ABSTRACT:
An inductor for inductively heating bearing surfaces of a crankshaft is machined from a block of copper to provide parallel, closely spaced and integrally joined inductor block portions having machined coolant passages therein. The machined inductor is rigidly supported between juxtaposed side plates having portions of the inner surfaces thereof machined to provide recesses which receive the inductor and in which the inductor is clampingly engaged between the plates. Positioning fingers are supported by the side plates to accurately position the active face of the inductor relative to a bearing surface to be heated, and tubular leads extend upwardly between the side plates for connecting the inductor across a source of power. An inlet conduit for coolant extends laterally between the side plates, and the tubular leads provide outlets for coolant flow from the inductor.
