Rotor comprising a two-part bearing seat

1 . An assembly for a rotor of an electrically excited electric machine comprising:

a rotor shaft which is fixedly connectable to a rotor core of the rotor to thereby conjointly rotate;

a slip ring module having at least one slip ring configured to energize rotor windings of the rotor; and

two bearing points arranged at axial ends of the rotor shaft with one annular bearing seat of one bearing of the rotor, wherein

one of the bearing points is of two-part configuration, a first part bearing point having a first part bearing seat and is configured in one part with the rotor shaft, and a second part bearing point having a second part bearing seat and being configured in one part with the slip ring module, the two part bearing points with the part bearing seats being connected in a positively locking and non-positive manner with configuration of the bearing point with the annular bearing seat,

the two-part bearing points engage into one another in a claw-like manner in order to provide the positively locking connection, and

the first part bearing point has two circular segment-shaped parts which are separated via longitudinal slots, and the second part bearing point is configured via two fork limbs of a fork-shaped main body which are pushed axially into the longitudinal slots, an exterior shape of the fork limbs in the region of the second part bearing seat corresponding to an exterior shape of the circular segment-shaped parts in a region of the first part bearing seat, and the exterior shapes being arranged in a flush manner in order to configure the annular bearing seat which is stepless in the circumferential direction.

2 . The assembly according to claim 1 , wherein

the part bearing points are plugged together axially in order to configure the positively locking connection and are press-fitted in order to configure the non-positive connection.

3 . The assembly according to claim 1 , wherein

connector wires of the slip ring module which are connected to the at least one slip ring configured to energize the rotor windings are integrated into the second part bearing point, and are routed through the bearing point in the connected state of the two-part bearing points.

4 . The assembly according to claim 1 , wherein

the first part bearing point is configured as a shaped, axial end of the rotor shaft.

5 . The assembly according to claim 1 , wherein

the main body has a fork bridge, which connects the fork limbs, and a fork shank, onto which the at least one slip ring is pushed and to which the at least one slip ring is connected mechanically.

6 . The assembly according to claim 1 , wherein

the slip ring module has two slip rings and two connector wires, the fork limbs having through openings, through which one connector wire is routed within a fork limb.

7 . The assembly according to claim 6 , wherein

the slip rings, the main body and the connector wires are connected mechanically via a casting compound with the configuration of the single-part slip ring module.

8 . The assembly according to claim 1 , wherein

the two circular segment-shaped parts are connected mechanically via a web which is pressed in between the fork limbs after the part bearing points are plugged together in order to configure a non-positive, press-fitted connection.

9 . A rotor for an electrically excited electric machine, comprising:

a rotor core;

rotor windings which are held by the rotor core;

two bearings; and

the assembly according to claim 1 .
