    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 camshaft phaser, including: a stator to receive rotational torque from an engine and including a radially inwardly facing surface and a slot in the radially inwardly facing surface; a rotor to non-rotatably connect to a camshaft, to be connected to an electric motor and including a first radially outwardly extending protrusion; and a spring non-rotatably connected to the stator and including a first portion disposed in the slot. The electric motor is arranged to rotate the rotor with respect to the stator. In a first circumferential position of the rotor with respect to the stator: no portion of the spring is disposed in the indent; and a second portion of the spring extends radially inwardly past the radially inwardly facing surface. In a second circumferential position of the rotor with respect to the stator, the second portion of the spring is disposed in the indent.

    Abstract: A cam phaser (30, 130, 230) dynamically adjusts a rotational relationship of a camshaft (32) of an internal combustion engine with respect to an engine crankshaft operably connected with a phaser sprocket (42, 142, 242). The cam phaser (30, 130, 230) can include a planetary gear assembly having a ring gear (34, 134, 234) driven by the phaser sprocket (42, 142, 242), a planetary gear carrier (36, 136, 236) connected to the camshaft (32), a sun gear (38, 138, 238), and at least one rotatable planetary gear (40, 140, 240). The cam phaser (30, 130, 230) can include a sprocket housing (44, 144, 244) connected with the phaser sprocket (42, 142, 242) and operable for connection with the ring gear (34, 134, 234), a cover plate (46, 146, 246) secured to the carrier (36, 136, 236), and a adapter (48) connected between the sun gear (38, 138, 238) and an electric motor (47) for changing an angular position of the sun gear (38, 138, 238) and adjustably varying a cam phase position of the camshaft (32) relative to the crankshaft.

    Abstract: A planetary rotor includes: a planetary gear engaged with a driving rotor and a driven rotor on an eccentric side; and a single sequence type planetary bearing having an outer ring held by the planetary gear, an inner ring supported by a planetary carrier in the radial direction and receiving a restoring force from an elastic component, and a plurality of spherical rolling elements interposed between the outer ring and the inner ring. The outer ring is arranged to form a rolling contact part in contact with the spherical rolling element on the eccentric side, with a contact angle to a specific side in the axial direction. A thrust-bearing part where the driving rotor is supported by the driven rotor on the specific side and on the eccentric side is located closer to a rotation center line of the driven rotor than the rolling contact part is.

    Abstract: A camshaft phaser, including: an input component arranged to receive torque from an engine; an advance hub; an advance wedge plate radially disposed between the input component and the advance hub; and an actuation assembly including an advance pin arranged to be disposed in an advance channel for a camshaft and an actuator pin. For an advance mode: the actuator pin is arranged to radially displace the advance pin into non-rotatable connection with the advance hub; the advance hub is arranged to rotate, with respect to the input component, in a first circumferential direction; and the advance wedge plate is arranged to block rotation of the advance hub, with respect to the input component, in a second circumferential direction, opposite the first circumferential direction.
