Coming Clean on Gearbox Lubrication

Design and manufacture of gears is among the most complex and difficult disciplines of the industrial arts. From initial conception to machining and finishing, making gears ain't bean-bag. And guess what? Once those gears roll off the assembly line, it doesn't get any simpler. That's because gears - the metal ones at least - require the correct lubrication in order to prevent - or delay as long as possible - such things as wear, scuffing and Hertzian fatigue.
