TESTS OF DRY COMPOSITE LUBRICATED GEARS FOR USE IN AN AEROSPACE ENVIRONMENTAL CHAMBER
ARO INC ARNOLD AFS TN
Pagination or Media Count:
This report contains the results of a test program set up to determine the operational characteristics of dry composite lubricated gears. Two diametral pitch sizes, 7 and 12, and two gear materials, nitralloy steel and nodular iron, were tested. Three dry composite lubricants and one low vapor pressure grease were tested. All three dry composite lubricants provided adequate lubrication for periods of up to 300 hr at 100 rmp with very little wear of either load gears or lubricating idlers. The MoS2-fortified, grease- lubricated failed after 40 hr of operation.
