Abstract
A bearing assembly includes a hub element or housing element which has an accommodating bore for at least one rolling-element bearing, the rolling-element bearing being disposed with its outer ring in a press-fit arrangement in the accommodating bore, and the outer ring having at least one first axial region along at least one raceway of the outer ring and at least one second axial region extending outside the raceway. To ensure a proper fit of the bearing ring in the hub or housing element over a wide range of operating temperatures, the receiving bore and the outer circumference of the outer ring are configured such that at the ambient temperature the radial clamping force between accommodating bore and outer ring in the first region is smaller than in the second region.
Claims20
A bearing assembly comprising:
- a hub element or housing element having an accommodating bore, and
- at least one rolling-element bearing having an outer ring press-fit in the accommodating bore,
- wherein the outer ring has at least one first axial region, which extends along at least one raceway of the outer ring, and has at least one second axial region, which extends outside the at least one raceway of the outer ring, and
- the accommodating bore and the outer circumference of the outer ring are configured such that at ambient temperature (T0) a radial clamping force between the accommodating bore and the outer ring in the first axial region is smaller than a radial clamping force between the accommodating bore and the outer ring in the second axial region.
A bearing comprising:
- a hub element having an accommodating bore having a bore wall;
- and
- at least one rolling-element bearing mounted in the accommodating bore and having an outer ring, the outer ring having at least one raceway and an outer wall, a first axial region of the outer wall being axially aligned with the at least one raceway and a second axial region of the outer wall being not axially aligned with the at least one raceway;
- wherein the bore wall and the outer wall are configured such that a compression force between the bore wall and the outer wall in the first axial region is less than a compression force between the bore wall and the outer wall in the second axial region.
