Abstract
Abstract The invention concerns expandable fastenings of the kind that includes a conical shaft part (2) and a conical expandable sleeve (4) that is pressed up on the conical part (2) of the shaft (1) in order to fill out and fasten the shaft in a mounting hole. The expandable sleeve (4) is pressed against the cone by a washer (5) and by a nut (11) screwed onto a threaded end portion of the shaft. The washer (5) is on its outside provided with a thread for the threading thereon of a nut part or sealing ring (6). The expandable sleeve (4) and the threaded washer (5) are connected by hooklike flanges so that the sealing ring (6) can also be used to pull out the sleeve from the conical axle part.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
132 words
An expandable device for attaching a shaft to a hub comprising: a shaft having a truncated conical end; an expandable sleeve having an inner conical surface mating with the truncated conical end and an exterior surface mating with a mounting hole in the hub; a threaded washer having a threaded outer surface and adapted to rotatably interconnect with one end of said expandable sleeve; a threaded part extending axially from said truncated conical end of said shaft and through said treaded washer; a nut mounted on said threaded part and threaded to engage said threaded washer, said nut having an outer diameter smaller than said outer surface of said threaded washer; and an internally threaded ring adapted to be threaded onto said outer surface of said threaded washer and engageing said hub.
Claim 2
Dependent Claim
132 words
An expandable device for attaching a shaft to a hub comprising: a shaft having a truncated conical end; an expandable sleeve having an inner conical surface mating with the truncated conical end and an exterior surface mating with a mounting hole in the hub; a threaded washer having a threaded outer surface and adapted to rotatably interconnect with one end of said expandable sleeve; a threaded part extending axially from said truncated conical end of said shaft and through said treaded washer; a nut mounted on said threaded part and threaded to engage said threaded washer, said nut having an outer diameter smaller than said outer surface of said threaded washer; and an internally threaded ring adapted to be threaded onto said outer surface of said threaded washer and engageing said hub.
Claim 3
Dependent Claim
35 words
Device according to claim 1, characterized in that the expandable sleeve and the threaded washer are connected by cooperating gripping surfaces allowing relative movement axially so that the expansion of the sleeve is not hindered.
Claim 4
Dependent Claim
22 words
Device according to claim 2, characterized in that the threaded washer and the expandable sleeve are freely rotatable relative to each other.
Claim 5
Dependent Claim
24 words
Device according to claim 2, characterized in that the threaded washer and the expandable sleeve are locked relative to each other against the rotation.
Claim 6
Dependent Claim
25 words
Device according to claim 2, characterized in that an outer diameter of the threaded washer is less than an inner diameter of the mounting hole.
Claim 7
Dependent Claim
22 words
Device according to claim 1, characterized in that the threaded washer and the expandable sleeve are freely rotatable relative to each other.
Claim 8
Dependent Claim
25 words
Device according to claim 6, characterized in that an outer diameter of the threaded washer is less than an inner diameter of the mounting hole.
Claim 9
Dependent Claim
23 words
Device according to claim 1 characterized in that the threaded washer and the expandable sleeve are locked relative to each other against rotation.
Claim 10
Dependent Claim
25 words
Device according to claim 8, characterized in that an outer diameter of the threaded washer is less than an inner diameter of the mounting hole.
Claim 11
Dependent Claim
27 words
An expanding device as in claim 9 wherein: the threaded outer periphery of said washer has a diameter less than that of the hole in the hub.
Claim 12
Dependent Claim
25 words
Device according to claim 1 characterized in that an outer diameter of the threaded washer is less than an inner diameter of the mounting hole.
Claim 13
Dependent Claim
155 words
An expandable device for attaching a shaft to a hub comprising: a shaft, said shaft having a truncated conical end; an expandable sleeve circumscribing the truncated conical end and having an internal inclined surface mating with the truncated conical end and an exterior surface mating with a hole in the hub; a washer having a threaded outer periphery and adapted to rotatably interconnect with one end of said expandable sleeve; a threaded part attached to said shaft and extending axially from the truncated conical end axially through said washer; a nut adapted to receive said threaded part and contact said washer, said nut having an outer diameter smaller than said outer periphery of said washer; and a sealing ring adapted to be threaded onto the outer periphery of said washer and engaging said hub, whereby said sealing ring prevents dirt and contamination from entering to the shaft and additionally facilitates disassembly of the expanding device.
