Abstract
In this paper the lubricating-oil wedge which separates the tooth surfaces of involute straight spur gears is analyzed mathematically. Expressions are derived for the pressure distribution, the maximum pressuro, the minimum thickness, and the load-carrying capacity of the wedge for any phase of mating. The equation for the load-carrying capacity may give guidance to gear designers and to gear operators who are conscious of the importance of lubrication in their fields of work.Keywords
