Influence of the type of gearing to pitting damage

Abstract

The most common damage of operating tooth face is fatigue of material, caused by creation of pitting. At the beginning of the paper is briefly characterized the emerging pitting and what is the decisive factor in its creation. The main gear parameters are explained, which affect the damages caused by pitting with focus on C–C gearing. Testing methodology is presented on Niemann’s stand at three different layers of working load. Attention is focused mainly on the influence of pitting damage in regard to the type of the gear, since the creation of pitting at the same working load and other operating conditions occur within a different number of cycles. Results of the experiment are compared with the results already obtained in involute gearing.
