Abstract

Spherical joints are wildly used in parallel mechanisms. This paper applied polytetrafluoroethylene (PTFE) on the surface of spherical joints, aiming at reducing both frictional resistance and clearance of this kind of joints. Firstly, three kinds of solid lubricants were coated on flat samples and their friction performances were investigated. Then the best of the three was used as friction-reducing layer filling the gap between the ball and the support in a joint. Finally, periodic rotating abrasion test was conducted on this coated spherical joint. Experimental results showed that PTFE coating could effectively reduce the clearance of ball joints and prevent components’ surfaces from rapid wear, without increasing friction significantly.
