Abstract
In a process for the induction hardening of crankshafts with at least one connecting-rod pin and with at least two main bearings, in particular for the hardening of the at least one connecting-rod pin, by means of a contactlessly operating inductor, the crankshaft performs a rotational movement during the hardening of the at least one connecting-rod pin. The center axis of the at least one connecting-rod pin to be hardened is used as the axis for the rotational movement of the crankshaft.
Claims20
A process for induction hardening at least one connecting-rod pin formed on a crankshaft by means of a contactlessly operating inductor, the crankshaft having the at least one connecting-rod pin and at least two main bearings, comprising the step of:
- performing a rotational movement of the crankshaft during the hardening of a first one of the at least one connecting-rod pin, the first one of the at least one connecting-rod pin having a central axis, the central axis of the first of the at least one-connecting-rod pin being hardened being used as an axis for the rotational movement of the crankshaft.
An apparatus for induction hardening of at least one connecting-rod pin of a crankshaft, said connecting pin having a central axis, comprising:
- at least one inductor adapted to be disposed adjacent to the at least one connecting-rod pin to be hardened;
- at least one rotating device for rotating the crankshaft;
- and
- at least one adjusting device associated with the at least one rotating device and which receives the crankshaft and sets the central axis of one of the at least one connecting-rod pin of the crankshaft as an axis for the rotational movement of the crankshaft.
