Lubricants for Gear Motors, Gear Boxes and Power Tool Gearing

The rolling and sliding actions which occur in all types of gearing, such as spur, helical, worm, spiral bevel or hypoid, present a different type of challenge to lubricants compared to ball or roller bearings. Many designers, especially worm gear designers, are interested in increasing gear box efficiency. Modern designs require the most in power transfer with minimal noise and heat generation. In some cases, oils are being replaced by specially designed synthetic greases to reduce component cost by eliminating the need for seals and the machining costs associated with oil seal designs. Other gear train designs may have special operating environments including high and low temp
