Abstract

A camshaft phaser includes a housing. 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. A wave generator bearing includes an inner race with an inner race axial end, an outer race, a plurality of balls between the inner and outer races, and a ball cage. The ball cage includes an annular section disposed axial from the balls proximal to the inner race axial end and a plurality of ball separators such that consecutive balls are separated by one of the ball separators. A rigid support ring extends axially beyond the inner race axial end toward the annular section to limit axial distortion of the annular section.
