Bonding Behavior and Tribological Property for Self-lubricating Spherical Plain Bearings with PTFE/Kevlar Woven Liners

Li Yingchun;Qiu Ming;Miao Yanwei;Henan University of Science and Technology;Mechatronics Engineering Collaborative Innovation Center of Machinery Equipment Advanced Manufacturing;  
The liners of hybrid PTFE/Kevlar fabrics were modified with two different methods(ultrasonic wave treated and rare earth CeO2 treated).The peeling strength was measured using Instron5944 electronic universal material testing machine and hign frequency pendular friction wear testing machine,the tribological property was investigated using the spherical plain bearing tester with high swaying frequency,and worn surfaces observed by scanning electron microscope(SEM).The effects of pretreatment methods on the bonding property and tribological property of spherical plain bearings and the relation of thetribological property and film-forming behavior would be investigated.The results show that the bonding behavior of the modified bearings is improved,and its tribological property is improved as well.There is a correlation between the tribological property and film-forming behavior.When more smooth and continuous PTFE transfer film is formed in short time,its tribological property is also better.
