Abstract
A bearing having an electrically conductive sleeve and a self-lubricating liner wherein the electrically conductive sleeve comprises a first portion and a second portion, the first portion and the second portion having respectively an inner surface and an outer surface; the self-lubricating liner extends over the inner surface of the first portion of the electrically conductive sleeve to define a first tubular volume, the first tubular volume having a first diameter and a first longitudinal axis; and the inner surface of the second portion of the electrically conductive sleeve defines a second tubular volume, the second tubular volume having the same diameter and the same longitudinal axis as the first tubular volume.
Claims8
A bearing comprising:
- an electrically conductive sleeve comprising a first portion and a second portion, the first portion and the second portion each having a respective inner surface and a respective outer surface;
- and
- a self-lubricating liner extending over the inner surface of the first portion of the electrically conductive sleeve to define a first tubular volume, the first tubular volume having a first diameter and a first longitudinal axis;
- wherein the inner surface of the second portion of the electrically conductive sleeve defines a second tubular volume that, when the bearing is in use, has the same diameter and the same longitudinal axis as the first tubular volume;
- and
- wherein the outer surface of the first portion of the electrically conductive sleeve radially extends further from the first longitudinal axis than the outer surface of the second portion of the electrically conductive sleeve.
A pin joint assembly comprising
- a bearing comprising:
- an electrically conductive sleeve comprising a first portion and a second portion, the first portion and the second portion each having a respective inner surface and a respective outer surface;
- and
- a self-lubricating liner extending over the inner surface of the first portion of the electrically conductive sleeve to define a first tubular volume, the first tubular volume having a first diameter and a first longitudinal axis;
- wherein the inner surface of the second portion of the electrically conductive sleeve defines a second tubular volume that, when the bearing is in use, has the same diameter and the same longitudinal axis as the first tubular volume;
- and
- wherein the outer surface of the first portion of the electrically conductive sleeve radially extends further from the first longitudinal axis than the outer surface of the second portion of the electrically conductive sleeve;
- a joint pin occupying the first and second tubular volumes;
- and
- a component in contact with the outer surface of the first portion of the electrically conductive sleeve such that the component is pivotally coupled to the joint pin.
