System and method of monitoring wear in a bearing |
| 摘要 |
A bearing can include a ball member, a race, and a liner located on an interior surface of the race, the liner having a first surface bonded to an interior surface of the race, the liner having a second surface that is adjacent to the ball member. The bearing also includes a wafer having a wear surface that is aligned with the second surface of the liner, the wafer being an electrically conductive member. Operational wear of the liner can be calculated by comparing a measured resistance of the wafer to an original known resistance of the wafer. |

1. A bearing, comprising:
a ball member; a race; a liner located on an interior surface of the race, the liner having a first surface bonded to an interior surface of the race, the liner having a second surface that is adjacent to the ball member; and a wafer having a wear surface that is aligned with the second surface of the liner, the wafer being an electrically conductive member with an initial resistance; wherein a wear inducing operation causes the wafer to wear along with the liner, thus causing a decrease of the initial resistance such that an amount of the decrease of the initial resistance is indicative of an amount of wear of the liner. |
