Abstract
A rotor (1) for a vane cell adjuster of a camshaft adjusting device including a central through opening (10) and at least one radially outwardly projecting vane (2). The rotor (1) is made of at least two parts, an inner part (8) made of a first material and an outer part (3) made of a second material and which surrounds, from the outside, the inner part (8). The first material has a higher strength than the second material, and the inner part (8) is connected in a positive fit in the rotational direction of the outer part (3) by an outer form which is irregular in the cross-section to the rotational axis (14) of the rotor (1).
Claims10
A rotor for a vane cell adjuster of a camshaft adjusting device, the rotor comprising:
- an inner part made from a first material,
- an outer part made from a second material,
- a central passage opening in the inner part, the inner part having at least one opening arranged radially outside of the central passage opening and adapted to hold a locking pin of a locking device,
- at least one vane projecting radially outward on the outer part,
- the outer part surrounding an entire radial outer surface of the inner part,
- the first material has a higher strength than the second material, and
- the inner part is connected by a positive fit to the outer part in a rotational direction by an exterior shape that is non-circular in cross-section relative to a rotational axis of the rotor.
