Turbomachine comprising a rear integrated electrical machine

A turbomachine comprising:

• a low-pressure shaft extending along an axis (X-X) of the turbomachine which defines a front and a rear;
• a turbomachine stator supporting the low-pressure shaft by bearings including a rear bearing;
• an electrical machine located at a rear portion of the turbomachine and including a rotor disconnectably driven by the low-pressure shaft, and a stator attached to the stator of the turbomachine;
• a journal for supporting the rotor of the electrical machine, the journal including a shaft segment releasably attached to a rear end of the low-pressure shaft by extending the low-pressure shaft, a frame to which the rotor of the electrical machine is attached and which surrounds the shaft segment, wherein the stator of the electrical machine surrounds the rotor of the electrical machine;
• at least one rotary bearing mounted between the frame and the shaft segment;
• and
• a sleeve that is axially mobile about the low-pressure shaft and/or the shaft segment that is rotationally connected to the low-pressure shaft and the shaft segment, and provided with rearwardly extending coupling device capable of being engaged with forwardly extending complementary coupling device of the frame.
