The article "Improved Worm Gear Performance with Colloidal Molybdenum Disulfide Containing Lubricants" appeared in the November/December 1988 issue of Gear Technology.

Summary
Worm gear speed reducers give the design engineer considerable options, but these gear systems present a challenge to the lubrication engineer. Heat energy generated by the high rate of sliding and friction in the contact zone causes worm gears to be relatively inefficient compared to other gear types. Because worm gears operate under a boundary or near-boundary lubrication regime, a satisfactory lubricant should contain a friction modifier to alleviate these conditions.
