摘要： Systems and methods are presented for automated induction hardening of crankshaft bearings while controlling the crankshaft TIR, in which one or more first bearings are hardened by induction heating and quenching, followed by measurement of the crankshaft TIR. The measured TIR is then evaluated and one or more second bearings are hardened using a second induction heating power profile and a second quench flow profile, at least one of which is selectively adjusted according to the measured crankshaft TIR. In this manner, the hardening of the second bearing(s) can counteract any bending or warpage caused by the first hardening process to control the resulting final TIR of the crankshaft.

摘要： An apparatus and method for hardening the concentric main bearing surfaces and orbital pin bearing surfaces of a crankshaft for an internal combustion engine rotatable about the common center axis of the main bearing surfaces. The apparatus comprising an inductor for encircling each one of the surfaces to be hardened over at least a portion of the surface and riding on the surface where the inductors are connected to a high frequency power source with a power controller to cause the power source to direct a given power to the inductor at given rotational heating positions of the crankshaft. A quench chamber is associated with the inductor and has outlet orifices directed toward the surface encircled by the inductor. A supply of quenching liquid with a flow controller directs a given quantity of quench liquid against the surface after the surface has been inductively heated by the inductor. A master controller creates output signals to control the power controller for each of the surfaces encircled by an inductor and at rotational positions in arcuate power control increments of less than 30 degrees, but preferably about 10 degrees. The master controller may also provide incremental pulsed quench control at rotational positions in arcuate quench control increments of less than about 360 degrees. The apparatus and method includes a first multi-surface hardening station with encircling inductors for all of the main bearing surfaces, a second multi-surface hardening station with encircling inductors for pins 2 and 3 and a third multi-surface hardening station with encircling inductors for pins 1 and 4. Total indicator run out (TIR) is measured after the first station to adjust the heating process in the third station to produce a straight crankshaft.

摘要： A pusher furnace includes furnace sections having respective susceptors, a slide rail extending through the furnace sections for sliding pusher plates thereon and an alignment assembly for aligning the susceptors and slide rails of adjacent furnace sections. A support structure spaces the susceptors from insulation therebelow to protect the insulation from degradation from contact with the susceptors. The susceptors are slidably mounted on the support structure to accommodate thermal expansion and shrinkage of the susceptor. The upstream end of the slide rails have beveled upper edges to help prevent the pusher plates from catching thereon. The upstream ends are also laterally tapered to reduce the degree of force encountered should a pusher plate catch thereon. Adjacent insulation members have expansion joints filled with a refractory felt. The susceptors slidably and sealingly engage exhaust ports to allow for thermal expansion and shrinkage of the susceptor without damaging the exhaust port.

摘要： A semi-liquid metal processing and sensing device comprising a crucible that is at least partially encircled by at least one induction coil. The one or more induction coils can be water cooled. The one or more induction coils can be designed to generate a variable power and/or variable frequency magnetic field which can be modulated to control the cooling of a molten metal charge in the crucible from the liquidus temperature to a selected heat content, resistivity and/or viscosity. The magnetic field can be designed to induce toroidal agitation of the metal charge in the crucible. The semi-liquid condition is sensed and can be actively controlled by the induction power supply via real time or non-real time analysis of electrical feedback signals that are obtained from the induction coil.
