Abstract
A bearing assembly includes a stationary component, a rotatable component and a preloadable double row bearing unit having a rotatable bearing ring and a stationary bearing ring and two rows of rolling elements between the rings. The rotatable bearing ring and/or the stationary bearing ring includes a first part and a second part, and the first part is spaced from the second part by a gap so that the first part and the second part do not touch. At least one elastic element is disposed in the gap and fills the gap.
Claims3
A bearing assembly comprising:
- a stationary component,
- a rotatable component,
- a preloadable double row bearing unit, the bearing unit including a rotatable bearing ring and a stationary bearing ring, and
- a first row of a first plurality of rolling elements between the rotatable bearing ring and the stationary bearing ring and a second row of a second plurality of rolling elements between the rotatable bearing ring and the stationary bearing ring,
- a preloading means for preloading the preloadable double row bearing unit, wherein the preloadable double row bearing unit is preloaded by the preloading means,
- wherein the stationary bearing ring includes a first part and a second part,
- wherein the stationary bearing ring is connected to the stationary component and wherein the rotatable bearing ring is connected to the rotatable component such that they rotate together,
- wherein the first part is spaced from the second part by a gap so that the first part and the second part do not touch,
- wherein at least one elastic element formed from an elastomeric material is disposed in the gap and fills the gap, and
- wherein an axial width of a radial central portion of the elastic element is less than an axial width of a radial end portion of the elastic element.
