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.
摘要翻译：一种用于燃气涡轮发动机的轴承组件（80），用于将扭矩管可旋转地安装在延伸穿过风扇管道的进入孔中。扭矩管将位于风扇管道内部的可变定子叶片钟形曲柄连接到位于风扇导管外部的致动器。轴承组件（80）包括具有球形外部接合表面（62）的轴承（60）和具有凸缘的壳体（70）和具有内部边缘（74）和外部边缘（74）的环形内表面（72） 76）。内表面（72）的尺寸和形状适于可旋转地接收轴承（60）的球形外部接合表面（62），使得球形接合表面（62）和环形内表面（72）沿着环形接触区域（100）以位于内边缘和外边缘（76）之间的接触平面（102）为中心。接触平面（102）以大于5度的角度（104）相对于凸缘倾斜。
