| 发明名称 | Low offset hingeless rotor with pitch change bearings | ||
| 摘要 | A hub assembly for a tilt rotor includes a yoke having a plurality of yoke arms located substantially orthogonal to a central axis of the hub assembly. An inboard pitch change bearing assembly substantially surrounds a yoke arm of the plurality of yoke arms. An outboard pitch change bearing assembly is located at the yoke arm. The inboard pitch change bearing assembly and the outboard pitch change bearing assembly are operably connectable with a rotor blade to allow pitch change of the rotor blade relative to the yoke about a pitch change axis. | ||

| 主权项 | 1. A hub assembly for a tilt rotor comprising: a yoke having a plurality of yoke arms disposed substantially orthogonal to a central axis of the hub assembly; an inboard pitch change bearing assembly substantially surrounding a yoke arm of the plurality of yoke arms; an outboard pitch change bearing assembly located at the yoke arm, the inboard pitch change bearing assembly and the outboard pitch change bearing assembly operably connectable with a rotor blade to allow pitch change of the rotor blade relative to the yoke about a pitch change axis; and a spindle surrounding the yoke and secured thereto proximate to an axial through opening of the hub assembly. | ||
