Abstract
A camshaft phaser includes a housing having a housing bore extending along an axis and a plurality of lobes extending radially inward. The camshaft phaser also includes a stroke limiter having a central hub with a plurality of vanes extending radially outward such that the vanes are interspersed with lobes. The camshaft phaser also includes a harmonic gear drive unit disposed operationally between the housing and the stroke limiter, the harmonic gear drive unit being connected to a rotational actuator for imparting rotation on the harmonic gear drive unit such that rotation of the harmonic gear drive unit by the rotational actuator causes relative rotation between the housing and the stroke limiter. The amount of relative rotation between the housing and the stroke limiter is limited by at least one of the plurality of lobes and at least one of the plurality of vanes.
