Abstract: A variable camshaft timing device adjusts phase between a camshaft and a crankshaft and includes a first ring gear configured to connect to the camshaft and rotate about a center axis, having a plurality of radially-inwardly facing gear teeth; a second ring gear axially spaced from the first ring gear, configured to receive rotational input from the crankshaft and rotate about the center axis, having a plurality of radially-inwardly facing gear teeth; a planetary gear assembly including one or more planet gears that are configured for rotation by an electric motor and engage the first ring gear and the second ring gear through the planet gear(s); and a cushioned stop configured to transmit energy between the planetary gear assembly and a planetary gear stop attached to a sprocket or a camshaft plate.

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 coupling assembly (20, 120, 220) and method can include a first rotatable member (22, 122, 222) and a second rotatable member (26, 126, 226) defining a cylindrical hub portion having a plurality of springs (42, 142, 242) interposed between the cylindrical hub portion of the second rotatable member (26, 126, 226) and the first rotatable member (22, 122, 222) for transferring rotational torque between the first and second rotatable members. A plurality of load-bearing surfaces (32, 132, 232) associated with the first rotatable member (22, 122, 222) are engageable by the plurality of springs (42, 142, 242) to accommodate radial clearances (34, 36, 134, 136, 234) between the first rotatable member (22, 122, 222) and the cylindrical hub portion while providing rotational drive torque from the first rotatable member (22, 122, 222) to the second rotatable member (22, 122, 222) through the plurality of springs (42, 142, 242).

Abstract: A system (42) including a phaser (28), a motor (38), and a controller (40) for controlling the phase between a camshaft (18) and a crankshaft (16) of an engine (10). The phaser (28) is attached to the camshaft (18), is in communication with the crankshaft (16), and is configured to adjust the phase of the camshaft (18). The motor (38) actuates the phaser (28) and is operatively attached to and in communication with the phaser (28) such that rotation of the crankshaft (16) back-drives the motor (38) to subsequently generate a signal. The controller (40) is in electrical communication with the motor (38), is responsive to the signal, and uses the signal to determine the rotational speed of the motor (38) to thereby commutate the motor (38) and subsequently drive the motor (38) so as to actuate the phaser (28) and control the phase of the camshaft (18).
