Abstract

This study is an approach to investigate the transformations curve of gearing safety. Two types of failure can occur on a gear namely the bending stress and the surface pitting failure. There are many standards for gearing in used worldwide such as AGMA, JGMA, ISO, DIN, etc. but the focus of this study will be on AGMA standard. The main data for this study is the torque value applied which can be distinguished into causing bending strength or surface pitting failure. The Autodesk Inventor spur gear component accelerator was used as a tool for data acquisition based on the AGMA standard of calculations. Two gear materials with high value of allowable contact stress compared to its allowable bending stress was chosen for the study as they are predicted to have a transformation curve from surface durability to bending strength when its torque values are plotted against number of teeth. This is then repeated on various gear modules for both materials to obtain a series of combination curves useful in determining the maximum torque that can be applied on the spur gear before failures occur either by bending stress or surface pitting depending on the curve.
