SUPPORT PIN FOR SPRING GUIDANCE IN A CAMSHAFT PHASER

摘要

A camshaft phaser including: a drive sprocket to receive torque; a stator non-rotatably connected to the sprocket; a rotor; and a positioning spring. The rotor is at least partially rotatable with respect to the stator and is arranged to non-rotatably connect to a camshaft. The rotor includes: first and second radially disposed sides facing, respectively, in first and second opposite axial directions parallel to the axis of rotation; a non-circular bore connecting the first and second radially disposed sides; a support pin including a first portion disposed in the bore and configured to contact an inner radial bore surface at a plurality of lines parallel to the axis of rotation less than the circumference of the bore; and a second portion extending past the second radially disposed side in the second axial direction. The positioning spring is engaged with the second portion and circumferentially urges the rotor.
