摘要： In a variable valve actuation apparatus with a speed reducer between a timing sprocket and a camshaft for changing a phase of the camshaft relative to the sprocket, while reducing normal-rotation/reverse-rotation of an electric motor, the speed reducer includes an eccentric rotation member connected to an output shaft of the motor, an annular member connected to the sprocket, a plurality of rollers installed between an inner toothed portion of the annular member and an outer peripheral surface of the eccentric rotation member, and a cage connected to the camshaft for circumferentially partitioning the respective rollers, while permitting a radial displacement of each roller. Depending on a dimension of a clearance space between the eccentric rotation member and the annular member, a suitable one of a plurality of roller sets, each having a different outside diameter, is selected, and then the selected rollers are installed.

摘要： A valve timing control apparatus for an internal combustion engine, including a drive rotation member, a follower rotation member, an electric motor, and a speed reducer including an internal gear portion, an eccentric cam on an inner peripheral side of the internal gear portion, rollers disposed between the internal gear portion and the eccentric cam, and a cage rotatable relative to the internal gear portion by rotation of the eccentric cam. A motor output shaft is arranged in series relative to the eccentric cam in an axial direction thereof. A needle bearing is rollably disposed on a part of an outer peripheral surface of the follower rotation member. The eccentric cam and the motor output shaft are press-fitted onto an outer peripheral portion of the needle bearing. The needle bearing extends over both the eccentric cam and the motor output shaft.
