FIELD: machine building. ^ SUBSTANCE: tool head consists of main case, of working slides travelling relative to case, and of servomotor installed in case. The servomotor actuates the slides via a reducer. Also the servomotor, made as a servo-driver, contains a stator installed in the main case and of a rotor rotating in the stator. The rotor carries a driven shaft mounted in two rotating supports. The supports are arranged at a certain distance from each other, also one of the rotating supports with its external ring is installed in the case of the stator, while with its internal ring it is positioned directly or indirectly on an output shaft. The head has a cartridge partially enveloping the stator from outside in axial direction and rigidly - without turn and shift-connected to the stator; also the head has a bearing cover closing the cartridge from the side of the reducer and bearing the external ring of the first rotating support. ^ EFFECT: reduced space and duration of stator case assembly. ^ 26 cl, 1 dwg |
