Abstract: On example of a rotorcraft bearing system includes a bearing housing attached to an elastomeric bearing on a longitudinal axis, an end surface of the elastomeric bearing attached to an end surface of the bearing housing. The rotorcraft bearing system also includes a sliding contact bearing having an end surface. The rotorcraft bearing system also includes an intermediate sliding contact bearing material layer. Under load on the longitudinal axis, the end surface of the sliding contact bearing is configured to contact an opposing end surface of the bearing housing through the intermediate sliding contact bearing material layer to form a rotational slip joint.

Abstract translation: 旋翼航空器轴承系统的示例包括：轴承壳体，其在纵向轴线上附接到弹性体轴承，弹性体轴承的端面附接到轴承壳体的端面。 旋翼航空器轴承系统还包括具有端面的滑动接触轴承。 旋翼航空器轴承系统还包括中间滑动接触轴承材料层。 在纵轴上的负载下，滑动接触轴承的端面构造成通过中间滑动接触轴承材料层与轴承壳体的相对端面接触以形成旋转滑动接头。
