FIELD: transport.
SUBSTANCE: motor reduction gear is fixed on base part (50) and has screw (40) which is actuated by drive gear located on it. Drive gear (42) is rotated by actuating element (500) of drive assembly (20). Device (30) functionally interconnects actuating element (500) and drive gear (42). Drive assembly (20) is flange mounted to the device (30). Drive gear (42) is mounted on holder on supports. Holder is fixed on base part (50) and serves as carrying element for the said device (30). The holder has one radial hole via which actuating element (500) of drive assembly (20) and drive gear (42) are interconnected. Assembly method consists in the following: at first, the first main unit is assembled and separately - the second main unit (3), then the first and the second (3) main units are joined. The first main unit consists of screw (40), drive gear (42) and holder, and the second main element - of actuating element (500), drive assembly (20) and the device (30).
EFFECT: simplification of motor reduction gear assembling due to simplification of design and reduction of necessary parts quantity.
