw with an interposed disk spring or the like. The center rings may be radially slitted, the radial slits extending into the holding rings.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
204 words
A hub-to-shaft connection having a frustro-conical inner holding ring (1) adapted to seat on the shaft (7), and a closed outer holding ring (2) having a frustro-conical inner surface matching the outer surface of said frusto-conical inner ring (1), said connection comprising a cylindrical centering ring (1a) adapted to seat against a surface of the hub formed on the thicker end of said inner holding ring and extending over a radial distance greater than the thickness of said thicker end and overlapping the thinner end of the outer holding ring; and a cylindrical centering ring (2a) adapted to seat against the inner surface of the hub and formed at the thicker end of said outer holding ring and extending over a radial distance greater than the thickness of said thicker end and overlapping the thinner end of the inner holding ring (1), said centering rings being provided to center a respective inner, or outer holding ring on the shaft, and within the hub (8), the outer diameter of the centering ring (1a) formed on the thicker end of the inner holding ring (1) having a diameter which is greater than the diameter of the centering ring (2a) formed on the outer holding ring (2).
Claim 2
Dependent Claim
204 words
A hub-to-shaft connection having a frustro-conical inner holding ring (1) adapted to seat on the shaft (7), and a closed outer holding ring (2) having a frustro-conical inner surface matching the outer surface of said frusto-conical inner ring (1), said connection comprising a cylindrical centering ring (1a) adapted to seat against a surface of the hub formed on the thicker end of said inner holding ring and extending over a radial distance greater than the thickness of said thicker end and overlapping the thinner end of the outer holding ring; and a cylindrical centering ring (2a) adapted to seat against the inner surface of the hub and formed at the thicker end of said outer holding ring and extending over a radial distance greater than the thickness of said thicker end and overlapping the thinner end of the inner holding ring (1), said centering rings being provided to center a respective inner, or outer holding ring on the shaft, and within the hub (8), the outer diameter of the centering ring (1a) formed on the thicker end of the inner holding ring (1) having a diameter which is greater than the diameter of the centering ring (2a) formed on the outer holding ring (2).
Claim 3
Dependent Claim
33 words
Connection according to claim 1 wherein at least one of the centering rings has radially extending slits (1b, 2b) formed thereon starting from an end face of the respective one of said rings.
Claim 4
Dependent Claim
51 words
Connection according to claim 2 wherein the radially extending slits formed in the centering rings continue into the holding ring on which the Centering ring is formed, said slits formed in the holding rings extending for a distance up to about one half of the axial length of the holding rings.
Claim 5
Dependent Claim
42 words
Connection according to claim 1 including disks of elastic material (5, 5a), located between at least one end face of a holding ring (1) and the inner end face of an opposed centering ring (2a) formed on the other holding ring (2).
Claim 6
Dependent Claim
48 words
Connection according to claim 1 including a disk spring (3) having a plane bearing surface, and means (6) securing said disk spring on the shaft and pressing said disk spring against one of said centering rings formed on one of said holding rings with said plane bearing surface.
