<p>The capstan comprises a fixed assembly (1), a wheelhead (2) guided in rotation about a vertical axis (ΑΑ') and a transmitter for transmitting circular motion and drive torque (4), in drive connection with the wheelhead (2) and with a central axis (3). The fixed assembly (1) comprises a horizontal plate (10), a guide shaft (12) that receives bearings (130) of the wheelhead (2) and comprises a base (120) securely fixed to cylindrical elements (11), rigidly secured to the plate. The motion transmitter (4) is cycloid and comprises at least one reducing transmission stage formed of an input element (41), driven by a member (30), and an output element (42), in meshing relationship with the toothing of the element (41) and with the wheelhead (2), the toothing of the element (41) and the toothing of the element (42) being formed from a series of toothing elements different in number in order to produce a reduction.</p> |
