METHOD FOR REDUCING FRICTION AND STARTING TORQUE IN SLIDING BEARINGS Russian patent published in 1999 - IPC

FIELD: machine engineering, namely reduction of friction in bearings. SUBSTANCE: method comprises steps of introducing into gap between rubbing surfaces of shaft and insert of sliding bearing antifriction material including predetermined-size spheroidal microparticles; selecting minimum diameter of microparticles in dependance upon mean height of micro irregularities of rubbing surfaces; selecting maximum diameter of microparticles according to minimum value of gap between rubbing surfaces while taking into account fit allowance of shaft and insert. EFFECT: enhanced possibility of lubricating bearings. 6 cl, 2 dwg, 1 tbl
