The invention relates to a rotational speed converter, by means of which a constant rotational speed or a continuously rising or continuously falling rotational speed change can be realized. The input rotational speed is converted by using at least three differential gearings (2, 3, 4) arranged in series, of which the two outer differential gearings (2, 3) are the same. The differential gearings (2, 3, 4) are brought into a power equilibrium in order to generate a constant output rotational speed. The power equilibrium can be disturbed by means of a speed-changing control gearing (12) that can be coupled into the power flow, in that the control gearing (12) transmits at a ratio unequal to 1:1, a continuous rotational speed increase or rotational speed decrease of the output rotational speed thus being generated. |
