EXTREME PRESSURE LUBRICATION Available to Purchase

EXTREME PRESSURE OR EXTREME TEMPERATURE LUBRICANTS have been developed for two main fields—the lubrication of hypoid gears and as lubricants in metal working and it is of some interest to see how this development has occurred. Musgrave, in a most comprehensive paper on the Development and Lubrication of the Automotive Hypoid Gearf defined a hypoid as “a special form of spiral bevel gear in which the pinion axis is offset from the axis of the ring gear” and he pointed out that such gears had the advantages of quietness in operation, particularly at high speeds, greater tooth strength capacity, greater dependability and were more economic to produce as well as allowing lower body designs than spiral bevel or worm gears.
