Abstract
A camshaft phaser has a stator configured to be non-rotatably connected to a drive sprocket and a rotor at least partially rotatable with respect to the stator and configured to be non-rotatably connected to a camshaft. The rotor has an aperture extending in a direction parallel to an axis of rotation. The camshaft phaser further has a support member including a bushing including an elongated portion, a flange, and a through-bore extending through the elongated portion and the flange, and a cylindrical pin disposed in the through-bore and the aperture. The camshaft phaser also has a positioning spring engaged with the support member and the stator to bias the rotor in a circumferential direction.
Claims14
A camshaft phaser positioned with respect to an axis of rotation, the camshaft phaser comprising:
- a stator configured to be non-rotatably connected to a drive wheel;
- a rotor at least partially rotatable with respect to the stator and configured to be non-rotatably connected to a camshaft, the rotor including an aperture extending in a direction parallel to the axis of rotation;
- a support member including:
- a bushing including an elongated portion, a flange, and a through-bore extending through the elongated portion and the flange;
- and
- a cylindrical pin disposed in the through-bore and the aperture;
- and
- a positioning spring engaged with the support member and the stator to bias the rotor in a circumferential direction.
A method of assembling a camshaft phaser, comprising:
- inserting a cylindrical pin into a through-bore of a bushing and an aperture formed in a rotor such that the bushing is secured to the rotor;
- and
- engaging a positioning spring with the bushing and a stator of the camshaft phaser, thereby biasing the rotor in a circumferential direction with respect to the stator,
- wherein the positioning spring is engaged with the bushing such that the positioning spring is retained radially and axially.
