Abstract
Abstract A taper adapter sleeve for mounting an element with a bore, for example a roller bearing, on an axle journal or the like, characterized in that it comprises a portion, the inner and/or outer surface of which is provided about its circumference with axially directed grooves and ridges, and that the crests of said ridges define a circumscribed or inscribed cone or cylinder.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
140 words
An adapter sleeve for use as an adapter between the bore of a bearing and a shaft on which the bearing is mounted, the adapter sleeve comprising a substantially cylindrical wall with first and second ends, the wall being tapered along its length between said first end having first outer diameter and said second end having larger outer diameter, the sleeve wall including axially extending lands which are situated around the inner and outer circumferences and alternately project radially inward and outward respectively, said wall having substantially constant thickness throughout, said inward projecting lands defining a substantially constant diameter bore of first inner diameter, said sleeve further comprising an annular portion which extends co-axially from said first end and has screw threads on its outer surface, said lands and taper extending axially to the terminal part of said second end.
Claim 2
Dependent Claim
140 words
An adapter sleeve for use as an adapter between the bore of a bearing and a shaft on which the bearing is mounted, the adapter sleeve comprising a substantially cylindrical wall with first and second ends, the wall being tapered along its length between said first end having first outer diameter and said second end having larger outer diameter, the sleeve wall including axially extending lands which are situated around the inner and outer circumferences and alternately project radially inward and outward respectively, said wall having substantially constant thickness throughout, said inward projecting lands defining a substantially constant diameter bore of first inner diameter, said sleeve further comprising an annular portion which extends co-axially from said first end and has screw threads on its outer surface, said lands and taper extending axially to the terminal part of said second end.
Claim 3
Dependent Claim
145 words
An adapter sleeve for use as an adapter between the bore of a bearing and a shaft on which the bearing is mounted, the adapter sleeve comprising a substantially cylindrical wall with first and second ends, the wall being tapered along its length between said first end having first outer diameter and said second end having larger outer diameter, the sleeve wall including axially extending radially inward projecting lands which are uniformly spaced around the inner circumference and axially extending, radially-outward projecting lands each of which is opposite an inward projecting land such that said wall has thickness alternating between thick where there are lands and thin between said lands, said inward-projecting lands defining a substantially constant diameter bore of first inner diameter, said sleeve further comprising an annular portion which extends co-axially from said first end and has screw threads on its outer surface.
Claim 4
Dependent Claim
145 words
An adapter sleeve for use as an adapter between the bore of a bearing and a shaft on which the bearing is mounted, the adapter sleeve comprising a substantially cylindrical wall with first and second ends, the wall being tapered along its length between said first end having first outer diameter and said second end having larger outer diameter, the sleeve wall including axially extending radially inward projecting lands which are uniformly spaced around the inner circumference and axially extending, radially-outward projecting lands each of which is opposite an inward projecting land such that said wall has thickness alternating between thick where there are lands and thin between said lands, said inward-projecting lands defining a substantially constant diameter bore of first inner diameter, said sleeve further comprising an annular portion which extends co-axially from said first end and has screw threads on its outer surface.
