Online basic seminar

This online seminar will present the results of test bench investigations on a large gear (a = 508.33 mm, mn = 25 mm) and on standard stress test rigs (a = 91.5 mm, mn = 4.5 mm). This includes analysis of the effect of changes due to micropitting on tooth flanks manufactured with a 5-axis machining center
In addition to pronounced micro- and macro-geometric surface properties, basic measurements also reveal characteristics of the manufacturing process. Compared to large-module gears with similar profile modifications from previous projects, the step test shows clear profile form variations along with shaving marks. These can be attributed to premature meshing impacts as a result of negative profile angle deviations. In contrast, scouring measured in the micropitting area correlates well with small modules and gears from previous projects. With regard to micropitting, the 5-axis milled gears show similar wear depths but with a greater wear area. Reducing the injection temperature from 90 °C to 60 °C leads to a smaller micropitting area due to optimized lubrication conditions, especially on the micro-geometric surface of the 5-axis milled, large-module gears. However, no correlation of micropitting wear due to reduced surface roughness after vibratory grinding could be observed.
Target audience
This seminar is intended for anyone who is interested in the results of the FVA 286 V research project.
