    Abstract

    This paper presents some of the physical concepts perceived in the establishment of the lubricating oil wedge which separates the mating tooth surfaces of high-speed gears. (See Fig. 1 for an indication of the location of the oil wedge.) Emphasis is placed on the presentation of the physical concepts involved rather than on the mathematics of the subject matter. The work presented may be divided into the following four parts: 1. The establishment of the oil wedge and its associated load-carrying capacity for oil wedges of various shapes, with and without normal and tangential surface motions. 2. Factors which influence the load-carrying capacity of the oil wedge between gear tooth sufaces. 3. Suggested features of the lubricants and gear materials which may be improved upon to give higher tooth load-carrying capacities. 4. Summary.
