INSTALLATION FOR MANUFACTURING BALL BEARING CAGES OF COMPOSITE MATERIALS BY CENTRIFUGAL CASTING

摘要

The invention relates to an installation for manufacturing ball bearing cages of composite materials by centrifugal casting, especially meant for manufacturing ball bearings for aircraft industry. According to the invention, the installation comprises an upper subassembly (A) for preparing the composite material embedding reinforcing graphite particles, said subassembly comprising an electric furnace (9) for preparing the composite material, said furnace being provided with a bottom pouring device (11) and a mechanical stirrer (7), a jarring machine (5) linked with a grading screen (4) being provided for dosing the reinforcing elements, and a lower subassembly (B) comprising a vertical centrifugal casting machine provided with a mould (18) supplied by means of a lever (13) with the smelt included composite material from the upper subassembly (A).
