Paper Title:
The Friction and Wear Behavior of a Spherical Plain Bearing with the Copper Grid Composite Liner under Swivel and Tilt Swinging Conditions
  Abstract

Experiments were carried out to investigate the tribological properties of spherical plain bearings with copper grid composite liners filled PTFE under two contact pressures(40MPa,60MPa), four oscillating frequencies (1.2Hz, 1.8Hz, 2.4Hz, 3.0Hz) and two swinging conditions. With the help of SEM, EDS and Three-dimensional morphology profiler, the wear mechanism was analyzed. The results indicate the coefficients and wear depths under tilt swinging condition are higher than those of swivel swinging. While the friction temperature show the contrary trend. The research discovers that the friction temperature has a great influence on tribological properties of spherical plain bearings. The analysis demonstrates that the main wear mechanisms are the adhesive and abrasive wear under the two swinging conditions and extrusive wear exist also.
