Method for the compensation of tolerances between a stator and a rotor of a phase shifter for an adjustable camshaft

Abstract

A method may be used to adjust a gap between a stator and a rotor of a phase shifter for an adjustable camshaft. The stator may be connected to an outer shaft, and the rotor may be connected to an inner shaft of the adjustable camshaft. When the rotor rotates in the stator, a phase position of the inner shaft is adjusted relative to a phase position of the outer shaft. A gap may be formed between sliding surfaces on the stator and rotor. The method may involve coating at least one of the sliding surfaces with a removable coating, assembling the phase shifter including a joining of the rotor in the stator, starting up the phase shifter by rotating the rotor in the stator, and adjusting the gap between the stator and the rotor by way of abrasion of at least a partial thickness of the coating.
