Latest Patents

His latest patents include a "System and Method for Crankshaft Hardening" and an "Apparatus and Method for Hardening Bearing Surfaces of a Crankshaft."

In the first patent, McKinney presents a sophisticated system for the automated induction hardening of crankshaft bearings while effectively controlling the total indicator run out (TIR). This process involves induced heating and quenching of the first set of bearings, followed by precise measurement and evaluation of the TIR. The technique allows for selective adjustment in the hardening of subsequent bearings to counteract any deformities caused in the initial hardening, thereby ensuring optimal crankshaft performance.

The second patent details an apparatus designed for hardening the concentric main bearing surfaces and orbital pin bearing surfaces specifically for internal combustion engines. This innovative apparatus incorporates a high-frequency power source that directs heating to the crankshaft at defined rotational positions. It includes multiple hardening stations equipped with inductors to cater to different bearing surfaces, while also measuring the TIR post-hardening to achieve a straightened crankshaft.
