Abstract
A drive system having an electric machine, by which a drive shaft of a drive assembly is capable of being driven in rotation and/or electric energy is capable of being recovered during the rotation of the drive shaft. The electric machine has a stator arrangement and a rotor arrangement connected or connectable to the drive shaft for joint rotation about an axis of rotation. A positive guidance arrangement is provided via which the rotor arrangement and the stator arrangement are guided relative to one another when a relative axial movement is carried out for assembling or dismantling the electric machine.
Claims43
A drive system, comprising:
- a drive shaft;
- an electric machine via which the drive shaft is drivable in rotation and electric energy is capable of being recovered during rotation of the drive shaft, the electric machine having a stator arrangement and a rotor arrangement connectable to the drive shaft for joint rotation about an axis of rotation;
- and a guidance arrangement arranged to guide the rotor arrangement and the stator arrangement relative to one another when a relative axial movement for assembling and dismantling the electric machine is carried out, the guidance arrangement comprising a guidance unit, guidance interaction being generated between the rotor arrangement and the guidance unit which is positionable in a predetermined position on the drive shaft.
A method for assembling and dismantling a rotor arrangement and a stator arrangement of an electric machine, by means of which electric machine a drive shaft of a drive assembly is drivable in rotation and electric energy is recoverable during the rotation of the drive shaft, the method comprising the step of moving the rotor arrangement and the stator arrangement relative to one another, in a direction of an axis of rotation, during which relative movement the rotor arrangement and the stator arrangement are guided relative to one another, the relative axial movement between the rotor arrangement and stator arrangement for assembling the electric machine being carried at before mounting the rotor arrangement on the drive shaft and before mounting the stator arrangement on a fixed subassembly.
