Method of making a composite plastic bearing

Abstract

Abstract THE INVENTION COMTEMPLATES AN IMPROVED SLIDING BEARING, AND METHOD OF MAKING THE SAME, WHEREIN A LOWFRICTION FABRIC LINER OF NON-CYLINDRICAL SHAPE IS PART OF AN OUTER-RING MEMBER WHICH HAS A SLIDING ROTATIONAL INTERFACE WITH THE MATCHING SURFACE OF INNER BEARINGRING MEMBER. ACCORDING TO THE METHOD OF THE INVENTION, PLURAL INNER BEARING-RING MEMBERS ARE FIRST ARRYED UPON A COMMON SUPPORT OR MANDREL. A BRAIDED SOCK OF LOW-FRICTION FABRIC IS SLIPPED OVER THE INNER-RING MEMBERS AND IS ALXIALLY ELONGATED TO CAUSE THE MAIN BODY OF THE SOCK TO CONFORM GENERALLY WITH THE EXTERNAL CONTOUR OF THE ARRAYED INNER RINGS. HARDENABLE PLASTIC SUCH A S EPOXY OR PHENOLIC IS APPLIED TO IMPREGNATE THE THREADS OF THE SOCK AND TO WET APPLIED REINFORCING THREADS OF BACK-UP LAYERS, RESULTING IN A SINGLE IMPREGNATED CYLINDER IN WHICH THE LINER MATERIAL IS HELD TO THE COUNTOUR OF ALL INNER RINGS, FOR CURING TO ULTIMATE HARDNESS, SEPARATE ASSEMBLED BEARINGS RESULT FORM THE RADICAL CUT-OFF BETWEEN ADJACENT INNER RINGS, AND REMOVAL OF THE MANDREL. VARIOUS FURTHER REFINING DETAILS ARE DISCLOSED.
