A flexure pivot tilting pad (80, 180) (FPTP) journal bearing (30, 32, 132) is used to support a rotating assembly of a turbocharger (10). The FPTP journal bearing (30, 32, 132) includes a cylindrical outer ring (60, 160) and flexure pivot tilting pads (80, 180) disposed within the outer ring (60, 160). The flexure pivot tilting pads (80, 180) are formed separately from the outer ring (60, 160) and secured thereto during assembly. |

1. A journal bearing (30, 32, 132) comprising
a cylindrical outer ring (60, 160) that includes
a first end (61),a second end (62),a longitudinal axis (63) that extends through the first end (61) and the second end (62),a radially outward-facing bearing surface (66), andan inner surface (68) opposed to the radially outward-facing bearing surface (66), the inner surface (68) including an axially extending groove (72, 172), and a flexure pivot tilting pad (80, 180) that includes
a bearing member (81) that is elongated in a circumferential direction and provides a radially inward facing bearing surface (82),an anchor portion (90, 190), anda web (88) that connects the bearing member (81) to the anchor portion (90, 190), wherein the anchor portion (90, 190) is disposed in the groove (72, 172) in such a way that the flexure pivot tilting pad (80, 180) is secured to the outer ring (60, 160), and the bearing member (81) is pivotable about the web (88) relative to the inner surface (68) of the outer ring (60, 160). |
