Abstract:
A cam follower (10) for a ram of a metal can necker machine and a method of making the same. An outer ring (40, 70) has an outer ring bearing surface (42, 72) and an exterior surface (44, 74) defining a groove (46, 76) extending along at least a portion thereof. An inner ring (50, 80) is coaxially in the outer ring (40, 70) and has an inner ring bearing surface (52, 82). A plurality of rolling elements (54, 84) is disposed in an annular cavity (59, 89) between the outer ring bearing surface (42, 72) and the inner ring bearing surface (52, 82). The plurality of rolling elements (54, 84) are in rolling engagement with the outer ring bearing surface (42, 72) and the inner ring bearing surface (52, 82) so that the outer ring (40, 70) is rotatable relative to the inner ring (50, 80) about an axis of rotation (A). The outer ring (40, 70) is received in a tire (100). A least a portion of the tire (100) is disposed in the groove (46, 76) to inhibit axial movement of the tire (100) relative to the outer ring (40, 70).
Abstract:
A sealing system for a spherical plain bearing assembly is provided and includes a flexible seal defining a base and a head. At least one low-friction liner is disposed on the flexible seal.
Abstract:
An aircraft wing (12) includes a wing structure (12a), a slat panel (16) mounted on a track (18), and an actuator mechanism (26) on the wing structure coupled to the track for moving the slat panel between a deployed position and a retracted position. Track roller bearings (38) on the wing structure rotatably contact the track, and side roller bearings on the wing structure rotatably contact at least one side of the track. In another configuration, the actuator mechanism includes a shaft rotatably mounted on the wing structure, an actuator arm coupled to the track by a bearing linkage, and an actuator lever coupled to the shaft by a bearing linkage and to the actuator arm by a bearing linkage. At least one bearing linkage includes a spherical plain bearing.
Abstract:
A ground-based power generator that produces hot gas and that has a hot gas valving system includes a butterfly valve in a gas flow conduit. The generator is improved in that the butterfly valve is mounted in the conduit by a ball-roller bearing.
Abstract:
A spherical plain bearing has outer and inner rings each having a bearing surface, one bearing surface being in sliding disposition to the other. The inner ring has a third bearing surface for engaging a member to be mounted to the bearing. There is a lubrication groove in one or more of the first, second or third bearing surfaces, the lubrication groove comprising a contoured side. In an alternative a spherical plain bearing, there is a segmented lubrication groove in the third bearing surface that might have a sharp edge or a contoured side. A contoured lubrication groove can be formed by forming a lubrication groove that has a sharp edge; and machining the sharp edge to a contoured side having a reduced tendency to wipe lubricant from a second surface facing the lubrication groove.
Abstract:
A seal for a bearing includes a first annular retaining ring (72) defining a first radially outermost portion (72X) and a second annular retaining ring (74) defining a second radially outermost portion (74X). The seal includes a resilient ring (76) defining a third radially outermost portion (76X). The resilient ring is disposed between the first annular retaining ring and the second annular retaining ring. The first radially outermost portion, the second radially outermost portion and the third radially outermost portion are aligned with one another. The resilient ring projects radially inward from the first annular retaining ring and the second annular retaining ring. The resilient ring is more compressible and flexible than the first annular retaining ring and the second annular retaining ring.
Abstract:
An actuation system for deploying and retracting a lift assisting device of a leading edge of a wing of an aircraft including a track pivotally coupled to the lift assisting device. The track has first and second outer surfaces and side surfaces. The actuation system includes a shaft rotationally coupled within the wing of the aircraft and operable, in response to flight control signals, to deploy or retract the lift assisting device. The actuation system includes an actuator for actuating the lift assisting device, coupled to the shaft, between a retracted position to a deployed position along an arcuate path. The actuation system includes a plurality of track roller bearings rotatably contacting the first and second outer surfaces of the track to guide the track along the arcuate path. The plurality of track roller bearings includes one or more lined track roller assembly.
Abstract:
A spherical bearing has an outer ring with a concave bearing surface and an inner ring having a convex bearing surface, which is in sliding engagement with the concave bearing surface. A lubrication groove is formed in the convex bearing surface and/or the concave bearing surface. The lubrication groove is defined by a concave central portion and by convex side portions. The concave central portion has a first radius of curvature and the convex side portions have a second radius of curvature. The second radius of curvature is at least 0.7 times the first radius of curvature.
Abstract:
A spherical plain bearing (10) includes an inner ring (12) defining a convex outer surface (14) and an outer ring (16) defining a concave inner surface (18). The outer ring encircles the inner ring and one or more of the outer surface and the inner surface have a plurality of pockets (20) formed therein. A solid graphite plug (22) is disposed in one or more of the plurality of pockets and slidingly engages the outer surface and/or the inner surface.
Abstract:
An end cap (12) for a bearing assembly includes a first body portion (40) having a substantially annular sealing surface (42) positioned radially away from a central axis of the first body portion (40). The end cap includes a second body portion (46) extending from the first body portion, the second body portion (46) having at least one protrusion (51) extending radially therefrom.
