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 radially within the circular spline and the dynamic spline, a wave generator disposed radially 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 radially within the housing and attachable to the camshaft and fixed to the other of the circular spline and the dynamic spline. A back plate has an array of external splines engaged in a sliding fit with the array of internal splines for transmitting torque from the back plate to said housing. The back plate also has an input sprocket for receiving rotational motion, in use.

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.

Abstract: A camshaft phaser controllably varies the phase relationship between a crankshaft and a camshaft in an internal combustion engine. The camshaft phaser includes an input member rotatable by the crankshaft. The input member is connected through a gear drive to an output member which is fixed to the camshaft. A rotational actuator acting on the gear drive unit causes relative roation between the input member and the output member. A first stop member is rotatable with the input member in a one-to-one relationship. A second stop member is rotatable with the output member in a one-to-one relationship to limit relative angular travel between the input member and the output member. A torque absorption means is provided for limiting the rate at which torque is applied from the rotational actuator to the gear drive unit when the second stop member makes contact with the first stop member.

Abstract: A camshaft phaser includes a housing with a harmonic gear drive unit disposed therein. The harmonic gear drive unit 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 coupling adapter is disposed coaxially within the housing bore and fixed to the wave generator and supported in the housing by a bearing which is press fit onto a bearing surface of the coupling adapter. The coupling adapter has a coupling adapter bore with opposing drive lugs extending radially inward therefrom which are axially coincident with the bearing surface. A coupling of the rotational actuator is disposed within the coupling adapter bore and has opposing drive slots which receive the opposing drive lugs, thereby transmitting motion from the coupling to the coupling adapter.
