Abstract:
An axial tension apparatus (100) for generating an axial force for actuating a clamping device, for example a chuck, by means of a drawbar (32) is specified. With the aim of being able to use a comparatively small electric motor for actuating the clamping device while reducing the necessary stroke times, the solution according to the invention provides that the axial tension apparatus (100) has an electrically operated clamping motor having a stator (11) that does not corotate when the spindle rotates and a rotor (12) that corotates when the spindle rotates, a motor shaft (13) connected to the rotor (12) for transmitting the rotary movement of the clamping motor, a bearing housing (18), within which there is arranged a spindle nut (28) that is axially displaceable to a limited degree by means of a spring mounting (17), and a clutch (21) for the selective coupled transmission of a rotary movement between the motor shaft (13) and the bearing housing (18), wherein the clutch (21) is biased into a closed position, so that motor shaft (139 is rotationally coupled to bearing housing (18), wherein the drawbar (32) has an external thread (34) which is engaged with the spindle nut (28) such that the drawbar (32) and the spindle nut (28) form a screw drive, by means of which the motor shaft (13) is connected to the drawbar (32) in a rotatable manner.
