Title:
【発明の名称】クランク軸のクランクピンの摺動面の誘導焼入れ装置
Document Type and Number:
Japanese Patent JPS5818968
Kind Code:
B2
Abstract:
An apparatus for inductively hardening by quenching of the running surface of bearings of a crankshaft in which the crankshafts are transported by a lifter-conveyor system to a clamp which grips the crankshaft and is pivoted about a lever arm pivotably mounted on the machine frame to a heating position below a plurality of inductors. The inductors ride on the crankshaft as it rotates to inductively heat the running surfaces. The inductors are each mounted on a linkage which also mounts a quenching shower and the linkage in turn is swingably mounted on a further lever arm which is pivotably connected to the machine frame. As the crankshaft rotates, the inductor lifts and the further lever arm lifts off a stop. The apparatus preferably includes a second clamp and set of inductors to which the crankshaft is subsequently conveyed for further treatment after hardening.
