The main subject of the present paper is the still relatively unknown fling-off cooling method through continuous supply of the gear oil to the roots of the tooth faces to be cooled, for instance through holes connecting with a manifold inside the tooth rim. The cooling potentialities of this continuous method are compared with those of the naturally occurring “intermittent” fling-off cooling treated previously by A. de Winter and H. Blok [1]. A third fling-off cooling method is again continuous but, in contrast to that by root supply, occurs naturally in that it is brought about by the impingement of comparatively cool droplets from the oil mist in the gear casing. This method will be treated only cursorily, lacking certain experimental data to be substituted in design calculations based on the pertinent theoretical relationships.
