<p>A gearbox for a centrifuge, such as a decanter centrifuge with a rotatable bowl (1) connected to a housing (31) of the gearbox, is driven at a first speed by a first external driving means (11) and a helical conveyer (2) coaxially arranged for rotating therein at a second rotational speed. Said gearbox is comprising a three-stage epicycloidal gear train. The relative speed difference between the bowl and the conveyer is by means of the gearbox according to the invention achieved with smaller internal and external losses than hitherto known. Just by reversing the direction of the conveyer sun wheel the bowl can be brought to run faster or slower than the conveyer.</p> |
