Abstract
A camshaft phaser includes a housing with an array of internal splines formed within a bore. A harmonic gear drive unit is disposed within the housing and includes a circular spline and a dynamic spline, a flexspline disposed within the circular spline and the dynamic spline, a wave generator disposed within the flexspline, and a rotational actuator connectable to the wave generator. One of the circular spline and the dynamic spline is fixed to the housing. A hub is rotatably disposed within the housing and attachable to the camshaft and fixed to the other of the circular spline and the dynamic spline. An oil passage is provided for receiving oil from an internal combustion engine for lubricating the harmonic gear drive unit.
