    Abstract: An electric phaser for dynamically adjusting the phase of a camshaft relative to a crankshaft with a split ring planetary drive. The split ring planetary drive including: a sun gear driven by a motor, a plurality of planetary gears with stop teeth, a first ring gear driven by the crankshaft, and a second ring gear rotatable with the camshaft. Either the first or second ring gears each include a first and a second stop. When the stop teeth of the planetary gears interacts with the first stop or the second stop on either the first or second ring gears, rotation of the phaser further in the first direction or the second direction towards the first or second stops is halted.

    Abstract: An engine variable camshaft timing phaser (10) includes a sprocket (12) and a planetary gear set (14). The sprocket (12) receives rotational drive input from an engine crankshaft. The planetary gear set (14) includes two or more ring gears (34, 36), multiple planet gears (32), a sun gear (30), a first set of teeth (82), and a second set of teeth (40, 62). One of the ring gears (34, 36) can be connected to the sprocket (12) and one of the ring gears (34, 36) transmits rotational drive output to an engine camshaft. The sun gear (30) engages with the planet gears (32) and is driven by an electric motor (38). In order to bring the planetary gear set (14) to a locked condition, the first set of teeth (82) and the second set of teeth (40, 62) are mated with each other.

    Abstract: A valve timing controller includes a first housing; a second housing fixed to the first housing; a driven rotor inside of a driving rotor defined by the first housing and the second housing; a revolving actuator disposed on an extension of an axial direction of the driven rotor; a deceleration mechanism; and an engaging part that is engaged with a lock jig locking a relative rotation between the driving rotor and an input rotor of the deceleration mechanism in advance of assembling the valve timing controller to an internal-combustion engine. The engaging part is located on a radially inner side compared with an insertion part of the revolving actuator inserted in a hole of a cover component of the internal-combustion engine.

    Abstract: A valve timing controller includes a driving rotor, a driven rotor, a planetary rotor, a planetary carrier, and an elastic component to produce a restoring force biasing the planetary rotor to an eccentric side such that the driving rotor is inclined to the driven rotor. The driving rotor has an inclination angle θ1 relative to the driven rotor in a first inclination state where the driving rotor is in contact with the driven rotor on both sides in the axial direction. The inclination angle θ1 is smaller than an inclination angle θ2 in a second inclination state where the driving rotor is in contact with the driven rotor on both sides in the radial direction, and is smaller than an inclination angle θ3 in a third inclination state where the driving rotor is in contact with the camshaft on both sides in the radial direction.

    Abstract: A camshaft phase adjuster assembly is provided that includes at least one helical groove for adjusting a phase position between a camshaft and a drive sprocket. The camshaft phase adjuster assembly includes a camshaft including at least one helical groove extending between a bore and a radially outer surface of a sprocket support portion, and the helical groove includes circumferentially offset first and second ends. A drive sprocket includes at least one axially extending drive sprocket groove on a radially inner surface of the drive sprocket arranged facing the at least one helical groove. An actuator selectively moves an actuator pin axially such that a radially extending rotation pin slides within the helical groove and the drive sprocket groove from a first phase position to a second phase position.

    Abstract: A cam phaser (10) dynamically adjusts a rotational relationship of a camshaft (24) of an internal combustion engine with respect to an engine crankshaft (34). A cam sprocket (20) can be driven by an endless loop power transmission member connected to a drive sprocket (36) mounted for rotation with the engine 5 crankshaft (34). The cam phaser (10) can include a planetary gear drive train (12) having a centrally located sun gear (14) connected for rotation with the cam sprocket (20), a ring gear (18) connected for rotation with the camshaft (24), and a plurality of planet gears (16a, 16b) supported by a carrier (22) in meshing engagement between the sun gear (14) and the ring gear (18). A phase adjustment gear (26) can be 10 connected for rotation with the carrier (22). The sun gear (14) can drive the planet gears (16a, 16b) in rotation thereby causing the ring gear (18) to be driven in rotation. Rotational movement the phase adjustment gear (26) can adjustably vary a cam phase position of the camshaft (24) relative to the crankshaft (34).
