摘要

This Final Report for a 39.5-month contract contains the results of several projects conducted on the program. The first project was a continuation of a long-term repeatability study on the Four-Ball wear testers. The work was done to assure that the two test machines were constant in performance. The data confirm that the machine performance was as constant as could be statistically expected, both from machine to machine and for each machine as a function of time. The second project was to conduct Four-Ball wear tests on various oils and greases to determine the ability of the lubricants to prevent wear at various conditions of speed, load, and temperature. Data from 1,111 tests on 200 lubricating materials are reported. The third and fourth projects were to determine performance lives of various greases on the Pope and Navy spindles. Equipment descriptions and test results are included. The fifth project was grease testing in the Sikorsky rigs. These rigs are described and the test results presented. The sixth project discussed was the long-term testing of lubricant compact materials in ball bearings.
