Abstract: In order to reduce the noise characteristics of the gearbox under certain working conditions, a rela-
tively optimal involute helical gear modification method was found. Based on the professional gear modification
software Kisssoft and multi-disciplinary integration software LMS Virtual Lab, according to the principle that
short gear profile modification can change the transverse contact ratio and overlap contact ratio of involute
helical gears, the magnitude of the sound power level of involute helical gears reducer without modification and
after different short gear profile modification methods to achieve a specific coincidence degree are compared
in this paper. The reason why the sound power level of the gearbox after short profile modification has
decreased significantly from 500 r/min to 2000 r/min is analyzed. And the reason why the sound power level of
the gearbox after short profile modification has not decreased significantly at 2500 r/min and 3000 r/min is also
