ABSTRACT:
A yoke-trunnion universal joint has a plastic anti-wear coating disposed between the sleeve and trunnion for lubrication, anti wear and absorbing vibration. A combining means combines the plastic anti-wear coating with sleeve or trunnion tightly. The plastic anti-wear coating is made by nylon or polytetrafluoroethylene. The universal joint has a simple structure, long working life, low operating noise and cheap manufacture cost. The most advantage is that the universal joint needs not oil or grease for whole working life. It is an oil or grease free and maintenance free universal joint.
