FORMATION AND CONTROL OF A PISTON RING PROFILE DURING OPERATION.

Author(s) : FENG Q., YANG S.

Summary

AN EXCELLENT SURFACE PROFILE OF A PISTON RING IS SELECTED BY MEANS OF THE SIMULATING CALCULATION OF THE FILM THICKNESS AND THE OIL CONSUMPTION BETWEEN THE RINGS AND LINERS. ON THE BASIS OF DYNAMICS AND TRIBOLOGY OF RINGS, A PRACTICAL MEASURE IS PUT FORWARD IN WHICH THE LOCAL SURFACE OF A COMMON RING IS HARDENED BY LASER. INSTALLED IN A Z-0.2/10 AIR COMPRESSOR, THE HARDENED RINGS WERE TESTED FOR 3,000 HOURS. THE MEASURED RESULTS SHOW THAT THE HARDENED RINGS DO FORM AND KEEPA DESIRABLE SURFACE PROFILE, WHICH IS PROVIDED WITH EXCELLENT LUBRICATING CONDITION AND LESS OIL CONSUMPTION.
