SELF-LUBRICATING BEARING MATERIAL AND SLIDE BEARING WITH SUCH BEARING MATERIAL.

摘要

A SELF-LUBRICATING BEARING MATERIAL IS DESCRIBED, AS WELL AS A FRICTION BEARING MADE WITH SUCH MATERIAL, WHICH EFFECTIVENESS, EVEN WITHOUT LUBRICANT, HAS BEEN IMPROVED IN SUCH A WAY THAT WITH A LOAD AND SPEED VALVES OF A HIGH VALUE, UP TO 6 MPA / M / S. THE SELF-LUBRICATING BEARING MATERIAL SHOWS A PLASTIC MATRIX THAT CONTAINS PTFE WITH FILLING SUBSTANCES THAT HAVE PBO AND AT LEAST A METAL FLUORIDE. THE PROPORTION OF PBO IS FROM 15 TO 55% BY VOLUME AND THE PROPORTION OF METAL FLUORIDE FROM 0.1 TO 14% BY VOLUME. AS METAL FLUORS, CAF {SUB, 2}, PBF {SUB, 2} AND MGF {SUB, 2} ARE PREFERRED. IT IS ALSO POSSIBLE TO ADD OTHER FILLING SUBSTANCES SUCH AS HARDENED SUBSTANCES, PIGMENTS OR FIBER MATERIAL. THE PROPORTION OF OTHER ADDITIVES CAN BE UP TO 40% BY VOLUME OF SUBSTANCES OF PBO FILLING AND METAL FLUORIDE.
