NOVELTY - Polytetrafluoroethylene (PTFE) fabric pad and dry film combined friction pair comprises a polytetrafluoroethylene fabric pad and a dry film are rotatably matched to form a friction pair, where the polytetrafluoroethylene fabric pad working surface polytetrafluoroethylene content is greater than or equal to75%; the dry film thickness is controlled to be 6-12 m, and the dry film is molybdenum disulfide dry film lubricating layer, the dry film surface Ra after forming is less than or equal to0.4. USE - The PTFE fabric pad/dry film combined friction pair is useful in self-lubricating bearing joint applied in high speed rotating working condition (claimed). ADVANTAGE - The PTFE fabric pad/dry film combined friction pair can be well adapted to high speed rotating condition, keeps a very low temperature rise rate in the friction and wear process, applied to the self-lubricating joint the high speed rotating working condition of the bearing, and can prolong the service life of the self-lubricating bearing joint. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Processing the PTFE fabric pad and dry film combined friction pair comprising (i) friction surface processing: adhering the PTFE fabric pad with glue film, and pre-curing, the pre-curing process has a certain pressure, (ii) processing the grinding surface: spraying and processing the surface of the PTFE fabric pad; after finishing spraying, pre-curing, after the final high temperature curing, obtaining the dry film, the pre-curing temperature is lower than the final curing temperature, and (iii) assembling and processing: assembling the friction surface and the grinding surface, heating and solidifying to form, and dip coating or spraying release agent on the front surface of the grinding surface assembly; and (2) A self-lubricating joint bearing, comprising a bearing outer ring and a bearing inner ring, the outer ring spherical surface is provided with a PTFE fabric pad, the outer surface of the inner ring is coated with dry film, the PTFE fabric pad and the dry film are combined to form a friction pair, where the friction pair is one of the PTFE fabric pad and dry film combined friction pair. DESCRIPTION OF DRAWING(S) - The drawing shows a processing schematic diagram of a PTFE fabric pad and dry film combined friction pair.
