Abstract

Investigations were made in back-to-back gear test rigs measuring the beneficial effects of a low oil immersion depth due to reduced drag and churning losses of the gears as well as the detrimental effects of increased gear bulk temperatures and increased gear failure risks. In these cases the oil amount required for lubrication may still be sufficient but oil cooling is often minimised. The influence of the gear immersion depth on scuffing performance of case carburised gears was determined in systematic investigations as a function of immersion depth, speed and direction of rotation. The results of the experimental investigations are presented and their introduction into calculation methods is discussed.
