The stability of lubricating grease performances is a significant factor that restricts the long-term storage reliability of aerospace electro-mechanical servo actuators. The rheological properties of lubricating grease can directly affect the transition characteristics of servo actuators. Accelerated degradation test at high temperature stresses is designed and carried out. Three grades of lubricating grease with different base oil systems, including soap based, non-soap based and mixed lubricating grease are investigated for their theological properties. The rheological properties of different lubricating grease changed in thermal aging time and temperature stress are analyzed. It is found that the viscosity of lubrication dose not change unidirectionally with the increase of thermal aging time. In addition, the rheological properties of mixed lubricating grease at high temperature is better than that of soap based lubricating grease and non-soap based lubricating grease, which is valuable to evaluate the properties of lubricating grease during long-term storage of aerospace electromechanical servo system.
