Bearing assembly
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.
1 . 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.
2 . The bearing assembly according to claim 1 ,
wherein the gap is located between an axially inner end of the first part and an axially inner end of the second part,
wherein a first beveled surface extends from the axially inner end of the first part and a second beveled surface extends from the axially inner end of the second part, and
wherein the elastic element contacts the axially inner end of the first part, the first beveled surface, the axially inner end of the second part and the second beveled surface.
3 . 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,
wherein the gap is located between an axially inner end of the first part and an axially inner end of the second part,
wherein a first beveled surface extends from the axially inner end of the first part and a second beveled surface extends from the axially inner end of the second part, and
wherein a radially outer portion of the elastic element is located axially between the first beveled surface and the second beveled surface.
