Tribological aspects of contemporary gear materials

Abstract

The aim of this paper is to determine the problems of selecting gear materials due to tribological aspects as meta-analysis. Gear performance is profoundly influenced by tribology. Gear design is a process of synthesis in which gear geometry, materials, heat treatment, manufacturing methods and lubrication are selected to meet the requirements of a given application. This paper will give some answers to these questions and will show how the gear design first approaches the problem of material selection and heat treatment technology, as influenced by the performance, life requirements and reliability of the gear set due to tribological aspects. The research shown in the paper will also enhance the ability both of the gear-design engineer and the gear metallurgist to better grasp their relative, related critical roles in the exciting world of gear processing, heat treatment and inspection. Interspersed of the research shown in the paper will be examples of gear-related problems, failures, and improved processing procedures. Analyses and comments on a number of relevant failures are given.
