Abstract:
An electrically-actuated variable camshaft timing (VCT) phaser assembly, comprises a sun gear configured to receive input from an electric motor and one or more planet gears having radially-outwardly-extending gear teeth that engage the sun gear; a first ring gear, having radially-inwardly extending gear teeth that engage the radially-outwardly-extending gear teeth of the sun gear, configured to receive rotational output provided by a crankshaft; a second ring gear, having radially-inwardly extending gear teeth that engage the radially-outwardly-extending gear teeth of the sun gear, configured to couple to a camshaft; one or more planet gear pins that carry the planet gear(s) and engage a planetary gear set to prevent the relative rotation of the planet gear pin(s) relative to the planetary gear set; and one or more springs that bias the planet gear pin(s) and the planetary gear(s) toward the first ring gear and the second ring gear.
