摘要： A raceway surface (3a) of an outer ring (3) of a tapered roller bearing (1) includes a composite crowning surface. The composite crowning surface includes a center curve (3a1), which is formed at a center portion in a generating-line direction, and end portion curves (3a2 and 3a3), which are formed on both sides of the center curve (3a1) in the generating-line direction. The raceway surface (3a) of the outer ring (3) is entirely subjected to superfinishing. Each of a ratio (R2/R1) of a curvature radius (R2) of the end portion curve (3a2) to a curvature radius (R1) of the center curve (3a1) and a ratio (R3/R1) of a curvature radius (R3) of the end portion curve (3a3) to the curvature radius (R1) is set to 0.02 or more. Each of drop amounts of the end portion curves (3a2 and 3a3) is set to 0.07 mm or less.

摘要： An edge flap arrangement for an aircraft wing includes a main flap element and an actuator for moving the main flap element relative to the aircraft wing. A linkage arrangement supports the main flap element and includes a drop hinge link arrangement having a fixed strut secured to the aircraft wing and a drop link secured to the main flap element. The fixed strut and the drop link are connected by a hinge point having an hourglass bearing assembly having hourglass shaped rollers with a circular cross section symmetrical about a longitudinal axis, first and second axial ends, and an exterior surface. The exterior surface defines a concave engagement surface having a first radius of curvature R1 and a second radius of curvature which is greater than the first radius of curvature R1. The first radius of curvature is between 50 and 95 percent of the second radius of curvature.

摘要： The present invention provides a tapered roller bearing for an automobile transmission that is capable of preventing early surface originating flaking attributable to lack of oil film even when the oil film parameter Λ is in the range of 0.8 or less. Further, in a tapered roller bearing for an automobile transmission to be used with an oil film parameter Λ being equal to or more than 0.5, the roughness of the raceway surfaces of both the inner and outer rings is rendered less than twice the roughness of the rolling contact surface of a roller.
