Abstract
Abstract A divided hub for removably supporting annular elements has at least two coaxial hub parts threadedly connectable with one another. A pair of disc portions are each provided on one of the hub parts and define with one another a circumferential groove for receiving and retaining an inner marginal zone of an annular element. Means is provided for aligning the disc portions with one another in radial direction of the hub parts when the latter are threadedly connected with one another.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
A divided hub for removably supporting annular elements, comprising at least two coaxial hub parts provided with cooperating screw threads and being threadedly connected with each other; a pair of disc portions each provided on and integral with one of said hub parts, said disc portions defining with one another a circumferential groove adapted to receive and retain an inner marginal zone of an annular element; means for aligning said disc portions with one another in radial direction of said hub parts in response to threaded connection of said hub parts with each other; and at least one annular zone of reduced thickness provided in at least one said disc portions so that the latter is at least slightly resiliently deflectable in response to axially directed stresses acting upon said one disc portion upon relative axial displacement of said hub parts in a sense threading the same together.
Claim 2
Dependent Claim
148 words
A divided hub for removably supporting annular elements, comprising at least two coaxial hub parts provided with cooperating screw threads and being threadedly connected with each other; a pair of disc portions each provided on and integral with one of said hub parts, said disc portions defining with one another a circumferential groove adapted to receive and retain an inner marginal zone of an annular element; means for aligning said disc portions with one another in radial direction of said hub parts in response to threaded connection of said hub parts with each other; and at least one annular zone of reduced thickness provided in at least one said disc portions so that the latter is at least slightly resiliently deflectable in response to axially directed stresses acting upon said one disc portion upon relative axial displacement of said hub parts in a sense threading the same together.
Claim 3
Dependent Claim
40 words
A divided hub as defined in claim 1, said means comprising an annular centering rim provided on one of said disc portions, and a corresponding cavity in which said centering rim is received on the other of said disc portions.
Claim 4
Dependent Claim
38 words
A divided hub as defined in claim 1, said disc portions having respective annular faces extending from the periphery thereof and being inclined with reference to one another so that said groove is of substantially V-shaped cross-sectional configuration.
Claim 5
Dependent Claim
83 words
A divided hub as defined in claim 1, said hub parts each comprising a hub portion coaxial with the respective disc portion, one of said hub portions being conical and the other having a complementary recess into which said one hub portion is inserted and said one hub portion also being resiliently deformable in response to stresses developing upon relative axial displacement of said hub parts in a sense inserting said one hub portion deeper into said recess of the other hub portion.
Claim 6
Dependent Claim
32 words
A divided hub as defined in claim 4, wherein said one hub portion is provided with a plurality of slots extending radially therethrough and subdividing it into a plurality of resilient tongues.
