The invention relates to a cooling arrangement for a geared motor and a geared motor, comprising electric motors, gears and an adapter disposed between the electric motors and the gears. The electric motors have ducts for a cooling medium, in particular each of the motors can be flowed through by a cooling medium, in particular coolant, the motors in particular being liquid-cooled. The cooling medium flows emerging from the ducts are made to converge and are fed at least proportionately by a first distributor to the gears in order to lubricate and cool the toothing parts thereof.
