Abstract: An electrically-actuated variable camshaft timing (VCT) phaser is employed for use with an internal combustion engine (ICE). The electrically-actuated VCT phaser includes a gear set assembly and a fixture. The gear set assembly has an input gear and an output gear, among other possible components. The input gear receives rotational drive input from an engine crankshaft, and the output gear transmits rotational drive output to an engine camshaft. The fixture is secured in the gear set assembly. Amid installation of the electrically-actuated VCT phaser on the ICE, the fixture constrains rotational movement of the gear set assembly. After installation, the fixture can be removed from the gear set assembly.

Abstract: An electric phaser for dynamically adjusting a rotational relationship of a camshaft with respect to an engine crankshaft of an internal combustion engine includes an electric motor and a tapered roller drive. The tapered roller drive includes a sun, rollers, a carrier, at least one ring, and at least one load generator providing an axial load. The rollers are maintained in rolling engagement with the sun and the ring without the use of teeth. In some embodiments, the tapered roller drive is based on a fixed-sun design. In other embodiments, the tapered roller drive is based on a split ring design.

Abstract: A variable camshaft timing device that adjusts phase between a camshaft and a crankshaft includes a planetary gear assembly that changes an angular position of the camshaft relative to an angular position of the crankshaft; a sun gear configured to receive an output shaft of an electric motor that rotates at least a portion of the planetary gear assembly and controls phase adjustment between the camshaft and crankshaft by angularly displacing the camshaft with respect to the crankshaft; and a hydraulic lock (82) that releasably engages a portion of the variable camshaft timing device (10) in response to force applied by pressurized fluid thereby selectively preventing rotation of the camshaft relative to the crankshaft.

Abstract: An electrically-actuated variable camshaft timing (VCT) device, comprising: an input configured to receive rotational force from an electric motor; an output configured to couple with a camshaft of an internal combustion engine; a planet gear having radially outwardly extending gear teeth configured to engage ring gears and a radially-inwardly-facing surface; a planet pin, supporting the planet gear, having an outer surface and an axis of rotation about which the planet gear rotates; and a spring applying force in a substantially axial direction along the axis of rotation that moves the planet gear in a radial direction.

Abstract: A split ring planetary drive with at least one travel end stop received in at least one pocket of a first ring gear. The travel end stop is moveable between a first stop position in which as the planetary drive rotates in a direction the travel end stop engages the stop on the planet carrier, preventing further rotation of the split ring planetary drive in the direction, and a second position in which the travel end stop does not engage the stop on the planet carrier. The travel end stop may be a deadbolt, a snap ring or pivoting pawl.

Abstract: A phaser with a rotor assembly having a pattern on an inner diameter that acts as a sealing land or divider between the advance supply port and the retard supply port. This pattern allows the advance supply ports and the retard supply ports to be on the same plane, allowing the overall axial length of the rotor to be shorter. The pattern is preferably formed onto the inner diameter of the rotor through net forming.
