Abstract

This paper discusses influences of the base material, pre-heat treatment and hardening pattern on the residual stresses of induction hardened gears with module 2 and 4 mm. The gears were hardened in a simultaneous dual frequency induction hardening process. After the hardening process, no peening was applied. Depending on the hardening pattern, base material and tempered condition, a wide range of residual stress profiles did occur, with the surface residual stresses reaching from compressive to tensile residual stresses at the tooth flank depending on the variant. In this paper, the main influence parameters on the residual stress profile will be identified.

Zusammenfassung

Dieses Paper diskutiert den Einflus von Grundwerkstoff, Vorvergütungszustand und Härtekontour auf den Eigenspannungszustand induktivgehärteter Zahnräder mit Modul 2 und 4 mm. Die Zahnräder wurden in einem Zweifrequenzverfahren induktiv gehärtet. Nach dem Härten wurde kein Strahlprozess durchgeführt. Ausgehend von Härtekontur, Grundwerkstoff und Vergütungszustand zeigte sich ein breites Spektrum an Eigenspannungsprofilen. Je nach Variante reichten dabei die Oberflächeneigenspannung von Druck- bis Zugeigenspannungen an der Zahnflanke. In diesem Paper wird der Haupteinflussparameter auf das Eigenspannungsprofil herausgearbeitet.
