Abstract
Official abstract text for this publication.
A bearing assembly includes two tapered roller bearings having inner and outer rings and tapered rollers therebetween. The inner rings are mounted to a first machine part, and the outer rings are mounted on an adapter sleeve on a second machine part. The adapter sleeve has a first end axially fixed relative to the second machine part and a second end axially spaced from an axial stop of the second machine part by an axial gap. At a non-operating temperature, such as 20° C., the gap has a width of about 30 μm to 250 μm, and at an operating temperature of over 50° C. the gap disappears and the second end contacts the axial stop. The width of the gap at the non-operating temperature is selected to produce a predetermined preload on the bearing assembly at the operating temperature.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bearing assembly, comprising two tapered roller bearings, each including an inner ring, an outer ring, and tapered rollers disposed between the inner rings and the outer rings, wherein the inner rings are mounted in or on a first machine part and wherein the outer rings are mounted in or on a second machine part, wherein the inner rings or the outer rings include cylindrical counter-seats disposed on a cylindrical seat of an adapter sleeve supporting…
