Abstract:
The paper describes an investigation of lubricating capabilities in bearing and gears of unsubstituted polyphenyl ethers and a comparison of these ethers with conventional lubricants . These investigations were performed under severe thermal, oxidative and ionizing radiation stresses. The results show that all lubricants suffer an appreciable decrease in load carrying capacity at elevated temperatures, but preserve their lubricating properties under the most severe environments, provided the flow of oil to the load bearing elements is not impeded . Since the flow of oil is highly affected by degradation due to heat, oxidation and radiation, the stabilities of unsubstituted polyphenyl ethers were compared in these tests to conventional oils. The results showed a great superiority of the polyphenyl ethers. It was noted also that the effect of ionizing radiation at levels below 1 x 109 ergs/g is negligibly small, and in this radiation range the main causes of lubricant degradation are heat and oxidation.
