Beschreibung
Zusammenfassung:	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.
