摘要： A method of setting lash in a cam phaser includes rotating a stator having a lobe in a first direction so that the lobe contacts a motion limiter pin disposed within a first hole in a rotor, causing the compression of a spring until a motion limiter lock pin enters a groove on the motion limiter pin and contacts a wall at one end of the groove. The rotor is then rotated in conjunction with the stator in the first direction until a rotor locking pin that is disposed within a second hole in the rotor engages a lock pin seat on a cover at one end of the seat. The rotor is then held in place while rotating the stator in a second direction so that there is a gap between the wall at one end of the groove and the motion limiter locking pin.

摘要： A motion limiter system for a cam phaser includes a retractable motion limiter pin that is selectively extendable from a rotor in a cam phaser to contact a lobe on a stator to provide a positive stop for the rotor prior to engagement of a locking pin. Alternatively, the cam phaser may include two pins that are selectively extendable from opposite openings in a hole in the rotor to engage seats that are slightly offset from one another.

摘要： A partial assembly process for a vane-type cam phaser. A pulley/sprocket is loaded onto a first camshaft-shaped fixture with a cam nose extending beyond the length of an actual cam nose such that a phaser rotor containing a locking bolt, when mounted onto the cam nose, is displaced axially from the pulley/sprocket by an amount sufficient to set the axial engagement of the bolt upon final assembly. A stator is loaded onto the pulley/sprocket and is rotated clockwise until it contacts the rotor, thereby removing all rotational and radial lash from the system. One or more axial holes are bored through the pulley/sprocket and stator and a locking pin such as a roll pin is inserted to permanently pin the stator to the pulley/sprocket. Finally, the partially-assembled phaser is removed from the cam-like fixture, the rotor is fully seated against the pulley/sprocket, the locking bolt is withdrawn from the pulley/sprocket, the rotor is rotated to an intermediate position, and the phaser cover is added to the assembly.
