Abstract
As a result of a huge research program the load capacity of high contact ratio gears was theoretically calculated based on the standard DIN 3990 and proved in experimental tests. This article shows the influences of high contact ratio on tooth root stress and Hertzian Pressure on the flanks. Test results of theoretical calculation and test runs are compared. An indication of how to use DIN 3990 for special tooth geometries such as high contact ratio spur or helical gears is given. In addition it is shown how to improve pitting load capacity of gears with high contact and overlap ratio by non-involute modifications of parts of the flank. The disadvantages generally known for non-involute tooth profiles do not occur by this way of modification.
