Abstract:
The bi-directional rotation offset pivot thrust bearing includes a carrier and an array of longitudinal protrusions thereon that run through the center axis of the carrier. An array of pads are in slidable engagement with the longitudinal protrusions to permit the thrusts pads to move between first and second rotational positions. The thrust pads are automatically offset pivoted in a first direction when in a the first rotational position and automatically offset pivoted in a second direction when in the second rotational position. The thrust pads are offset pivoted in an approximate 60 percent to 40 percent ratio with the leading side of the thrust pad being 60 percent in both the first rotational position and the second rotational position. A retainer is also provided to maintain the thrust pads in slidable communication with the protrusions.
