EVALUATION TESTS OF ARYLUREA-SILICONE GREASES IN AIRCRAFT EQUIPMENT

摘要

Several types of arylurea-silicone greases have been evaluated in various types of test equipment. Some of the tests were conducted with actual aircraft components, while other tests consisted of mock-ups of various aircraft systems.nArylurea-silicone greases gave good performance in the following high temperature applications: airframe oscillatory bearings, electric motor bearings, low speed roller bearings, instrument bearings.nArylurea-silicone greases did not function satisfactorily in screw jack actuator applications and in high speed ball bearings.nThe type of application, equipment design, materials used in construction, and the surrounding environment all were found to be significant factors influencing the success or failure of arylurea-silicone greases to function as lubricants.
