FIELD: machine building.
SUBSTANCE: device consists of housing (1) with covers (2) and (3), where on the bearings (10) and (11) the epicyclic transmission is installed, where the screw (12) contacts with the nut (15) through the rollers (13). The screw (12) has a threaded section and guiding cylindrical section "D", conjugate to the hole "E" of the sleeve (4). At the screw end the fitting assembly (18) is located. The bearings (10) and (11) are installed on the external surface of the nut (15) of the epicyclic roller transmission, and the space inside the housing between bearings is protected by seals (25) and is intended for arranging of the embedded electric motor with the hollow rotor.
EFFECT: decrease of axial dimensions of the device.
