Adjustable camshaft

An adjustable camshaft for an internal combustion engine, comprising:

• an inner shaft;
• an outer shaft disposed coaxially with the inner shaft with respect to a rotation axis, the outer shaft having an elongated hole extending circumferentially to the rotation axis;
• a first cam connected non-rotatably to the inner shaft via a pin extending through the elongated hole, wherein the pin is connected free from play to the first cam and passes free from play through the inner shaft;
• a second cam connected non-rotatably to the outer shaft;
• at least two bearing elements connected fixedly to the outer shaft, wherein the first cam is disposed between the at least two bearing elements;
• and
• a phase adjuster including a rotor and a stator, the rotor operably coupled to the inner shaft and the stator operably coupled to the outer shaft, wherein at least one of (i) the inner shaft is connected axially mobile to the rotor such that the inner shaft is mounted axially floating with respect to the rotor, and (ii) the outer shaft is connected axially mobile to the stator such that the outer shaft is mounted axially floating with respect to the stator;
• wherein the at least two bearing elements fix and mount the first cam in an axial direction on the outer shaft such that the first cam via the pin fixes the inner shaft in the axial direction relative to the outer shaft, and wherein the pin passes through the elongated hole in a play-free manner relative to the axial direction.
