Abstract

To meet high frequency oscillating and light load conditions, a kind of self-lubricating spherical plain bearing used in the helicopter main rotor system is developed. The self-lubricating liner material is designed and woven with PTFE+Nomex fiber by three dimensional weaving process.The high-performance spherical plain bearings are manufactured by extrusion process. Then the high frequency oscillating friction and wear tester is used to verify the friction and wear properties of the fabric liner. The test results show that the self-lubricating spherical plain bearings developed can meet the designed performance requirements under given operating conditions. The friction coefficient and the friction temperature are at a lower level during the whole test process, and the liner is not worn out after the life assessment time.
