FABRICATION OF THIN-WALL SELF-LUBING ANTIFRICTION BEARING BY COILING WITH METAL TAPE

摘要

FIELD: process engineering.SUBSTANCE: invention relates to production of parts by coiling in machine building. Proposed process consists in brass 1-2 mm deep tape with grooves pre-rolled on its working surface and filled with solid-lubricant graphitized polymerizing material is wound, turn-to-turn, onto mandrel to get a tubular workpiece. Then, solids of revolution are placed thereat and locked by anaerobic material. Friction units are cut off over antifriction bearing width.EFFECT: better manufacturability, lower friction factor, increased MTBF.7 dwg
