LUBRICATION SYSTEM OF OPEN FRICTION SURFACES Russian patent published in 2004 - IPC

FIELD: railway transport. SUBSTANCE: system is designed for lubricating friction surfaces of wheel flanges and side face of rail head. Proposed system contains composite lubricating member installed in guide for translation towards friction surface to be lubricated. Said composite lubricating member is made to suit guide inform of rectangle or cylinder being pressed to friction surface and containing heat-resistant composite wearable housing whose inner space is filled with lubricant and closed from side of surface to be lubricated by antifriction floating piston carrying low-melting metal component with flux. Feed system has external guide housing secured on bogie frame, internal guide for lubricating members, guide precluding cocking and jamming of device pressing lubricating member to wheel flange, its working spring, locking device retainer, locking device spring and locking device housing with z-shaped slot and working spring plug. EFFECT: improved reliability of system. 7 cl, 2 dwg
