Abstract：Taking the gearbox of a 100mm lithium-ion angle grinder as the research object，noise reduction was investigated through a combination of theoretical analysis and ANSYS simulation aiming at its noise level of 75～ 85dB（A）. The mechanisms such as meshing impact were analyzed，and a simulation model with an error of ⩽ 3.5% was established.Improvements were made from the aspects of structure，assembly and processing. After optimization，the noise level reaches 68.2 dB（A）under no-load condition and 72.5 dB（A）under load condition， which meets the requirements of GB/T30270—2013 Information technology security techniques-Information technology security evaluation methodology，providing technical support for noise reduction of the gearbox.
