Abstract
Abstract A pair of double-conically shaped elements can be tightened against each other by means of clamping screws, the conical surfaces sliding over matching conical surfaces formed at opposed faces of inner and outer sleeves, adapted to seat respectively on a shaft, and in a hub. To form one self-retaining assembly, the inner ends of the conical elements are formed with projecting shoulders, for example by placing snaprings thereover, which engage in grooves in the inner and outer sleeves, so that the various parts of the connection will always remain together.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
Connection according to claim 1, wherein the interengaging shoulder and recess means comprise substantially cylindrical grooves (1b, 2b) formed in the inner and outer surfaces of the respective central region of the outer and inner sleeves (1, 2), respectively, inwardly directed radially extending projection means (4) formed on the inner end of the locking rings engaging in the outer groove (1b) of the inner sleeve (1) and outwardly directed radially extending projection means (5) formed on the outer end of the locking rings engaging into the inner groove (2b) of the outer sleeve (2).
Claim 2
Dependent Claim
15 words
Connection according to claim 2, wherein the inner projection means (4) comprises a circumferential ring.
Claim 3
Dependent Claim
15 words
Connection according to claim 2, wherein the outer projection means (5) comprises a circumferential ring.
Claim 4
Dependent Claim
19 words
Connection according to claim 2, wherein the inner projection means (4) comprises an axially split circumferentially extending spring ring.
Claim 5
Dependent Claim
19 words
Connection according to claim 2, wherein the outer projection means (5) comprises an axially split circumferentially extending spring ring.
Claim 6
Dependent Claim
28 words
Connection according to claim 2, wherein the inner projection means (4) comprises an essentially circumferentially extending shoulder formed at the inner end of the respective conical locking ring.
Claim 7
Dependent Claim
28 words
Connection according to claim 2, wherein the outer projection means (5) comprises an essentially circumferentially extending shoulder formed at the inner end of the respective conical locking ring.
Claim 8
Dependent Claim
85 words
Connection according to claim 1, wherein the clamp means comprises one of the locking rings (3) being formed with smooth bores, the other of the locking rings (3a) being formed with tapped bores, and bolts (6) passing through the smooth bores into the tapped bores, said one ring (3) being further formed with tapped bores (3c) extending towards the inner face of the other ring (3a) to permit threading of bolts into the further tapped bores (3c) and separate the lcoking rings by axial pressure.
Claim 9
Dependent Claim
97 words
Connection according to claim 1, wherein said double-conical locking rings (3, 3a) have inner cylindrical projections formed with grooves therein; and the interengaging shoulder and recess means comprise grooves (1b, 2b) circumferentially extending and formed in the respective central region of the inner and outer sleeves (1, 2), respectively, of sufficient width to span the distance between the axial extensions of the locking rings when loosely inserted in the assembly; and snap rings (4, 5) engaged in the grooves in the extensions and bearing against the shoulders formed in the sleeves by the grooves (1b, 2b) therein.
