The invention relates to a device for fixing a rotor (1) to a drive shaft (4) which is connected to a motor, the drive-shaft (4) end (3) turned away from the motor and provided for holding the rotor (1) being conical. Said device has a spring chuck (2) which is substantially rotationally symmetrical, and is arranged around the conical end (3) of the drive shaft (4), and is slotted parallel to the axis starting in each case from one end surface of the spring chuck (2). The inside of the spring chuck (2) is conical and the conical shape corresponds to the shape of the cone (3) of the drive shaft (4), and the outside of the spring chuck (2) is substantially cylindrical, and has a stop surface (9) perpendicular to the axis of rotation of the spring chuck (2) on the spring chuck (2) end turned away from the motor, for frictional connection with a clamping screw (12) engaging in an axial bore of the drive shaft (4). To ensure, after changes in temperature of the individual components or after temperature compensation of components which have great differences in temperature during assembly, secure fastening of the rotor (1) to the drive shaft (4) a spring arrangement (11) compressible in the axial direction is arranged between the stop surface (9) and the screw top of the clamping screw (12), and a friction element (15) is arranged between the axial stop (5) and the rotor (1).
