The geared motor comprising a speed reducer of the worm screw/helical gear type and a speed reducer-driving electric motor, is characterized in that its body consists of two separate pieces (A, B) which are matingly joined and fastened to each other along an ideal vertical plane containing the axis of the motor. Between the extended parts (A', B') of the said pieces the stator (S) of the electric motor is included and firmly clamped, and the said parts are so formed that ducts (45) for cooling air to flow therethrough, are provided around the said stator. The axial shiftment of the speed reducer helical gear (4) is checked by projecting members (21, 121) integrally formed with the two pieces (A, B) constituting the speed reducer body, whereby the assembly and disassembly of the slow speed-operated shaft (2) and of the members which are associated therewith, is thus simplified. When the geared motor is employed for making a capstan device, a box (44) is provided and fastened to the speed reducer body, and contains the terminal board to which the cables for feeding electric current to the electric motor (M), the electric fan (56), and the thermostat controlling the cooling of the motor are connected, by being led through the tubes (48, 148). <IMAGE> |
