ABSTRACT:
A method for manufacturing a novel gear fit article that includes metal plating the surface of an annular steel work is disclosed. The plating is made of copper to prevent nitriding of the underlying steel. The plated steel work is gear cut to form internal teeth of exposed steel. The annular gear is nitrided to harden the teeth and, in the process, softens the metal plating. Thereafter, the annular gear is shrinkage fitted into a rotor body to form the novel gear fit article.
