摘要： A bearing assembly (80) for use in a gas turbine engine to rotatably mount a torque tube in an access hole extending through a fan duct. The torque tube connects a variable stator vane bell crank positioned inside the fan duct to an actuator positioned outside the fan duct. The bearing assembly (80)includes a bearing (60) having a spherical external engagement surface (62) and a housing (70) having a flange and an annular interior surface (72) having an inner edge (74) and an outer edge (76). The interior surface (72) is sized and shaped for rotatably receiving the spherical external engagement surface (62) of the bearing (60) so the spherical engagement surface (62) and the annular interior surface (72) make contact along an annular contact area (100) centered on a contact plane (102) lying between the inner and outer edges (76). The contact plane (102) is tilted with respect to the flange at an angle (104) greater than five degrees.

摘要： A trunnion support for a variable-position stator vane (12) in a turbomachine (10). The stator vane (12) includes an upper trunnion (28) and a lower trunnion (40) to allow the stator vane to be pivoted about a longitudinal axis. The lower trunnion (40) is supported in a bushing (44) that is carried in an opening (54) provided in an annular stator vane carrier ring (52), and the bushing (44) is longitudinally split and is installed in the carrier ring (52) while in a laterally compressed condition so that when installed in the carrier ring (52) the bushing (44) bears against the carrier ring opening (54) in which it is positioned. When the carrier ring material expands with rising temperature, the pre-stress in the bushing (44) will cause it to expand to maintain tight frictional engagement between the bushing (44) and the opening (54) and thereby prevent relative rotation between the bushing (44) and the carrier ring (52) to minimize wear of the carrier ring material.
