Abstract
In some examples, an aircraft wheel assembly includes an axle, a bearing assembly, and a hub defining a bearing bore. The bearing bore may be configured such that the dynamic radial and axial thrust bearing reactions between the axle and the hub results in a first reaction force FR applied to the hub, the first reaction force FR having a radial component, and a second reaction force FN applied to the hub, the second reaction force FN having both a radial and an axial component.
Claims14
A vehicle wheel assembly comprising:
- an axle;
- a bearing assembly comprising a bearing spacer defining a compound radius;
- and
- a hub configured to rotate relative to the axle and defining a bearing bore, wherein the bearing assembly is positioned between the axle and the hub, the bearing spacer being configured to engage with the hub within the bearing bore, and the bearing bore being configured such that an interface between the hub and the bearing spacer does not include a surface that is perpendicular to an axis of rotation of the axle, and wherein the bearing bore is configured such that a reaction between the axle and the hub results in a first reaction force FR applied to the hub, the first reaction force FR having a radial component, and a second reaction force FN applied to the hub, the second reaction force FN having both a radial and an axial component.
1 more element
A method comprising:
- forming a hub defining a bearing bore, wherein the bearing bore is configured such that when the hub is mounted on an axle of a vehicle via a bearing assembly, a reaction between the axle and the hub results in a first reaction force FR applied to the hub, the first reaction force FRhaving a radial component, and a second reaction force FN applied to the hub, the second reaction force FN having both a radial and an axial component, the bearing assembly comprising a bearing spacer defining a compound radius, the bearing spacer being configured to engage with the hub within the bearing bore, and the bearing bore being configured such that an interface between the hub and the bearing spacer does not include a surface that is perpendicular to an axis of rotation of the axle;
- and
- cold working the bearing bore.
