Improvement of Contact Fatigue Strength of Gears by Tooth surface Modification Processing

摘要

In this paper, it combined with the caburized gear with the existence of manganese phosphate conversion coating and the gear tooth fatigue experiment of the system gear was conducted using a basic experiment and automatic shift of gear tooth fatigue of a simple substance gear pair. Consequently, it was proved that the gear which gave the manganese phosphate conversion coating had high pitting proof load capability by improvement in the initial familiarity nature of a gear pair, an improvement of lubricating oil holdout, and direct contact prevention of metal. Analysis of the pitting-proof fatigue characteristics of manganese phosphate conversion coating processing specification and the gear tooth wear characteristic etc. performed the engagement gear by one of the two or both in the experiment.
