FIELD: railway transport; rail lubricating device installed on rail vehicles. SUBSTANCE: ski has vertical and horizontal interconnected flanges whose inner surface are separated by through longitudinal slot or clearance. Inner surface of vertical flange is made convex in cross section and is provided with slot with hole to deliver lubricant. EFFECT: reduced consumption of lubricant, improved efficiency of lubrication of rail head side surface by application of lubricant to rail side surface at preset distance from roll surface at vertical vibrations of rail and different degrees of rail head wear. |
