Abstract
Abstract A device for mounting a bearing having an inner ring with a conical bore on a bearing seat having a conical clamping sleeve which, on the side of its large diameter, projects axially beyond the inner ring, comprising a spacer (12) positionable loosely on the end surface (13) of the inner ring (1) on the side of the clamping sleeve projection (A), the thickness of the spacer being less than that of the projection (A) in the preassembled state by an amount equal to the stroke (B) required to press in the clamping sleeve (9), the spacer thus limiting the distance (B) of the inward stroke.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
Device for mounting a bearing including an inner ring with a conical bore on a bearing seat, said device comprising a conical clamping sleeve having a larger diameter end projecting an axial distance (A) beyond the inner ring, and means for mounting the bearing to provide a different degree of pretension by a single clamping sleeve using spacers of different thicknesses, said spacer (12) loosely and non-threadedly mounted on the outer conical surface of the clamping sleeve, the thickness of said spacer being less than that of the axial projection (A) in the preassembled state by an amount equal to the stroke (B) required to press in the clamping sleeve (9), the spacer thus limiting the distance (B) of the inward stroke to achieve a predetermined radial tension and a nut member (16) for axially displacing the spacer and sleeve relative to one another said distance (B).
Claim 2
Dependent Claim
147 words
Device for mounting a bearing including an inner ring with a conical bore on a bearing seat, said device comprising a conical clamping sleeve having a larger diameter end projecting an axial distance (A) beyond the inner ring, and means for mounting the bearing to provide a different degree of pretension by a single clamping sleeve using spacers of different thicknesses, said spacer (12) loosely and non-threadedly mounted on the outer conical surface of the clamping sleeve, the thickness of said spacer being less than that of the axial projection (A) in the preassembled state by an amount equal to the stroke (B) required to press in the clamping sleeve (9), the spacer thus limiting the distance (B) of the inward stroke to achieve a predetermined radial tension and a nut member (16) for axially displacing the spacer and sleeve relative to one another said distance (B).
Claim 3
Dependent Claim
40 words
Device according to claim 1, wherein said spacer (12) has a predetermined thickness which takes into account the deviations from nominal dimensions of at least the inner ring (1) and the clamping sleeve (9) is assigned to each individual bearing.
Claim 4
Dependent Claim
15 words
Device according to claim 1, wherein the spacer (12) is designed as a spacer ring.
Claim 5
Dependent Claim
37 words
Device according to claim 1, wherein the projecting part of the clamping sleeve (9) is provided with an external thread (19) so that an extractor nut can be screwed on after the spacer (12) has been removed.
Claim 6
Dependent Claim
49 words
Device according to claim 1, including a component (16) which can be mounted in contact with the large end surface (14) of the clamping sleeve (9) and which secures the sleeve's axial position, said component having a surface (18) which rests against the end surface of the spacer (12).
