Effects of Different Hard Finishing Processes on Gear Excitation

Gearboxes are essential in mechanical drive trains for power transmission. A low noise emission and thus an optimized excitation behavior is a substantial design objective many applications terms of comfort operational safety. There exist numerous processes manufacturing gears, which all show different properties relation to the process variables and, therefore, differences resulting accuracy quality gear flank. In this paper, influence three hard finishing—continuous generating grinding, polish grinding skiving—on surface structure flanks investigated experimentally analyzed by application force level. tactile scanning determines flank deviations from desired geometry. torsional acceleration measurement during speed ramp-ups at load levels used analyze gears. The results only minor on dominated modification its deviation values.
