Abstract
A planetary gear assembly () and method of assembly in an electric camshaft phaser () with a split ring gear including a drive-side ring gear portion () rotatable by an engine crankshaft and an output-side ring gear portion () that can be connected to a camshaft (). A plurality of rotatable planetary gears () can be interposed between the split ring gear and the sun gear (). The output-side ring gear portion () can have a different number of teeth than the drive-side ring gear portion () by a value corresponding to a multiple of the number of planetary gears (). A compliant planetary gear carrier () can support the plurality of planetary gears () allowing variance of a normally equidistant distance between separate spaced rotational axes of at least two of the planetary gears () to selectively compensate for mechanical tolerances of the drive-side ring gear portion () and the output-side ring gear portion () of the split ring gear.
