MOTOR-AXLE-MOUNTED BEARING Russian patent published in 2003 - IPC

FIELD: mechanical engineering; friction units. SUBSTANCE: proposed bearing has two shells; first shell is provided with port; each shell has bearing bronze layer. Inner surface of bearing layer has projecting bronze plugs fitted in holes and provided with micro-porous polymer inserts-tablets at self- lubrication effect. Bronze plugs ensure smooth distribution of lubricant on working surface. Outer surface of bearing layer has holes extending to porous insert-tablet for supply and storage of lubricant, replacement of bronze plugs and removal of heat from friction surface.
