    摘要: A target wheel for a camshaft phaser stamped and drawn from sheet metal stock. The hub region of the target wheel may be drawn such that it extends through the phaser cover plate and seals directly against the face of the rotor, allowing a shorter cam bolt and resulting in reduction in mass and cost of the phaser. Alternatively, a separate hub is formed and then attached to a simplified stamped and drawn target wheel, or a target wheel hub is formed integrally with the rotor and extends through the cover plate to mate with a simplified stamped and drawn target wheel. Preferably, the hub is formed having a neck extending through a central opening in the target wheel, which neck is peened over during assembly to secure the wheel to the hub.

    摘要: A target wheel/rotor pre-assembly for a camshaft phaser. A phaser rotor includes a central bore. A target wheel axial extension having a plurality of barbs is entered into the bore to fix the target wheel to the rotor, both axially and rotationally, prior to assembly of the rotor into a phaser stator during manufacture of the phaser. Simple gauge blocks or a fixture can be used to index the target wheel to the rotor such that all such rotor/wheel subassemblies are substantially identical, to a high degree of precision. Alternatively, the axial extension may be formed without barbs, the extension inserted into the rotor bore, and then the extension immobilized as by stamping of the barbs, tack welding, or the like. For another example, the axial extension may be formed as a separate intermediate barbed retainer that engages both the rotor bore and the target wheel.

    摘要: A fast-acting rotor-locking mechanism for a vane-type camshaft phaser. A straight-sided locking pin is disposed in a bushing in the rotor and is urged into a sprocket well by a return spring. A pad disposed at the bottom of the well is a travel stop for the pin. When the pin is fully seated against the pad, the pad covers a portion of the end of the pin. The uncovered portion of the pin end, exposed to oil pressure for unlocking the pin when it is fully seated, is decreased over the prior art pin, permitting use of a lighter locking spring having a lower spring rate. Because of the lighter locking spring, the pin accelerates more rapidly and unlocks significantly faster than in a comparable prior art phaser.

    摘要: An improved releasable and reusable self-sealing plug for mechanically sealing a bore. A cylindrical body is formed on its outer surface to retain radial sealing means such as an O-ring. An oversize annular cap at the outer end of the body limits ingress of the plug into a bore, and a pair of opposed, flexible limbs terminating in flanges beyond the inner end of the body are compressed radially during insertion of the plug and spring out at completion of insertion to grip the inner entrance to the bore, thus holding the O-ring and plug in the bore. Insertion may be accomplished manually without the aid of tools. The plug cannot be driven out by pressure on the bore, but is easily removed by recompression of the limbs and flanges and withdrawal of the plug by, for example, needle-nose pliers. The plug may be formed inexpensively and easily by injection molding of a suitable plastic polymer.

    摘要: A steady bearing for the free end of a mixer shaft, which may be made from composite (fiber reinforced plastic) materials in substantial part, has a generally bell-shaped body with a neck in which the free end of the shaft or a shaft extension is disposed. A bearing assembly is removably disposed in the neck. The bearing has a bushing which is keyed to an inner sleeve around the shaft and to an outer sleeve by keyways which are open at one end so that the bushing and outer sleeve can be axially displaced for initial installation of the steady bearing and also when the bushing thereof requires replacement. When the shaft is too large to fit inside of the steady bearing. A reduced diameter shaft extension is provided to fit the steady bearing.

    摘要: A vane-type camshaft phaser includes a rotor having a plurality of vanes disposed in a stator having a plurality of lobes, the interspersion of vanes and lobes defining a plurality of alternating valve timing advance and valve timing retard chambers. Each vane and lobe tip is provided with an axially extending groove having an outward expansion of width. A wiper seal element, formed by stamping and folding from a single piece of sheet material, has folded wings that extend under compression into the groove. The spring loading of the wings against the tapered walls of the groove acts to urge the wiper seal element out of the groove and toward the opposing stator or rotor wall, thus ensuring a continuous forced sealing contact of the wiper seal element with the opposing wall and the groove walls during operation of the camshaft phaser.

    摘要: In a vane-type camshaft phaser, one vane extends over a much larger internal angle than the other two vanes. Because of its size and strength, the large vane is the vane designated for contact with the stator. The other vanes and lobes have extra clearance to prevent contact regardless of rotor position. In one embodiment, a first surface of the large vane engages a surface of a first adjacent lobe at one extreme rotor rotation, and a second surface of the large vane engages a surface of a second adjacent lobe at the opposite extreme of rotation. The contact surfaces of the lobes and the vane may be equipped with hardened wear pads. One or more wear pads may be machined to provide a desired rotor displacement angle.

    摘要: In a first embodiment of a camshaft phaser, the rotor is split along an equatorial plane thereof, defining first and second rotor portions. A resilient seal is compressively disposed between the rotor portions to prevent leakage therebetween and to urge the rotor vanes against the cover plate and sprocket surfaces to prevent leakage around the vanes. Preferably, the seal includes radial seal elements to seal against the stator wall. Preferably, pressurized hydraulic fluid can enter between the first and second rotor portions and thereby assist the resilient seal in urging the rotor portions apart. In a second embodiment, the rotor is not split, and a resilient seal is provided on at least one axial face of the rotor vanes to seal the rotor vanes against the cover plate and sprocket surfaces.
