Method and device for producing a mechanical part, in particular a bearing ring and a part produced by said methods

A production device for producing a circular-shaped mechanical part made of a metal alloy capable of undergoing at least one thermal hardening treatment, said device comprising a rotating hollow mold (11, 41) positioned to receive a predetermined volume of the metal alloy, induction heating components to bring at least part of the metal alloy to a melting temperature (T1) and drive mechanisms to cause the hollow mold to rotate and produce a blank (26) of the mechanical part through centrifugation,

• a means for determining the predetermined volume of the metal alloy to be melted from a metal alloy bar (20), wherein the metal alloy bar is fed by a feed device to a position in the induction heating components such that at least the means for determining the predetermined volume of the metal alloy is brought to the melting temperature (T1) therein, and the predetermined volume falls into the hollow mold;
• a means (30) for cooling the blank (26) which was obtained through centrifugation of the molten alloy metal in the hollow mold and for bringing the predetermined volume of the metal alloy to a temperature second (T2), lower than the melting temperature (T1), at which the blank (26) has a malleable consistency;
• a machining mechanism to form an interior shape of the mechanical part (28);
• a temperature regulation device to bring the mechanical part (28) obtained from this blank to a tempering temperature (T3);
• and
• a means for tempering the mechanical part (28) after the mechanical part (28) is extracted from the hollow mold.
