摘要： A single-shot inductor is provided to induction heat treat a complex workpiece that has an at least partially cylindrical component with its central axis coincident with the central axis of a circular component and connected at one end to the circular component with a diameter larger than the diameter of the at least partially cylindrical component. The single-shot inductor has a single crossover inductor section connected to the first ends of two longitudinal leg inductor sections with the second ends of the two longitudinal leg inductor sections connected to a collar inductor section that surrounds the entire circumference of the at least partially cylindrical component when the complex workpiece is loaded in the single-shot one-turn inductor for an induction heating application. Alternatively the single-shot inductor may have two collar inductor sections interconnected between two longitudinal leg inductor sections where one of the leg sections can accept a supply of alternating current.

摘要： A master inductor circuit is connected to an alternating current power source and a passive inductor circuit are assembled as a separable split inductor assembly to form at least one pair of a master heating inductor and a passive heating inductor where the master and passive inductor circuits are electromagnetically coupled without physical connection. A bearing component can be brought into the presence of the magnetic flux field created by the master and passive heating inductors to simultaneously induction heat one or more bearing features on the bearing component with subsequent quenching down austenitized bearing features on the bearing component.

摘要： An apparatus and process are provided for multi-frequency induction heat treatment of workpieces including gears. High frequency power is applied to an induction coil that surrounds the workpiece so that a high frequency magnetic field couples with the workpiece to inductively heat the workpiece. A C-core inductor is coupled to a coil that has low frequency power applied to it. The workpiece is inserted in a gap in the C-core inductor magnetic circuit so that it experiences low frequency Joule effect heating when the low frequency current is applied to the coil coupled with the C-core inductor. Alternatively the workpiece may be inserted around the C-core inductor when the workpiece has an opening.

摘要： An induction coil with inner and outer coil segments joined together by a transition segment is arranged so that the outer coil segment generally inductively heat treats an annular outer region of a workpiece positioned under the coil, the inner coil segment generally inductively heat treats an annular inner region of the workpiece, and the transition segment traverses at least a portion of the width of the overall annular region of the workpiece to be heat treated. Relative arrangement of inner, outer and transition coil segments provides for controlled induction heat treatment across the overall annular region such as the gear teeth region of an intersecting axes or non-intersecting and non-parallel axes gear.
