Abstract
A bearing arrangement is disclosed. The bearing arrangement includes first and second bearings, with each bearing including a respective support element and a respective set of rolling elements and defining a respective load path extending through the respective support element and rolling elements. The support elements are coupled such that a load applied to either support element is transmitted through both the first and second load paths. The arrangement further includes a pair of superelastic titanium alloy elements located in the respective load paths to provide resilient movement between the bearings when a load is applied to the bearing arrangement.
Claims16
A bearing arrangement comprising:
- a first bearing including a first support element and a first set of rolling elements, wherein a first load path extends through the first support element and the first set of rolling elements;
- a second bearing including a second support element and a second set of rolling elements, wherein a second load path extends through the second support element and the second set of rolling elements;
- a coupling between the first support element and the second support element arranged to transmit a load applied to either the first support element or the second support element through both the first and second load paths;
- and
- a superelastic titanium alloy element located in the first load path and the second load path.
