Abstract (en)
[origin: WO2004079227A1] The invention relates to actuators used to displace an anode frame of an electrolysis cell used to produce aluminium. According to the invention, said actuator (100, 100') comprises a sheath (120) provided with an opening (121), an actuating rod (140) comprising an axial cavity (141) and threading (142) and which can be displaced in the opening, a drive screw (130) which is inserted into the cavity and which can cooperate with the threading in order to cause the displacement of the rod (140) in the sheath (120) and in the opening (121), a toothed drive wheel (150) coupled to the drive screw (130), and an endless screw which can be connected to the shaft of a drive motor (200) and which can cooperate with the drive wheel (150) causing it to rotate. The invention is characterized in that the centre distance between the axis R of the drive wheel and axis V of the endless screw is 100 - 350 mm, and in that the reduction ratio RR between the endless screw and the drive wheel is between 300:1 and 80:1. The inventive actuator makes it possible to achieve, simultaneously, relatively high traction power and forces, while taking up only a relatively limited volume.
