Abstract

Porous oil retainer is a key factor to ensure good lubrication of the inertial navigation bearings. The PTFE/PI porous retainer made of the original recipe and process preparation, in the high-speed operation, will appear serious wear, high temperature rise, a large amount of oil loss in the micro pores due to expansion and other issues. These lead to the lubrication life greatly reduced. It cannot meet the high-speed and long-time operation requirements of high-precision bearings. In this paper, a improved porous retainer composite is developed, which is using porous PI as the matrix , graphene as the enhancing modified additives, and PTFE as lubricating modified additives. The improved porous retainer composite is prepared by using the constant volume sintering method. The effect of graphene addition on the mechanical properties and tribological properties of porous retainer composites is studied. The results show that the high strength properties of graphene and the good wear resistance performance of PTFE improve the porous polyimide retainer composites.
