METHOD OF RECLAIMING SUPPORT OF FREIGHT CAR BOGIE PARTS Russian patent published in 2010 - IPC B23P6/00 B23P15/20 

FIELD: process engineering.

SUBSTANCE: invention relates to repair of railroad rolling stock and can be used at repair enterprises. Worn-out areas of the part support surfaces are precoated, spread with glue and filled with a layer of polymer metal composite material in amount sufficient for filling cavities so that worn-out areas are flush-leveled with the part support surface. Protective strip is hardened and arranged at the center of prepared part surface to completely cover said area. Said layer backed out via pressed protective strip, vibrator is used to compact polymer metal composite material layer. Protective strip is heated to composite material polymerisation temperature of 120-150°C and kept for 30 min at said temperature to allow polymerisation of composite material. Then blunt hole is bored for check pin. The latter is fitted in place and welded to protective strip wear-resistant surface for it to be cooled in ambient conditions.

EFFECT: increased efficiency and MTBR.
