TURBOMACHINE EQUIPPED WITH AN ELECTRIC MOTOR AND COUPLING MEANS BETWEEN A SHAFT OF THE TURBOMACHINE AND A SHAFT CONNECTED TO THE ELECTRIC MOTOR

Abstract

The invention relates to a turbomachine, in particular for aircraft, comprising: - a low-pressure shaft (2) extending along a longitudinal axis (X) to a rear end (3), - a turbomachine stator (4) supporting the rear end by means of a rear bearing (5) arranged in a first lubrication chamber (8), - an electric machine located at the rear of the turbomachine, and comprising a stator (22) and a rotor (23) capable of being driven in rotation by the low-pressure shaft via a connecting shaft (25).According to the invention, the connecting shaft and the rear end are rotationally fixed via coupling means (26) located outside the first enclosure, the low-pressure shaft being axially movable relative to the connecting shaft via the coupling means (26) which comprise first splines (27) carried by the connecting shaft (26) and engaging with complementary second splines (28) carried by the low-pressure shaft.
