An articulated spindle as used for example in a rolling mill drive has a shank the ends of which are connected to sleeves through gear-type couplings. Liquid is continually passed through each gear-type coupling for cooling and lubrication. The liquid is supplied under pressure through the shank to the couplings, passes through the couplings, and is withdrawn under suction through return conduits which rotate with the shank. The liquid is supplied by a delivery pump through a rotating joint to the shank and is withdrawn from the return conduits through the rotating joint by a suction pump.
