AUTOMATIC LUBRICATOR Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: automatic lubricator has housing, lubricant supply system, lubricant supply operating mechanism, lubricant feeder and lubricant supply control system. Lubricant feeder is arranged inside lubricator housing and is made in form of flexible is arranged inside lubricator housing and is made in form of flexible member with through holes to deliver lubricant to wheel-rail friction zone. It serves simultaneously as wheel flange-to-rail head side surface contact pickup. Housing of lubricator is hinge-and-spring connected with axle box of wheelset and is placed in engagement with lubricant supply operating mechanism. It has additional sliding contact with piezoelectric pickup and vibroacoustic emission fixing system which form lubricator control system. EFFECT: improved reliability of lubrication. 3 dwg
