US 2010/0150487 A1 · Bearing assembly

Abstract

A bearing assembly comprises at least two axially-spaced bearings, each bearing including an inner ring. The at least two inner rings have differently-sized bore diameters. A sleeve-shaped connecting piece having a substantially frustum, conical or tapered shape is disposed between the two inner rings. An inner diameter of the connecting piece at its respective axial end regions corresponds to the respective bore diameter of the bordering inner ring so that first and second contact points are defined between the connecting piece and the respective inner rings. First and second curved or ring-shaped fixing elements are respectively disposed at the first and second contact points so as to fix the inner rings relative to the connecting piece in the radial direction of the bearing assembly. Each fixing element at least partially axially overlaps the connecting piece and the respective inner ring.

A bearing assembly comprising:

at least two axially-spaced bearings, each bearing comprising an inner ring, wherein the at least two inner rings have differently-sized bore diameters,
a sleeve-shaped connecting piece having a substantially frustum, conical or tapered shape disposed between and axially separating the two inner rings, wherein an inner diameter of the connecting piece at its respective axial end regions corresponds to the respective bore diameter of the adjacent inner ring so that first and second contact points are defined between the connecting piece and the respective inner rings, and
first and second curved fixing elements respectively extending adjacent the first and second contact points and fixing the respective inner rings relative to the connecting piece in a radial direction of the bearing assembly, each fixing element at least partially axially overlapping the connecting piece and the respective inner ring.

A bearing assembly comprising:

a first bearing comprising a first inner race having a first race bore diameter,
a second bearing comprising a second inner race having a second race bore diameter different from the first race bore diameter,
a hollow spacer disposed between the first and second inner races and at least substantially defining a spacing between the first and second inner races in an axial direction of the bearing assembly, the spacer having a first end adjacent to the first inner race and a second end adjacent to the second inner race, the first end having a first inner diameter at least substantially corresponding to the first race bore diameter and the second end having a second inner diameter at least substantially corresponding to the second race bore diameter, wherein a first junction is defined at a contact surface of the spacer and the first inner race and a second junction is defined at a contact surface of the spacer and the second inner race, and
at least one curved fastener disposed at least partially around and covering at least one of the first and second junctions, the fastener being configured to maintain at least one of the first and second inner races in position relative to the spacer in a radial direction of the bearing assembly.
