A camshaft phaser (12) includes a camshaft phaser input member (18) connectable to a crankshaft; a camshaft phaser output member (20) connectable to a camshaft (14); an intermediate member (28) rotatable relative to the camshaft phaser input member (18) such that rotation of the intermediate member (28) relative to the camshaft phaser input member (18) causes the camshaft phaser output member (20) to rotate relative to the camshaft phaser input member (18); and a rotational actuator (100) configured to selectively rotate the intermediate member (28) relative to the camshaft phaser input member (18), the rotational actuator (100) comprising. The rotational actuator (100) includes a compound planetary gear set (118) having an input planetary gear set (124) driven by the camshaft phaser input member (18) and an output planetary gear set (126) driven by the input planetary gear set (124); and an adjusting actuator (120) connected to the compound planetary gear set (118). |
