Abstract
A camshaft timing device includes a camshaft 10 and a drive gear 20 rotatably mounted thereon. An interconnecting shifting shaft 30 has spline 31 and 33 that interconnect with respective splines 16 and 41 on the camshaft and a hub of a drive gear 20. Axial movement of the shaft 30 causes the shaft to rotate the camshaft 30 with respect to the drive gear 20 due to the helical nature of the splines 33 and 41. The axial movement of the shaft 30 is caused by a drive sleeve 50 connected to a pinion gear that is driven through a worm gear 63 by an electric motor 67.
